Hey, there is a new SDK available for AnalogRytm, basically makes it possible to create custom programs for it.
I asked if something like this would be possible for digitakt, this is the awnser:
I’m sure it is possible. Since I don’t own a digitakt probably I won’t do it but my code is open sourced with MIT license so if any other developer should adopt techniques from it or reuse part of the techniques there they’re open to do so.
If in the future, Elektron decides to document and expose their sysex format I think the developer community and 3rd party apps will flourish and you’ll have more choices.
But unfortunately now without documentation the entry barrier is a little high since it requires reverse engineering.
