Dave Smith Instruments SYNTHESIZERS

Related question:  when the amp output is in "mono" mode, do both of 
the main outs on the evolver ouput the same thing?  In this case I 
should just be running one mono out from either the L or R ouput of 
the evolver to my mixing board. Problem is I like to use both stereo 
and mono patches in my liveset and don't want to constantly be 
plugging and unplugging that cable.  OK, I'm verging on answering my 
own question, but would still appreciate any help...
