## Why VST3 in an audio player?



More reasons than you would expect.



- **🎧 Headphone surround & spatial audio** — Run binauralizers like **dearVR MONITOR**, **Waves Nx**, or **Dolby Atmos Production Suite** to turn stereo into a full spatial soundstage on any pair of headphones. No system-wide wrapper, no virtual audio cable.

- **🎚️ Headphone calibration & correction** — Use frequency-response plugins like **Sonarworks SoundID Reference**, **Beyerdynamic Headphone Lab**, **Waves Nx Virtual Mix Room**, or **Morphit** to flatten your specific headphone model to a neutral reference.

- **📻 Internet radio & streaming cleanup** — Load a compressor, EQ, de-esser, or multiband processor on poorly-mastered streams or dynamic-range-compressed "loudness war" tracks to tame them while you listen.

- **🔌 Plugin auditioning** — Want to hear how that new reverb, saturator, or tape emulation sounds on real music? Drop it in. No DAW boot-up, no empty session, no audio import.

- **🔊 Loudness normalization & limiting** — Keep playback levels consistent across tracks from wildly different sources (old CDs vs. modern streaming).

- **🏠 Room correction** — Apply convolution IRs or parametric EQ profiles to compensate for your listening room and speaker setup.

- **🅰️🅱️ A/B plugin comparison** — Quickly toggle effects in and out on familiar reference tracks to hear exactly how they color the sound.

- **♿ Accessibility** — Hearing aid profiles, frequency boosting, dynamic range compression, or custom EQ curves for listeners who need tailored audio processing.

- **🎛️ Mix referencing** — Drop your mix in, compare A/B against a reference master, hear your monitor chain on someone else's material.

- **🎚️ Per-channel chains for trackers, SIDs, multi-channel chiptunes** — Each channel of a `.mod` / `.xm` / `.it` / SID / NSF file gets its OWN VST3 chain. Reverb only on channel 1, LP filter only on the bass channel, distortion only on the lead. Configure once per file (auto-loaded on track-change), bake into the export.

- **💾 Bake the effect chain into a file** — render any track or the whole playlist through the VST chain to WAV / MP3 / FLAC / OGG, faster than real-time. Take your processed audio anywhere. [Details below](#export-through-your-vst3-chain).



Up to **16 VST3 plugins in a serial chain**. Drag-and-drop reorder. Per-slot bypass and dry/wet. Smooth global chain mix. Native plugin GUIs. Everything runs at **64-bit double precision** end-to-end.

## Plays pretty much everything



FXChainPlayer is built for music listeners who do not want format juggling. Drop a folder with mixed MP3, FLAC, DSD, tracker modules, C64 SIDs, Game Boy chiptunes, console-game dumps — it just plays. Searchable Format Library panel built in.

### Atari ST & YM2149 chiptunes (`.sndh` / `.snd` / `.ym`)



Native **YM2149** sound-chip emulation with full **Motorola 68000** support (Timer-C, DigiDrum, STE DMA samples) — Atari ST and STE chiptunes (**SNDH** / **SND**) and standalone **YM** register-dump tunes (**`.ym`**, including the LHA- and ICE-packed files that fill the YM and modland archives) play **start to finish, out of the box, with no plugins and no setup.** Most players on Windows can't touch these without a separate add-on; here they just play, accurately, across the entire ~25,000-file sndh.atari.org archive.



And then they do what no chiptune add-on does: run a 1985 Atari demo tune **through your VST3 reverb, EQ or mastering chain in real time — and export it to WAV / MP3 / FLAC.** A piece of demoscene history, baked through modern studio effects into a file that plays anywhere.



### Amiga PreTracker (`.prt`) — full support, including 1.5



**PreTracker** (**`.prt`**) — the modern Amiga demoscene tracker by Pink / Abyss, heard in productions such as *Coda* and *Preschool* — plays **start to finish, out of the box, with no plugins**, and every song sounds exactly the way its author wrote it. That now includes the latest **PreTracker 1.5** productions from the current demoscene. Almost no player on Windows can open a `.prt` at all — here it just plays, and like every other format it runs **through your VST3 chain and exports to WAV / MP3 / FLAC.** (PreTracker 2.0 productions distributed as Amiga executables play too — see below.)



### Amiga executable music



A huge amount of Amiga **demoscene and game music ships as a raw Amiga program**, not a song file — and FXChainPlayer plays these executables **directly**. This includes the many that carry **no file extension at all** (the way the Amiga filesystem stores them): just drop them in and they play. It covers native exe-tunes and **AmigaKlang** productions, plus the path by which **PreTracker 2.0** productions play, and File Info identifies them on sight.

## DJ Mode





  FXChainPlayer DJ Mode — dual-deck console with Deck A / Mixer / Deck B, per-deck waveforms, BPM-Δ header, hot cues, EQ knobs, crossfader, and Pioneer-DJM-style filter




Press `D` (or click the DJ button in the status bar) to switch to a **dual-deck DJ console** built into the player. Drop tracks on Deck A and Deck B, mix with a real crossfader, and use everything you would expect from a DJ rig.



- **Two decks side by side**, each with: per-deck waveform (overview + 10-second close-up), title / artist / BPM / Key / Camelot, 8 hot cues (numbered, persisted across sessions, set / clear / colour-coded), Loop In/Out + Reloop, auto-loop chips (1/8 1/4 1/2 1 2 4 8 beats), beat-jump (`<<` `<` `>` `>>`), 3-band EQ (LO / MID / HI knobs, ±12 dB), gain knob, Play / Cue / Sync, SLIP / QUANT / BRAKE, and a **Pioneer-DJM-style filter knob** (sweep LP from 20 kHz down to 70 Hz on the left half, sweep HP from 20 Hz up to 17 kHz on the right half, magnetic dead-zone at the centre).

- **Crossfader** — four industry-standard curves (Linear / Smooth / Sharp / Hamster), per-sample smoothing (no zipper noise), right-click snaps to centre.

- **Sync engine — Mixxx-style phase-lock.** Single-click SYNC = match BPM AND beat phase to master. Right-click SYNC = make THIS deck master. Octave-fold so 175 BPM follower against 87 BPM leader stays at perceived-equal speed.

- **Vinyl scratch on the waveform.** Click + drag the close-up OR overview waveform like a Pioneer-CDJ jog wheel. Newtonian-physics platter integrator with viscous + Coulomb friction. Forward + reverse. Release lets the slipmat catch the platter back to slider rate. Works in single-track mode AND DJ mode with the same physics.

- **Vinyl-spin while paused.** Even when audio is paused or stopped, dragging the waveform spins the platter in the dragged direction. Friction decays the platter back to 0. Like spinning a turntable when the motor is off.

- **Per-deck Pitch ⇄ Stretch toggle.** Disc icon = Pitch (vinyl turntable, pitch + tempo move together). Gauge icon = Stretch (phase-vocoder, pitch stays constant while tempo varies).

- **Per-deck Echo + Gater FX.** Tempo-locked beat-rate chips (1/4, 1/2, 1, 2, 4 beats). Auto-syncs to deck BPM × pitch ratio in real time.

- **Your own VST3 effects on the decks.** DJ Mode taps the same per-channel VST3 chains as the main player — drop your favourite filters, delays, reverbs or saturators straight onto a deck and make them part of your mix, not just the master out. The exact plugins you already use everywhere else in FXChainPlayer, now in the booth.

- **Saved Loops + Smart Cueing.** Per-track named loop slots persisted across sessions. First-time-load auto-creates hot-cue 1 at the detected first downbeat. Quantize-seek snaps hot-cue jumps to the nearest beat.

- **Camelot wheel + harmonic-mix hint (experimental).** Per-deck Camelot key chip derived from a background key-detection pass or the file's existing key tag, with a colour-coded cross-deck compatibility hint (Match / Relative / Adjacent / EnergyLift / Discord). Treat the suggestions as a starting point — real-world key detection is imperfect across genres. Trust your ears.

- **Dual audio output.** Three modes: single device (DJ Mode runs without cue), dual WASAPI device (Main + Cue on independent endpoints — works with any USB DAC + Bluetooth combo), or ASIO channel-pair (Main on 1+2, Cue on 3+4 of the same multi-out interface). Pre-listen cue mix balance knob.

- **Tracker DJing — unique to FXChainPlayer.** Drop a `.mod` onto Deck A, an MP3 onto Deck B, hit SYNC. The tracker-tempo engine + offline beat-detector consensus matches Protracker / Fasttracker / Impulse Tracker and other tracker formats against modern dance productions accurately enough to mix demoscene tracks alongside MP3s on the same crossfader. **No other DJ tool can do this.**

- **MIDI controller support.** Hardware-detected mappings for Pioneer DDJ-FLX series, KORG nanoKONTROL2, Akai LPD8, Behringer X-Touch Mini, Mackie-Control, General MIDI. Ableton-style Learn Mode (`Ctrl+Shift+M`) for any other controller. Pitch / EQ / hot-cues / scratch jog-wheel / play / cue / sync / filter all mappable.



> **Beta status.** DJ Mode is feature-complete and stable for production use. A few rough edges are still being polished — per-channel VST chain audio routing has a small delay before plugins become audible (~5–30 sec depending on track length), and some scratch-ergonomics edge cases are still being refined. The DJ MODE pill in the header carries a small "beta" marker so you can calibrate expectations vs the rock-solid single-track player.

## Audio engine



### WASAPI Shared / Exclusive + ASIO 2.3



**WASAPI** Shared and Exclusive modes are the default Audio Mode. The player picks the device's native sample rate — no system-wide resampling. **WASAPI Exclusive** bypasses the Windows audio engine for the bit-for-bit path; works on any USB DAC, built-in sound, or HDMI output, no ASIO driver required.



**ASIO 2.3** is also supported (Steinberg-licensed) for users with a compliant audio interface. Pick **ASIO** in *Settings → Audio → Audio Mode*. Round-trip latency depends on your audio interface and the buffer size the driver supports — see *Settings → Audio → Latency* for the driver's live in/out frame counts and total ms.



- **Output Pair routing** for multi-output interfaces — route the player's stereo to any pair (1-2, 3-4, …) up to the driver's reported total. Persisted across sessions.

- **Configure Driver button** opens the driver's hardware panel directly (e.g. RME TotalMix, MOTU CueMix, Apollo Console, ASIO4ALL settings).

- **Driver-reported latency readout** — in N / out N frames + total ms — refreshed live.

- **Sample-accurate visual playhead** — the waveform playhead accounts for the audio backend's queued frames so what you see is what you hear, not what was written to the buffer 10–42 ms ago.

- **Output stage** — TPDF dither on every integer path, full coverage of common ASIO sample formats.

- **Safe driver panel calls** — a misbehaving control panel cannot take out the host.



### Per-Channel VST Chains



For every multi-channel format (tracker `.mod` / `.xm` / `.it` / `.s3m`, SID, NSF, SPC, GBS, every chip-emulator format), each separable channel can carry its **own dedicated VST3 chain** of up to 16 plugins.



- **Channel-tab navigation** — pick which channel you are editing

- **Per-channel chain editor** — full slot grid with plugin name, vendor, bypass, mix slider, edit (open VST3 GUI), move-left / move-right, remove

- **Auto-load presets** — chain configurations auto-load on track-change for matching files

- **Manual save / load** — save the per-channel chain layout as a named preset

- **Real-time playback** — pre-renders per-channel audio into a memory-budgeted cache, then routes through the per-channel chains live (cache build takes ~5–30 sec on first plugin add)

- **Export-path integration** — multi-track export renders each channel through its own chain to a separate file (filename template ` - .`; e.g. `MyTrack - Voice 1.wav`)

- **4 FX modes for export** — Master chain only / Per-channel chains only / Per-channel → master cascade / No FX



### Vinyl Scratch — Newtonian platter physics



Click + drag the waveform like a Pioneer-CDJ jog wheel. The mouse becomes your *fingertip* and applies torque proportional to slip; the platter has **real inertia** (calibrated to feel like a Technics SL-1200GR with felt slipmat) and accelerates / decelerates accordingly.



- **Fully bidirectional** — forward drag = audio plays at drag velocity; backward drag = audio plays in reverse at drag velocity (up to 8 s into the past via a rolling output-history buffer)

- **All techniques emerge from real physics** — baby / forward / chirp / tear / spinback

- **Inertia-aware release ramp** — calibrated against the SL-1200's 0→33⅓ RPM spin-up

- **Spin while paused** — flick the waveform on a paused track; the platter spins in the dragged direction and friction decays back to 0 (like spinning a turntable with the motor off)

- **Same physics in single-track AND DJ mode** for both the close-up scrolling waveform and the full-song overview strip



### Turntable Pitch Slider (Technics-style)



A vertical pitch fader on the right edge of the expanded waveform AND DJ-mode view. Selectable range (**±8 % / ±16 % / ±50 %**), **0 % center detent** (snaps to neutral within ±0.3 %), **33 ⇄ 45 RPM toggle**, and a per-deck **Pitch ⇄ Stretch toggle** (disc icon = vinyl-style pitch+tempo move together; gauge icon = phase-vocoder time-stretch with constant pitch).



**At 0 % the slider is bit-exact pass-through** — the resampler is bypassed entirely. Auto-resets to neutral on every track change.



### 64-bit double-precision signal path



Internal audio path is `double` end-to-end. Sample-rate conversion (when needed) uses a linear-phase resampler with ~260 dB SNR.



### BPM consensus + Camelot key detection



A multi-source BPM aggregator ranks candidates from up to eight signals (manual tap-to-confirm, embedded MIDI/CAF tempo, tracker-engine static tempo, ID3v2/Vorbis/APEv2/MP4 tag, CUE `REM BPM`, offline beat-detector, filename regex) with octave-fold corroboration and a contradiction cap. The badge tier reflects confidence — high confidence shows the value directly, lower confidence dims to `~XXX`, and uncertain results stay hidden so you never see a guess shown as if verified. Click the BPM pill to verify by tap-along.



**Key detection** runs in the background scan thread for every file. Results are persisted so they do not need to be recomputed. Every analysed file gets a Camelot wheel chip in the deck header AND in the playlist's Key column.



### MIDI controller input



Industry-standard MIDI input with Mackie-Control + General-MIDI defaults, plus built-in profiles for **KORG nanoKONTROL2**, **Akai LPD8**, **Behringer X-Touch Mini**, **Pioneer DDJ-FLX series**. Hot-plug auto-config matches known controller name fragments. Ableton-style Learn Mode (`Ctrl+Shift+M`) for any other controller. Mappings persist across sessions.



50+ DJ-specific trigger targets mappable: pause / stop / toggle / exitLoop / unsync / tempoLock / pitchRange × 2 decks, hot-cue Set 1-8 × 2 decks, hot-cue Clear 1-8 × 2 decks, scratch start/end + scratch velocity × 2 decks (jog-wheel rotation), filter, echo/gater amount + beats, autoloop halve/double.



### Format Library — every supported format, in-app



A collapsible **Format Info** card in *File Info* (origin, era, codec, decoder library) for every track, and a full **Formats Library** modal panel with a per-category sidebar, search across name / extensions / platform / developer / decoder, and click-to-expand cards with the complete catalogue entry. The redesigned **Settings → File Associations** uses the same source-of-truth.



### 3-Band EQ (built-in modal dialog)



Low Shelf / Mid Bell / High Shelf with two draggable crossover-frequency handles on a live FFT spectrum and three Low/Mid/High gain knobs. Smooth coefficient ramping. Soft 0 dB detent on bipolar knobs. Toggle with `Q`.



### Real-time visualization (9 modes)



- **FFT Spectrum** — log-scale frequency analyzer with Hz axis labels and a peak-hold trail

- **Spectrogram** — scrolling waterfall

- **Stereo Phase Scope** — Lissajous / goniometer with amplitude-brightening

- **VU Meter** — classic PPM L/R

- **LED HiFi** — 32-band segmented display

- **Frequency Landscape** — 3D waterfall with cubic depth fog

- **Pulse Thread** (default) — multi-octave audio-warped spine with audio-reactive starfield (GPU shader)

- **Chroma Drift** — 6 ribbons at parallax depths riding FBM flow fields with audio-driven domain warp (GPU shader)

- **Studio LED** — smooth HSV-interpolated 3-zone gradient with per-LED diffuser/die rendering (GPU shader)



Plus dedicated **Channel Scopes** (per-channel oscilloscopes for trackers up to 4 channels), a live **ProTracker-style Pattern View** for `.mod` / `.xm` / `.s3m` / `.it`, and the **SID Voices** view for Commodore 64 tunes.



### 🎨 Live Shader Editor



Write your own audio-reactive visualisation directly inside the player. A GLSL fragment-shader editor sits next to a live preview — press **Ctrl+Enter** and your shader recompiles and hot-swaps in a fraction of a second, no app restart. Audio reaches the shader as a texture (FFT spectrum + raw waveform), alongside built-in `iTime` / `iResolution` uniforms. Ships with a template library, and your own templates save as portable plain-text `.glsl` files you can share or keep under version control. One compile runs on every graphics backend (D3D11 / D3D12 / Vulkan / Metal / OpenGL).



![Live Shader Editor in action — GLSL fragment shader sitting next to a live audio-reactive preview, with two VST3 plug-ins in the chain and a MOD playing back](screenshots/liveshader.jpg)



### Studio Compare (A/B)



Dual-decoder synchronized A/B playback — load two files and switch between them sample-accurately with a short crossfade. Compare masters, codecs, headphones, plugin chains.



### Built-in Bauer-style crossfeed



Smooth your stereo on headphones without a plugin slot. Continuous blend slider, proper gain + delay + lowpass filtering.



### Gapless playback



Next track is pre-loaded and swapped in sample-accurately across formats that allow it (FLAC→MP3, MOD→XM, cross-format — all work).



### Integrated file browser & smart-scan



Point it at your music library. Background cache for VBR durations, bitrates, cover art, **BPM, Key, Camelot**. Instant playlist building. Breadcrumb navigation, library roots, "Play / Add All" context actions, Favorites tab.



### Export through your VST3 chain



Route **any file or whole playlist** through your VST3 effect chain and render the result to disk. Faster-than-real-time, offline, sample-accurate. Right-click a track in the playlist → **Export to format…** for a single file, or **Ctrl+E** for the full batch dialog.



Output formats:



- **WAV** — 16-bit, 24-bit PCM, 32-bit float

- **MP3** — 128 / 192 / 320 kbps CBR

- **FLAC** — 16-bit and 24-bit lossless (compression level 5)

- **OGG Vorbis** — q3 / q5 / q7 (≈ 112 / 160 / 224 kbps VBR)



Multi-tune containers (NSF / NSFE / SAP, multi-tune SIDs from HVSC, multi-subsong game-OST archives) can optionally expand into one file per subsong via the **Export all subsongs** checkbox. **Multi-selection** support — Shift-click a range, Ctrl-click individual rows, then export only the selected subset. **Per-row subsong picker** for choosing exactly which tune from a multi-tune file. **4-mode FX-chain selector** — Master / Per-channel / Both (cascade) / None.



Export is included in every build — no separate "Pro" tier.



### Plugin crash protection



Plugin process calls are wrapped to contain crashes, with automatic crash journaling, safe-mode after repeated failures, and per-`(path, classID)` blacklist so a single crashing plugin in a multi-class shell (e.g. Waves WaveShell with 600+ effects) does not take out the rest. An auto-restart watchdog subprocess recovers the host if something goes seriously wrong.



### Code-signed installer + DLLs



Every release is signed via Azure Trusted Signing — both the installer AND every shipped DLL (Qt, audio decoders, codec libraries, …) carry a counter-signature. Windows SmartScreen reputation builds quickly, and enterprise WDAC + AppLocker DLL rules allow the player without exception.



### Full keyboard accessibility



Every audio control reachable via Tab + Space / Enter / arrow keys. Output-pair, mode chips, device list all wired as standard radio groups. Settings panel, transport bar, file browser, FX-chain bypass, and playlist tabs all wired for keyboard navigation.



### Synced lyrics



Open the lyrics panel with **`Ctrl+L`** and the currently-playing track's lyrics scroll in time with the music — active line bold + centred, surrounding lines faded out, smooth auto-scroll on every line change.



![Synced lyrics panel — K-pop track with auto-scrolling Korean lyrics, active line highlighted, sidecar .lrc source](screenshots/synced-lyrics-panel.jpg)



Three sources, tried in priority order:



- **Sidecar `.lrc`** next to the audio file (community-distributed synced lyrics from lrclib.net etc.)

- **Embedded `SYLT`** — ID3v2 synchronized-lyrics frame

- **Embedded `USLT`** — ID3v2 unsynchronized-lyrics frame; the player still re-parses the payload for LRC-format timestamps because many taggers store synced lyrics in the USLT slot



A small badge at the top of the panel tells you which source was used. UTF-8 throughout — Asian scripts, Cyrillic, RTL text all render correctly. When a track has no lyrics from any source, the *Lyrics* entry in the status bar hides itself so the bar stays compact.



### Performance



Native C++20, lock-free audio thread, GPU-accelerated rendering throughout. Idle RAM ~50 MB, cold startup under 2 s on typical hardware.

## What's new in v0.65.4



Everything new since v0.62.4 — a big expansion of the Amiga and demoscene catalogue, plus a sharper DJ booth, smarter tempo detection and a full metadata editor.



### 🎶 Full PreTracker support — including PreTracker 1.5



Every **PreTracker** (`.prt`) song now plays exactly the way its author intended — including the modern **PreTracker 1.5** productions coming out of the current Amiga demoscene. The whole PreTracker catalogue, old and new, plays in tune and on time.



### 💾 Native Amiga executable music — a whole catalogue unlocked



A massive amount of Amiga **demoscene and game music ships as a raw Amiga program** rather than a song file. FXChainPlayer plays them **directly** — including the many that carry **no file extension at all** (the way the Amiga filesystem stores them). Just drop them in. This also covers **AmigaKlang** productions and is the path by which **PreTracker 2.0** productions play. A piece of Amiga history that most players simply can't open now sits in your playlist like any other track.



### 🎹 MusicLine Editor, TFMX and RJP — fully supported



- **MusicLine Editor** (`.ml`) — full synth playback: envelopes, arpeggio, sample loops, **multi-tune songbooks with every subsong selectable** from the transport bar, and the full **8-channel** productions alongside 4-, 5- and 7-channel tunes. The **entire demo catalogue published on musicline.org plays** — verified song by song.

- **TFMX** (Chris Hülsbeck — *Turrican*, *Apidya*, *Monkey Island* Amiga) — accurate, full playback.

- **RJP** (Bitmap Brothers — *Chaos Engine*, *Cannon Fodder*, *Speedball 2*, *Gods*) — plays.

- **AHX / Hively** and **AY** (ZX Spectrum / Amstrad CPC) chiptunes.



### 📼 Even more of the catalogue



Packed and crunched **ProTracker variants** (the ProWizard family — The Player, Promizer, NoisePacker, ProRunner and ~40 more), Amiga **LZX archives** (`.lzx`, Aminet), more game-music containers, and broader drag-and-drop so library-playable files are never turned away at the door.



### 🎛️ A sharper DJ booth



- **Pro beat-grid** on the deck waveform — beat ticks top and bottom, red markers on every downbeat, so beat-matching by eye is instant.

- **Scratch that moves the waveform** — the display tracks the platter: backward when you pull back, frozen on a vinyl-stop, snapping back to the groove when you let go (DJ decks **and** the normal player).

- **Fixed-size, readable console** on a 1080p screen — controls keep a legible size; tighter space steps whole rows aside instead of shrinking everything.

- **Mix two synth/tracker tunes at once** — SID, PreTracker, MusicLine Editor and TFMX all load onto the decks.



### 🎯 Tempo you can trust



A **third independent beat detector** now cross-checks every track against the other two. When all three agree, the tempo badge locks in solid — and the whole "another tool says 140, this says 70/280" class of octave mistakes is dramatically reduced. Your library re-analyses itself automatically.



### 🏷️ A full metadata editor



The in-app tag editor grew into a complete metadata editor: Album Artist, Composer, Lyricist, Conductor, Arranger, Label, Copyright, URL, Compilation, track and disc as *n/m*, a **0–5 star rating**, and **embedded cover art** you can preview, change or remove. Plus a sortable **Genre column** in the expanded playlist and a **manual BPM** field.

## What's new in v0.62.4



The Amiga demoscene's modern tracker and the Atari's YM chiptunes now play **natively** — reproduced by emulating the **Motorola 68000 CPU** together with the **Amiga Paula** and **Atari YM2149** sound chips, so they sound exactly as they did on the original hardware, then run through your VST3 chain like anything else.



### Amiga PreTracker (`.prt`) plays — on Windows, with no plugins



**PreTracker** (`.prt`), the modern Amiga demoscene tracker (Pink / Abyss, heard in *Coda* and *Preschool*), now plays start to finish in FXChainPlayer. These are tiny Amiga programs, not audio files — FXChainPlayer emulates the **68000 CPU and the Paula sound chip** to play them note-for-note as on a real Amiga. Almost nothing on Windows can open a `.prt`; here you just drop the folder and listen — through your effect chain, and out to WAV / MP3 / FLAC.



### Atari YM chiptunes (`.ym`) play



Standalone **YM** tunes (`.ym` — direct YM2149 / AY register dumps, including the LHA- and ICE-packed files that fill the YM and modland archives) now play natively alongside the SNDH / SND Atari catalogue — same **68000 + YM2149** engine, same out-of-the-box, no-plugin experience.



### Audition any one-shot, however short



Building a drum kit? The shortest one-shots — single kicks, snares, hats, stabs of a second or less — now play in full straight from the library, whatever your output device's sample rate.



---



## What's new in v0.61.6



Everything new since v0.55.2 — focused on real new capabilities: Atari chiptunes that run through your effect chain, VST3 plugins in the DJ booth, a DJ console that fits any screen, and sharper tempo detection.



### Atari ST music — played right, and now inside your effect chain



Atari ST / STE chiptunes (**SNDH** / **SND**) play start-to-finish, cleanly and accurately, **out of the box — no plugins, no setup.** These aren't ordinary audio files; they're tiny programs that drive the Atari's sound chip, and most Windows players can't touch them without a separate add-on. Here they just play. And then they do what no chiptune add-on does: **run a 1985 demo tune through your VST3 reverb, EQ or mastering chain in real time — and export it to WAV / MP3 / FLAC.**



### Your VST3 effects — now on the DJ decks



DJ Mode now lets you run **VST3 effect chains on the decks**, not just on the main player. Drop your favourite filters, delays, reverbs or saturators straight into your mix — the same plugins you already use everywhere else in FXChainPlayer, now part of your DJ set.



### A DJ console built for any screen



The two-deck console **scales from a 1080p laptop to a native 4K monitor** — knobs, hot-cue pads, loop and beat-jump buttons, faders, the mixer column and every label grow with the space you give them, and DJ Mode **opens fullscreen automatically** so nothing feels cramped. The key / harmonic-mixing chips, the beat-phase indicator and the BPM read-outs stay crisp and readable, and a loading indicator now shows when a track is being prepared.



### Mix two Commodore 64 SID tunes at once



Load and blend **two C64 SID tunes (`.sid` / `.psid` / `.rsid`) across both decks** — mix the Commodore 64 the way you'd mix records.



### Tempo you can trust



Every track is now analysed by **two independent beat detectors**. When they agree, the tempo badge locks in at full confidence; when a track is genuinely tricky, it tells you honestly instead of guessing — so the BPM you see is one you can actually mix to.



### Even more of the retro & demoscene catalogue



More vintage music plays natively, no conversion needed — including **NEC PC-98** game tunes, **classic DOS AdLib** game music, **high-resolution DSD** (including DST-compressed `.dff`), and a long tail of tracker and chiptune formats. The Nectarine demoscene web-radio stream even shows its own logo now.



### Smoother and lighter



The whole experience is steadier and easier on your machine — visualisers and analyzers go quiet when the window is minimised, big libraries import smoothly in one drop, and the player runs lighter when it's just playing in the background.

## What was new in v0.59.9



Headline features since the last public release: a way to write your own visualisation shaders, in-app tag editing, synced lyrics, listening-history tracking, the kind of social-presence integrations modern players ship with, and a smarter way to manage your own internet-radio stations. Everything that touches the network is default-OFF and opt-in — privacy first.



### 🎨 Live Shader Editor



Write your own audio-reactive visualisation directly inside the player. A GLSL fragment-shader editor sits next to a live preview. Press **Ctrl+Enter** (or the ▶ button) and your shader recompiles and hot-swaps in 50–200 ms — no app restart, no external tooling.



- **Three overlay states:** hidden (just the visualisation), peek (semi-transparent code over the effect), edit (opaque editor with a TextArea that takes focus).

- **Audio inputs as a texture:** `iChannel0` carries a 512×2 texture — FFT at `y = 0.25`, raw waveform at `y = 0.75`. Sample with `texture(iChannel0, vec2(x, 0.25)).x` for spectrum, `vec2(x, 0.75)` for wave.

- **Built-in uniforms:** `iTime` (seconds since shader load), `iResolution` (pixel dims), `qt_TexCoord0` (0..1 UV), `qt_Opacity`.

- **Template library:** built-in examples ship as `.glsl` resources; your own templates save to `%APPDATA%\Akustikrausch\FXChainPlayer\shader_templates\` as portable plain text — copy them between machines, share, version-control. Built-ins are write-protected; user templates managed by a Lucide-icon toolbar (save / load / delete / reset).

- **One compile, every backend:** Qt's `QShaderBaker` produces a single QSB containing SPIR-V + HLSL + MSL + GLSL ES 320, so the same shader runs on every Qt RHI backend (D3D11 / D3D12 / Vulkan / Metal / OpenGL). Compiled QSBs land atomically via `QSaveFile` rename — no torn-write window if you crash mid-compile.

- **Calm-on-silence convention:** the default `audio_trace.glsl` template gates motion magnitude on smoothed amplitude — when there's no audio the visualisation freezes (only a slow heartbeat drift remains). Your own shaders are encouraged to follow the same pattern so the screen doesn't look broken in a quiet section.

- **Inline error reporting:** GLSL compile errors surface in a red footer with the offending line numbers; click a line to scroll the editor to it. Red highlight on the failing line. Line gutter on the left for quick navigation.



### 🏷️ Tag Editor — fix metadata without leaving the player



Right-click any playlist row → **Edit Tags…**. Modal dialog with eight fields (Title, Artist, Album, Album Artist, Year, Track #, Genre, Comment). Saves back to the file in the right frame format for the container — works across MP3 (ID3v2), FLAC + OGG + Opus (Vorbis comments), M4A (iTunes atoms), APE, WavPack, Musepack, True Audio. Playlist row updates within milliseconds, no library re-scan needed. Empty fields leave existing tags alone — the "I only want to change Year" workflow people actually use.



### 📝 Synced lyrics — Ctrl+L



Press **Ctrl+L** (or open the **Lyrics** panel from the StatusBar) to see scrolling karaoke-style lyrics for the currently playing track. Three sources, in priority order: (1) a `.lrc` sidecar file next to the audio, (2) embedded ID3v2 SYLT synchronized-lyrics frames, (3) embedded plain unsynchronized lyrics. Auto-scrolls the active line into centre view, fades adjacent lines. Supports LRC's standard meta-tags (`[ti:]`, `[ar:]`, `[al:]`, `[by:]`, `[length:]`, `[offset:]` for global time-shift) and multi-timestamp lines for repeating choruses. Source badge in the panel header tells you which kind of lyrics you're reading.



### 💬 Discord Rich Presence



Show your currently-playing track on your Discord profile. Settings → Integrations → toggle on. **Default OFF.** Optional: hide the elapsed timer while paused (so the status doesn't broadcast "stepped away"). Connects via Discord's named-pipe IPC against your local Discord desktop client — your tracks never go to Discord's servers via us; only Discord itself sees the data via your own client. Auto-reconnects if Discord launches after the player.



### 🎵 Last.fm scrobbling



Connect your Last.fm account from Settings → Integrations → **Connect**. Browser opens, you authorise, the player picks up the session key. From there, every track that plays past the **50%-or-4-minutes** industry-standard threshold scrobbles automatically. The Now Playing badge updates the moment a track starts. Offline scrobbles are queued locally (up to 200) and flushed when you reconnect. **Default OFF.** Disconnect button to revoke. Per-track scrobble rules respect the Spotify / Apple Music / Audacious / foobar2000 convention.



### ⭐ Play count + 5-star ratings



Per-track listening history: play counter (increments at the same 50%/4-min threshold as Last.fm), last-played timestamp, first-played timestamp. Plus a 5-star rating widget — click stars to rate, click the current rating to clear. Playlist columns for Plays and Rating (toggleable in Settings → Integrations). **Data lives entirely on your machine** in the local SQLite cache next to your library scan — nothing leaves. Reset-all-stats button in Settings if you want a clean slate.



### 📺 CUE sheet splitting



FLAC + CUE album files automatically split into one playlist row per track. Per-track Title, Performer, BPM, Key, and start/end markers picked up from the sheet. The big "single 60-minute FLAC plus a `.cue`" archive format your audiophile friends use just works. UTF-8 BOM tolerated; foobar2000 + EAC-exported sheets parse cleanly. Seek and skip between sub-tracks like any other playlist row.



### 📡 Custom radio stream channel



The built-in stream-station directory (Demoscene, Classical, Electronic & Ambient, Jazz, BBC, Deutschlandfunk, …) ships locked — we curate, we update with each release, you get new stations automatically. To add your own stations: Settings → Streams → **Edit JSON**. Opens `stream_directory_custom.json` with a one-line example you can copy and edit. Save, click **Reload**, and your stations appear as the **Custom** channel at the bottom of the directory. Schema is a plain JSON array of station objects — five fields per entry, two of them required (name + url).



### 🎛️ Settings reorganised



Settings tabs are now sorted by frequency-of-use: Audio · Playback · Display (everyday) → Library (where your music lives) → Shortcuts · MIDI (input controls) → DJ · Integrations (optional feature subsystems) → Advanced (reset / danger zone, last). "Advanced" no longer sits in the middle of the tab list tempting accidental clicks.



### 🎚️ Visualisation polish



- **RGB Split Wave** redesigned as a true 3-channel chromatic-split waveform with calmer background and louder amplitude response on peaks.

- **Pulse Thread** is the new default analyzer for non-tracker formats (tracker formats still auto-pick Pattern View, SID files still auto-pick SID Voices).

- **Audio Trace** (the default Live Shader template) — clean blue-tinted Lissajous-style curve with rounded corners and calm-on-silence gating so it doesn't strobe during quiet passages.



## What was new in v0.55.2



Nine major game-music codec families became playable out of the box.



- **Sony ATRAC3, ATRAC3plus, ATRAC9** — PSP / PS3 / PS4 / Vita game soundtracks (`.at3`, `.at9`, `.aa3`).

- **Microsoft XMA1 and XMA2** — Xbox 360 and Xbox One game soundtracks (`.xma`, `.xma2`).

- **Microsoft xWMA** — XAudio2 streaming WMA-Pro.

- **FMOD FSB with Vorbis and CELT payloads** — used by roughly 1000+ game titles via FMOD audio middleware (`.fsb`, `.fsb5`).

- **Nintendo Switch NUS3-Opus** — Super Smash Bros. Ultimate, Splatoon 2 / 3, Super Mario Odyssey, Animal Crossing: New Horizons and many other Switch titles (`.nus3audio`).

- **Older Bink Audio (Speex variant).**

- **Ericsson G.719** — used by some reference video-conferencing recordings.



The bundled FFmpeg quartet is dynamically linked under LGPL-2.1+; the exact FFmpeg n5.1.2 source we use is bundled alongside the installer in the GitHub Release.



Plus DJ Mode highlights: **mix two C64 SID tunes at once** (load one onto Deck A, another onto Deck B, crossfade), and **waveform overviews for every chiptune format** in both DJ decks and the standard player transport bar — SID, GameBoy `.gbs`, NES `.nsf` / `.nsfe`, SNES `.spc`, Sega `.gym` / `.vgm` / `.vgz`, MSX `.kss`, ZX-Spectrum AY `.ay`, Atari `.sap`, PC-Engine `.hes`, plus every clean-room composer-named Amiga, Sharp X68000 and FM-TOWNS player.



## What was new in v0.49.0



The focus of that release was new functionality for C64 SID music, far wider DJ-controller support, and per-channel effects.



### C64 SID tunes



- **Per-voice VST effects for SID tunes.** A Commodore-64 SID tune is built from three independent chip voices. You can load a separate VST3 effect chain onto each voice and hear the result live — put a reverb on the lead, a filter sweep on the bassline, leave the third voice clean.

- **SID tunes on the DJ decks.** Load a `.sid` file straight onto a DJ deck and mix it like any other track.



### Per-channel VST effects



- **Live per-channel effects for tracker modules.** Apply a separate VST3 effect chain to each individual channel of a MOD / XM / IT tracker module and hear it during normal playback, not only when exporting.



### DJ controllers & MIDI



- **61 built-in DJ controller profiles.** Plug in a supported controller and it works straight away — full Pioneer DDJ family (DDJ-400, FLX4, FLX6, FLX10, REV1, DDJ-1000, DDJ-800, SB2, SB3, SX, 200), Native Instruments Traktor Kontrol S4 + Z1, plus a wide range of Numark, Denon, Hercules, Rane, Roland, Vestax and Reloop models.

- **Any USB MIDI controller works out of the box.** Even with no built-in profile, transport and mixer controls respond immediately. Anything the player can't guess is one click away in MIDI Learn Mode.

- **Searchable controller picker.** Type the first letters of your controller's name to jump straight to its profile.



### Playlist & export



- **Drag-and-drop M3U playlists.** Drop an `.m3u` or `.m3u8` file onto the playlist to load it.

- **Jump straight to your exports.** When a batch export finishes, "Open folder" and "Show file" buttons take you directly to the rendered files.



### Display



- **Plugin editors follow your monitors.** Drag the app between a 4K and an HD screen with a VST3 plugin editor open and the plugin re-renders crisply at the new monitor's resolution.



## Highlights since v0.37.2



A condensed summary of the bigger user-facing additions across the v0.38 → v0.46 cycle:



- **DJ Mode** (v0.39) — Dual-deck console, crossfader, sync engine, hot cues, loops, beat-jump, per-deck 3-band EQ, dual audio output, MIDI controller support, **tracker DJing** unique to FXChainPlayer.

- **Per-Channel VST Chains** (v0.45) — Each separable channel of trackers, SIDs, NSFs and other multi-channel formats carries its own dedicated VST3 chain up to 16 plugins. Real-time playback and export-path integration. VST3 chain limit lifted from 8 to 16 slots.

- **Format coverage** — Major expansion across the catalogue: Atari ST native (`.sndh`), PSF1 PlayStation OST, TFE TFM Music Maker, MDX Sharp X68000, Euphony FM-TOWNS, MSX `.kss`, 12 Amiga composer-named players (Hippel / Daglish / Whittaker / Symphonie / TFMX / RJP / many more), demoscene + retro synths (TIATracker / Organya / GoatTracker / SAP / ZxTracker / FutureComposer / Farbrausch V2), DOS Adlib, broader game-music coverage (ATRAC9 / XMA / FSB-Vorbis / Switch Opus), Apple CAF dedicated decoder, DST-compressed `.dff` DSD.

- **Vinyl Scratch — Newtonian physics** (v0.38) — Full platter physics for click-and-drag waveform scratching, forward + reverse, with Technics SL-1200 inertia and slipmat-friction restore. Works in single-track AND DJ mode. Even works while paused.

- **GPU shader visualisers** (v0.39) — Pulse Thread (new default), Chroma Drift, Studio LED.

- **BPM consensus + Camelot key detection** (v0.38 / v0.43) — Multi-source BPM aggregation with confidence tiers, offline key detection, Camelot wheel chips per track AND per deck, cross-deck harmonic-mix hint (experimental — treat as a starting point).

- **MIDI controller input** (v0.38) — Hardware-detected mappings, Learn Mode, 50+ DJ-specific trigger targets.

- **Sample-accurate visual playhead** — The waveform position matches what is being heard, not what was written to the buffer 10–42 ms ago.

- **Code-signed installer AND DLLs** — Every release is now signed end-to-end (relevant for enterprise WDAC / AppLocker deployments).

- Many stability improvements: mid-track playback recovery on transient decoder errors, concurrency hardening for bulk-add, gapless-transition fixes, DJ-Mode auto-recovery on tracker EOF, scratch-while-pitched safety, and dozens of smaller bug fixes across the v0.38 → v0.46 cycle.

## Download



**[⬇ Latest installer on GitHub](https://github.com/akustikrausch/FXChainPlayer-Releases/releases/latest)**



One installer, one click: `FXChainPlayer-Setup-X.Y.Z.exe` (Inno Setup). Full install with file associations, Start menu entries, uninstaller. All required Qt DLLs and the VST3 host process are included. **Both the installer and every shipped DLL are signed via Azure Trusted Signing.**



### Auto-update



FXChainPlayer checks GitHub Releases for new versions and offers one-click install with SHA-256 verification. Toggle in *Settings → Updates*.



---



## System Requirements



- **Windows 10** or **Windows 11**, 64-bit

- ~100 MB disk space

- An audio output device (WASAPI — any built-in sound, USB DAC, or HDMI audio works; ASIO 2.3 supported on any compliant interface)

- Optionally: a VST3 plugin folder with your favorite effects



---



## Supported plugins



FXChainPlayer is a **VST3 host** (not VST2). Any 64-bit VST3 effect plugin should work.



There is no compatibility list, no certification, no allowlist. Any well-behaved 64-bit VST3 effect should load. Tested heavily with **FabFilter**, **Waves**, **iZotope**, **Sonarworks**, **Tokyo Dawn Labs**, **Valhalla DSP**, **Acon Digital**, **Softube**, **Kirchhoff-EQ**, **Pro-MB**, **Dear Reality dearVR**, **Beyerdynamic Headphone Lab** and many others. Multi-class plugin shells (e.g. Waves WaveShell with 600+ effects) are crash-isolated per `(path, classID)` so a single misbehaving effect cannot take out the rest.



Instruments (VSTi) are filtered out automatically — FXChainPlayer is a playback tool, not a DAW.

Tools disappear. Music remains.
