Midi sequencer for pd-l2ork (Purr-Data : https://agraef.github.io/purr-data/ ) including Ableton-Link support.
This sequencer is heavily based on the sequencer of the Roland SH-101, i.e: time data and note data are separated. There is a scale constraint option based on the scales of the Zaquencer ( https://zaqaudio.com/ ).
