Patches and discussion for Ensoniq VFX family

I can't seem to play locally from my SD1 when it's in song mode any 
idea's why?

I am hand playing a few things locally (from the SD1) and at the same 
time I reach up and start my SONG/SEQ, when the SONG/SEQ starts the 
sound I am playing stops. 
The SONGs/SEQs are not using any sounds from the SD1, they are all 
being played from a rack of other modules.
