Thanks for the help. I'll try it & sounds like it should work.

Can the mini vent be used as a foot controller? I had a FC7 hooked up to control the onboard rotary effect & got rid of the effect on the botoom.

Yes. You're correct. Mono in, stereo out on the mini vent. Only using 1 output on the keyboard & yes KC series amp has 2 inputs per channel/
