… I create a MIDI clip containing a couple of quantized CC1 messages (RECORD). Using, for example, DUB-MODE in REPL-PUNCH, I want the H9 to capture quantized snippets of sound … I have strange behaviour from the H9, and a kind of MIDI overflow. What you think? What am I doing wrong?
Very strange. Sounds like you’re doing everything correctly. No MIDI loopback. H9 set to THRU (not the other 3 modes). A couple quantized CC1 messages (not too rapidly, 127 value long enough to be recognized). Hmm. Don’t repeated REC messages shift to DUB? Maybe a (from the example above – CC#3 – Value 127) STOP message in-between each CC#1?
The MIDI overflow is difficult to diagnose remotely. It’s been a long time since I used Live … I recall something about ‘kill timers’ at 100 mS. A MIDI monitor on the output would be your best friend here. Not sure if there’s one native to Ableton. WinX or whatever O/S you’re using. I’d check for Active Sensing, aftertouch, … anything in that clip or output that isn’t CC#1 or (probably) MIDI Clock pulses.
