Dave Smith Instruments SYNTHESIZERS

I'm considering getting a PE/K or Evolver. I have a question first 
though...

In Combo mode on the PE/K, with 4 mono voices, could you have for 
example an envelope generator of Voice 1 modulate a source (filter 
maybe) of Voice 2? Or say a sequencer of Voice 3 modulate pitch of 
Voice 4?

So basically was wondering when in Combo mode, if the voices can 
interact/modulate other voices?

If not, I'll probably just get a dektop Evolver. My wallet (and wife) 
would be happier...
Thanks!
