I hope someone can tell me how to play back a sequenced song without sound coming from the keyboard. I did this once by seeing how it was done and I have looked in the manual and can not find how to do this. I am so irked with myself not being able to find it. It seems like it is called Panic (?) I am unsure. Anyway, I would appreciate someone telling me how to do this. Also, can it be saved for future bringing up the song?
