Dave Smith Instruments SYNTHESIZERS

I'm seriously digging the keyboard.  It's a little embarrassing to 
admit, but I just love the way it looks and the talk of the keyboard 
action is very exciting.  My Edirol controller is lacking in the 
action, and it's a real hinderance to stylized playing.

But... I already own a Poly and a controller keyboard.  For space 
issues, two large keyboards is out of the question.  Can the PEK be 
used as a controller?  That is, can it transmit > 4 midi 
notes/vel/aftertouch simultaneously on the same channel?  Can it 
transmit > 1 note on the same channel?  Can the knobs be programmed 
to send a cc#?  

The last issue is the least important since I can buy a knob box and 
merge the midi if need be.  But the other questions (which are 
really the same question) are paramount.  Selling off two pieces of 
gear that work well together to get one that may not fill my needs 
is a fairly big risk.

Can those of you who have a PEK (PEKers?) address the midi 
transmission?

Thanks,
