Well, here's the thing.  Those touchplates a friggin' expensive.  $10 each -
my cost.  I think a better way of doing t would be real touchplates and I
would have to find out how much it would be to have something like PCB
material plated with nickel instead of solder. I've done a driver circuit
for a touchplate which is pressure sensitve, so that's not the problem.

Currently, I'm borrowed technology from Serge (he published it in Synaspe
for people to build, so it's pretty much public domain at this point) which
allows an external pulse to SEND to each of the keys - so it can actually
act as a sequencer, as long as you have a trigger sequencer to dish out the
pulses.

What I could do fairly easily is use Milton technology to make it sequencer,
even with voltage control of direction.  And adding a second, third or forth
bank of pots also wouldn't be not be a problem.

The only problem would be the accumulated price.  This thing to crawl up to
the $700 range pretty easily.  This is an off the top of my head figure, but
there's a lot of stuff behind this. ...but there are other things
brewing..(see next letter!).
