Patches and discussion for Ensoniq VFX family

As mentioned, you probably have to turn it off for each sound. I've 
had problems with the velocity on a small midi keyboard, after 
pouring coffee over it (who would have thunk that). It was full 
velocity on any key stroke on two keys. Besides that, those keys 
lagged terribly, too. I got it almost fixed by cleaning it 
thoroughly, opening it and detaching the keys and the soft rubber 
bumpers on the board underneath the keys. Maybe cleaning everything 
possible could fix your after-touch, too.
