Yes, there is some basic programming of the controller, but also of the MPX1 to assign the foot switches and pedal.
For me, the process of getting the system to work turned out to be quite complex. It was not as straight forward as I originally thought. For instance, for quite a while until I figured out how things needed to be set up, switching on or off a channel or patch would change how other channels were set up. This is a Lexicon issue, not the controller. I consulted the manual extensively, but it didn't seem to me to address this issue adequately. And of course, it could very well be that I still don't understand the situation fully. But what I have set up now works, and it seems to sound good to me.
