Have not encountered that. Although I got a stuck note one time playing 
it through vkeybd. Normally I unstick it by playing the same key again, 
but that didn't work. So I improvised around with that one note stuck 
until it finally disappeared on its own.

I don't hear anything like that at all from Yoshimi or Zyn. Makes me 
wonder if there's something else wrong with your audio setup that's 
causing this to happen.
