I’m pretty new here, but still want to share something I built.
I wanted to reproduce a loop from a song in VCV rack, in a sequencer, so I converted the loop to a WAV file, converted it free/online to a midi file, and built this Patch to convert that MIDI file into a PianoRoll Sequence using only free modules.
Highly experimental, may result in garbage, and could do with a lot of improvements possibly, but for me it did what I wanted, and maybe it is of use to someone else. Had fun building it anyway :).
Story on how it came to be and some hints as to how to use it are in Notes in the patch.
