I haven’t used Logic in many years, but surely it must be capable of recording MIDI CC messages in real-time (the MD could be used as the source) and drawing in automation data.[/quote]
It is, I just did it last week, some shortcuts you can’t record (like reload kit) but for most stuff it’s fine. I would suggest recording 1 msg at a time. Logic can definitely handle multiple, but if you want to edit it later it’s harder to find
