Anyone have a Behringer FCB1010?

The latter.   Any pre-programmed MIDI Note On Number from 0-127 on a switch press; held until release of the switch sending the complementary Note On / Velocity of 0 (alternate "Note Off").  Of course, monophonic (one note per-switch), but 10 note number values per-bank.
 
Pressing another switch simultaneously will stop the original note from sounding, and replace it with the last note pressed.  The unusual quirk here is that every Note On velocity value is 64, with no adjustment possible, in the fine tradition of non-velocity keyboards from the dawn of MIDI.

Not being polyphonic shouldn't be an issue if you're using it for keyswitching.

It looks like I waited a little too long to add to this.  In my defense, I usually get virtual rolling eyes when I mention an event processor.  It may be the sysex programming (although the Programming Tools app creates it for you), or the the extra piece of hardware + expense.
 
I use the Event Processor Plus to translate the 5 Program Changes, switch CC's, exp. pedals' CC's, and MIDI Note on an FCB-1010 to something that I can use (usually MIDI CC's distributed throughout my pedalboard).  It's small, it's powered by the MIDI signal, and it retains its current programming on power-down.  Once you've programmed up to the 10 (or 32) event maximum, there's no need for a computer again until you need to re-program the device.
 
Nothing against the McMillen products; I've considered those versatile devices many times myself.  I just wanted to point out an alternative.  An FCB-1010 and an event processor cost close to one of the McMillen MIDI pedalboards without the almost-mandatory MIDI-DIN interface.
