Hi,

I use my CP40 as a main board in the band I play in. I have a Reface YC on the top rack, with a midi cable connected from the CP40. I switch between using the CP40 and the Reface YC. The Reface YC is also connected to a BOSS passive volume pedal, to mute the YC. If I just turn down the YC the internal speakers sound out. Sometimes when I switch back and forth, the YC loses it's volume function. Also sometimes the CP40 seems to be acting funny too. What is the best way to control the YC with the CP40 muted and play the CP40 without the YC inter-fearing.

Thanks.
