When I play a sound, let's say Strings, on the Great from the PR-300, I get reverb that will not stop. I even turned off the reverb on Part 1 on the PR-300 and it still won't stop. Even on the organ, with Set+Transpose, I turned off the Reverb. The sound won't stop. When I put the same sound on the Swell, it works just fine. Anyone ever have a problem like this?
