## Included formats



- Decent Sampler



## Release notes



### Version 1.3 (2024-03-18)



- Tremolo depth can now be controlled by the modulation wheel

- Improved impulse responses for echo and reverb



### Version 1.2 (2023-11-13)



- Added a "Layered (Pitch Stretched)" preset.



### Version 1.1 (2023-08-29)



- Fixed typo (wrong casing) in the directory name for some samples, which caused the samples not to load on some devices.

- Added a "split" preset to play samples at normal speed and samples at half speed in different parts of the keyboard.



### Version 1.0 (2023-08-09)



- First version released



## Description



A music box recorded on to cassette tape and played back at half speed and normal/original speed. Playing back at half speed results in an octave lower pitch.



## Technical specification

### Instrument

#### Velocity and damping



- Velocity

  - Determines whether the velocity should affect the volume of the samples

- Damping

  - When damping is off, the sample will continue to play after you release the key (like a music box)

  - When damping is on, the sample will fade out quickly after you release the key



### Mixer

#### Volume



Mix between the normal speed samples and the half speed samples. They also have independent tremolo controls.



#### Tremolo



The **tremolo rate** and **tremolo depth** knobs enable you to modulate the amplitude of the sound with the desired depth and rate using a Low-Frequency Oscillator (LFO).



- Tremolo Rate

  - Tremolo rate determines the speed at which the modulation occurs

- Tremolo Depth

  - Adjust the Tremolo depth to introduce subtle or pronounced variations in volume



### Effects



These effects are achieved using carefully crafted impulse responses. The echo effect employs a Fulltone Tube Tape Echo recorded twice for stereo, while the reverb effect draws from a Chase Bliss Audio & Meris CXM 1978 reverb pedal with a room setting.



#### Echo

Select from two distinctive echo options: the short echo, delivering a classic slapback effect, and the long echo, characterized by a slower decay and numerous repeats.



- On

  - Turns the echo on and off

- Long

  - Switches between a short slapback echo and a long echo with slow repeats and high feedback

- Mix

  - Mix between direct signal and echo signal



#### Reverb

You'll also find two reverb effects: the short reverb, evoking the intimacy of a small room, and the long reverb, enveloping your sound in the vastness of a spacious environment.



- On

  - Turns the reverb on and off

- Long

  - Switches between a short/small room reverb and a long/big room reverb

- Mix

  - Mix between direct signal and reverb signal



### Fidelity

#### Hi-fi



When the **hi-fi** switch is turned on, no effects are applied. When it's turned off, some filtering, saturation and modulation are added for a lo-fi effect. The saturation becomes more pronounced when you turn up the volume in the mixer section.

  - Turns the lo-fi effects on and off
