Before you start
- How hard is it?
- EasyCopy a file or use a web page. No extra software.
- What you need
- A computer
- Can it break my device?
- Small chance of trouble, with a way to recover.
- Can I undo it?
- The project doesn't say. Assume you can't.

Compatibility
Devices: Elektron Digitakt.
No compatibility information yet.
Getting started
From the project's README ("Playing ModelDigi"):
Select ModelDigi as a track's SRC machine. Press SRC to switch between its two pages:
- OSC: oscillator ranges and waveforms, plus relative tuning for oscillators 2 and 3.
- MIX: the Analog switch, oscillator 3 control, modulation on/off and depth, and oscillator levels.
Other tracks keep their own sounds.
MIDI CC 16–23 control OSC; CC 24–30 control MIX in page order. Selectors use 0–5, and other values use 0–127. See Development for the companion-version requirement before testing saved sounds.
Risk and recovery
- Brick risk
- Medium
- Requires opening the device
- No
