Dave Smith Instruments SYNTHESIZERS

Hi.
Two days ago i bought a second hand evolver for 250 euros.
It has been updated to v.2.0.
I cannot sent midi notes to my Kurzweil K2661. I set an arpegiator
program to evolver,i sent midi out to kurzwil's midi in, i set the
same midi chanell, but kurzweil not responding. I know that evolver's
midi out works, because when i turn the programs knob, the programs of
my kurzweil change right.
Can anybody help me?

This machine is fantastic.
