Hi Tim,
What great news that there's at least more that one other Tyros owner in AZ!!!
I've been looking for someone to share knowledge/experience with somewhere in the state and so far haven't had any luck.
I came to the same conclusion and hooked up my other foot pedal to accomplish what I wanted. It's a shame that with all the things the MFC10 will do it won't do something as basic as control volume on all parts.
Thanks again for you input. I'll send you a personal email to see if you're interested in networking to share our collective knowledge.
Stay cool!
