Dave Smith Instruments SYNTHESIZERS

Hi there

I just got myself a programmable midi knob box and am using it to
tweak a DSI Desktop Evolver (v.3) - everything works a treat except
for the foot controller. According to the manual this should operate
on CC3 (the breath controller works fine on CC2 for example), however
nothing seems to happen when I set it up this way. Am I missing
something? Has anyone else had similar problems? 

I'm very keen to get this working, so thanks in advance for any
suggestions or advice.

Mark
