How can I delete and add a wave from my expansion board to a patch? I followed the manual, and still couldn't get it. Can I add the same wave to all 4 tones and create that patch? Thanks to any respond.

Hello,
You don't delete tones from a patch, you simply turn a tone off in the patch edit mode. As far as selecting a tone from am expansion board, it should work the same way as any other tone when you select it in edit mode. All the tones should be available when you edit. If there's something in particular that's causing a problem, feel free to e-mail.
