Hi! You don't need to change the sounds from the controller if you want to make a kind of organ set up. See my post <3WStagea the arrangeorgan> and watch the video. I use a controller keyboard next to my PSR but it only sends midi notes info in one channel matching the receiving channel of the arranger as a song part. All the changes in the sound are made directly from the PSR manually or as a programmed registration change. If you have any doubt let me know. Good luck.
