I’ve recently started messing around with the ‘Midi Sends’ feature and have found it to be enormously useful for my workflow; however, it would be nice to have more than 4. Am I missing something, or is 4 the limit?
From what I have read, 4 is the limit.
One possible work-a-round:
Duplicate the MIDI/Instrument track
as many times as needed;
providing you access to more sends.
HTH (hope this helps)
