I need to get data from a regular Max patch into a M4L device. I have no problem doing this when the editor is open (via a send/receive pair), but as soon as I close the editor, I can no longer make the 2 patches talk.
One would think that by selecting the M4L device name as the output for a ctlout object, this would send cc messages directly to that device, but this does not seem to be the case.
If the M4L device is not in edit mode it can receive MIDI only from the Live track where it is loaded. So you’d need to send MIDI from the regular Max patch to a virtual port and choose that port as input of the track.
