O.K. guys--you've been soooo helpful, thanks so much...how about this:
When trying to record to Calkwalk Pro Audio, with the PSR 2000, nothing registers...another Yamaha keyboard does work for me. "R" is set and getting a "playback" from other files on Calkwalk does work.
Seems like, there is a setting on the keyboard I overlooked (I did set the "host" to midi).
thanks-Riva
