On my PSR-S770, I was going through the Voice >> Synth folder, which I had not often done previously. I found that if you pressed the Synth button, followed by the "Up" button, I found folders that I had never seen before.
Specifically, there were folders named "Legacy", "Mega Voices", "GM & XG", and "GM2". Some I believe are duplicates from other folders. But some are new to me.
Does anyone know the story behind these Voice Folders?
Thanks.
