==============

LV2 plugins to filter MIDI events.

So far 29 MIDI event filters have been implemented:

*   CC2Note -- translate control-commands to note-on/off messages

*   Channel Filter -- discard messages per channel

*   Channel Map -- map any MIDI-channel to another MIDI-channel

*   Choke Filter -- trigger note-off events, create exclusive note-groups

*   Enforce Scale -- force midi notes on given musical scale

*   Eventblocker -- notch style message filter. Suppress specific messages

*   Keyrange -- discard notes-on/off events outside a given range

*   Keysplit -- change midi-channel number depending on note (and optionally transpose)

*   MapCC -- change one control message into another

*   Mapscale -- flexible 12-tone note map

*   Mapkeychannel -- 12-tone channel map.

*   Chord -- harmonizer - create chords from a single note in a given musical scale

*   Delay -- delay MIDI events with optional randomization

*   Dup -- unisono - duplicate MIDI events from one channel to another

*   Strum -- arpeggio effect intended to simulate strumming a stringed instrument (e.g. guitar)

*   Transpose -- chromatic transpose MIDI notes

*   Legato -- hold a note until the next note arrives

*   NoSensing -- strip MIDI Active-Sensing events

*   NoDup -- MIDI duplicate blocker. Filter out overlapping note on/off and duplicate messages

*   Note2CC -- convert MIDI note-on messages to control change messages

*   Note2PC -- convert MIDI note messages to patch/program change messages

*   NoteToggle -- toggle notes: play a note to turn it on, play it again to turn it off

*   nTabDelay -- repeat notes N times (incl tempo-ramps -- eurotechno hell yeah)

*   Simple 1 Channel Filter -- convenient MIDI channel filter

*   Passthru -- no operation, just pass the MIDI event through (example plugin)

*   Quantize -- live midi event quantization

*   Velocity Randomizer -- randomly change velocity of note-on events

*   ScaleCC -- modify the value (data-byte) of a MIDI control change message

*   Sostenuto -- delay note-off messages, emulate a piano sostenuto pedal

*   Tonal Pedal -- hold active notes when pressing the sustain pedal

*   Velocity Range -- filter MIDI note events according to velocity

*   Velocity Gamma -- modify note velocity curve by a gamma exponent

*   Velocity Scale -- modify note velocity by constant factor and offset

Install

-------

Compiling the plugins requires LV2 SDK, gnu-make and a c-compiler.

```bash

  git clone https://github.com/x42/midifilter.lv2.git

  cd midifilter.lv2

  make

  sudo make install PREFIX=/usr

```
