I record MIDI phrases into the A4mk2 sequencer alot this way (no OB, MIDI sent over USB). The problem is that sometimes it records random extra notes into the sequencer and some notes that are long in Ableton are recorded with a very short note-length in the sequencer.
I am searching for a way to make it more accurate if you’ve any ideas? I’m recording 4 separate monophonic MIDI phrases (channel 1-4) to the four tracks, I’ve made sure no voices are polyphony enabled, and I’ve made sure that there’s no overlapping notes, using no more than 4 voices at a time, yet it still occasionally records with errors in the sequencer. Also I’ve record-quantize off and there’s plenty of resolution in terms of steps.
