Thanks for the feedback, Kim.  I agree.  A little bit of active electronics
is a better solution.  Especially since it would live in the rack with the
EDPs.

Ah, I see now.  I'd only need a sequencer type function if I wanted to
simulate multiple button press/release combinations (for changing number of
loops, switch quant., etc).  Humm, maybe I'll breakdown and buy a midi 
pedal
sooner than I thought...

Now, now.  You'll have me salivating with statements like this.  ;)
