Thanks for the detailed answer. All these years and I'm just now getting into editing, mixing, and all that. If these questions seem simplistic, it's because I never really did any of this before. I appreciate your patience.

The song is an easy recorded song on one disk, and I want to add a custom edited sound (Registration ?) from another disk to that Easy Recorded Song. I know how to do that with preset sounds, but not with custom sounds on a seperate disk

If I load the sound memory disk first, as you say, and then load the song disk, the song overides the previously loaded sounds with the easy record sounds. Am I loading the easy record song wrong ?

The reason for the question mark after registration ?
I'm not sure what exactly is meant by a registration.

Thanks once again.
Larry
