Dave Smith Instruments SYNTHESIZERS

Hi.
I recently purchased my evolver and am trying to get it to work with Matthew 
Davidson's freeware editor for OSX and am having no luck at all.

ive got a Midiman 4x4 interface and connected the midi out of the evolver to an in on 
the midiman and vice versa with the evolvers in to an out.. i turn the evolver on and 
set it to send and receive on whatever channel and launch the editor. nothing seems 
to happen.

I know the Midiman and cables are working as i use them with my Nord Modular and 
software editor..

Is anyone successfully using the OSX editor? i would appreciate any help.
Thanks.
