Ableton Forum

Solved MY problem (I'm using python with pygame's midi wrapper)! I think. :lol: If the latency of the midi device is set to 0 (which may be default), timestamps aren't sent with the midi message, which Ableton doesn't like.

Very frustrating for sure! Same thing happened to me. I thought maybe it was lack of timestamp coming from my MIDI source (a python script which uses pygame's midi). Blinking "midi in" light on Live but NO audio output from the synth I was trying to trigger...
