Scott, you said:
"Saving SOUND MEMORY in every sequenced song is a dangerous thing when one plays live because of the changing sound possibilities."
I can only say again what I said in the above post. All it takes to return to the settings you want, is a SD card load of less than five seconds and you are ready to play live.
Back to Custom Panel again. The answer to your question is "Yes".
I don't know exactly what you did that changed your panel memory setups or if they were even changed at all. A Custom Panel setup does not change other Panel Memory setups.>
