Thank you so much for your quick response! Sorry it took me so long to respond back, I was travelling and did not have studio one at my disposal for about a week. Any who, yes, this is my first go with presonus, and I've done what you said and edited the external track, enabling all the MIDI channels, aftertouch, program change, and pitch bend, but I'm still getting no sound when I try to play the track back. I've even messed around with the outputs and inputs and made sure that all the sound is going to my computers speakers and still nothing. Do you have any more advice?
