I see what you mean. I just use switch 5 (right next to the pedal, and the easiest one to hit) to turn on/off my wah pedal, and then use Pedal A as the wah. At any other time, if switch 5 is not lit, Pedal A has a multitude of other functions (for every button on the board I hit, pedals A and B are assigned different functions). I keep two banks open for controlling my J-station, so that gives me 20 switches for the J: e.g one turns delay on/off, another is the tap-tempo for the delay, another switches between analog or digital delay, another triggers the "hold" function so that I can play overtop of a repeating loop, and the pedals in each case may be controlling delay level, # of repeats, mix level, fine tuning of delay length. Another switch turns on/off effects with the pedals setting the level and regeneration parameters, other swithces choose between chorus/tremolo/flange/phaser/rotary/detune etc with pedals setting speed and depth. Ditto for compressor/gate etc.
I then keep another 2 banks for controlling another multieffects unit. Another bank is currently being programmed to trigger loop playback in Sonar on my PC, this may occupy more than one bank in the end, as I have yet to set it up to my satisfaction. I also use a bank to trigger specific patches in my J-station that I need for certain songs I play live so that the delay/chorus etc come in just right.
I have found that this controller is one of the most versatile tools I have ever had! But, like I said at the start of this thread, it is about the only Behringer tool I have used that I would say that about
