Dave Smith Instruments SYNTHESIZERS

Hello,

i am having a problem with the poly-rack. 

when i switch combo (by hand or program change), the sequencers stop
playing. but if i am in program mode, it is fine, the seq does not stop.

my settings are:

_ evolver slaved to external midi clock.
_ Trigger Sel in the combos: SEQ/MIDI

I would really appreciate feedback on this. I know fairly well how to
use the mono evolver, and i need to say i am having a very hard time
moving to the rack.

thank you.

Mathieu
