Hi, i have a litle problem with MIDI. I use notein to route notes with velocity to toggle the note position in a simple list on and off. With my MDIDI Keyboard everything works fine but if i use Ableton to send a prepared MIDI pattern to Max, the System slows down and the list hangs. After an 3min Pattern the List hangs 20 seconds, this means ableton is ready and the list plays 20sec longer. Have anybody some suggestions where the problem is?
