Here are some SuperCollider classes for communicating with a SoftStep pedal in tethered mode:
https://github.com/X2theL/sc_softstep
Features:
- switch between tethered and standalone
- switch backlight on and off
- display text
- control leds (no yellow)
- classes for trigger, toggle, y-axis, x-axis, double-click, long click events
- unfinished documentation
This is a work in progress and is meant for people who have at least some experience with SuperCollider. All information for the midi communication protocol comes from these forums.
