Dave Smith Instruments SYNTHESIZERS

well this is odd...
if I turn the high pass filter to 1 the white noise goes away but it
just does not work right.

the sound is not consistant.  some notes may hardly sound while others
do.  

and the sound of the oscillators will come in and out at random when
no keys pressed.

I think Im going to call DSI on this one. but just wondering if im the
only one?
