Hi, here’s a tool I’ve made to play chords on chord machine tracks as actual combinations of notes.
It works by mapping the chord played on any connected midi keyboard to the nearest combination of note, shape and color values.
Doesn’t look like it would be hard to change the code, but I don’t have a Syntakt.
Maybe go to the github page for that project, and create a new “issue”, saying you are requesting support for Syntakt. That way the coder who wrote it might pick it up.
