I have a vibes sample I created and saved to a SET. When I load the new GrandTouchRX.SET and then try to load my vibes sound into that SET, it loads but some of the notes are fuzzy. Does anyone know what causes that? Is it a RAM issue?

What I want to do is create a SET with my vibes sample and only the first piano sound from the piano SET. I don't need all the sounds.

Suggest you also put your Korg question here.
