I love Renoise, but sometimes I’ll start noodling on an instrument I have loaded in it on my MIDI controller just to get a feel for what music I want to be making with the sounds I have loaded, and no way to recover that so I can iterate on it later in FL Studio or Ableton or the like.
So I sat down and built an inline MIDI recorder using an arduino with an SD card module, so that you can always recover whatever sweet solo or chord progression you noodled, even if you forgot to press record, or aren’t even in software that does MIDI recording.
For folks who’ve been looking for something similar, maybe https://pomax.github.io/arduino-midi-recorder/ is useful to you, too!
