MIDI channel per staff and MIDI playback via controller
I have two synths loaded into a project. All entered notes in the score play back with the correct selected synth sound; but how do I get my SECOND synth to be the audible sound as I press the controller's keys? I am only able to hear the first synth as I press the keys on my controller. I'm assuming this may be a MIDI channel issue, but I'm unable to figure out the puzzle.
