Got a MIDI cable going In and Out of the computer and Out and IN on the keyboard? How's it connecting? Probably just have to make sure the cabls are correctly installed, and that the devie being used is enabled for both MIDI in and MIDI out sides under MIDI Devices (in preferences)
If that's not it, maybe the keyboard itself needs to be set to respond to all MIDI coming in. With a 'performance' or GM setting so it is multitimbral.


I do not work here, but the benefits are still awesome
