Hello!
I feel I've had this issue before but it's been a while since I've used the Aria Player in Cakewalk. So, I open up the instrument, put some patches in various channels because i don't know which one it is drawing from. When I click on a note on the keyboard at the bottom, I'm hearing the patch from Channel 1. When I use my MIDI keyboard in Cakewalk itself to record, it records MIDI but there's no sound on recording or playback. What am I missing? Thanks in advance!
