Thanks for this info. I used midimonitor and saw mostly sysex msgs being sent to the datalooper and only 2 control messages which were for a mod wheel on channel 2. My settings are exactly as in the userguide, I’m running the script, input/output are on datalooper, and the track/sync/remote settings are as directed. Before we continue I should ask: is this a Live 10 only feature? Because I have Live 9.
