PreRoll midi effect

Here’s a video in wich I show some Teensy DIY project done with IA and mostly a PreRoll midi effect.
Wich is similar to a roll except notes are generated before the selected ones
The machine is basically a multicanal remixer, to copy, move steps etc… not for a single track but the whole pattern.
Unfortunatly unstable above 100bpm actually. I don’t know if it’s GPT unable to code a good midi sequencer or Teensy CPU limitation

I will put the full code with the full lenght video so if Squarp can put it in Hapax that would be cool
I will probably do english, italian and german versions. Each one with different exemple track (I did italian today but at 140bpm totally unusable)
