Korg Kaoss Pad CV modifications and internal Color Organ

I finally figured out how to get 0-10 volt control voltages into and out of
a Korg Kaoss pad. A 10 volt gate signal is also generated when the pad is
touched.

It is somewhat tricky, attaching about 10 wires to IC pins on the surface
mount mother board. It also requires multiplexers and sample and holds.
About 5 additional chips.

There is also a working prototype of a five channel 20 LED "color organ"
that fits behind the translucent touch panel and gives you a light show that
responds to the sound coming through the pad. Psychedelic! This is simpler,
requiring only 5 motherboard connections, but the board is surface mount for
thickness reasons.

It is not practical to do this commercially since modifications void the
warranty. I just did it for fun and thought other people might think it was
fun too.

I'm guessing 10-20 people might have interest in these mods? That's enough
to maybe, make a kit with PCB? The CV interface and color organ are two
separate boards. I'm guessing each kit would be US$50 using hand made boards
with all parts and a Wiard sticker. You'll need enough skill to solder a #30
wire to a surface mount pin without creating a solder bridge and to assemble
the surface mount PCB.

Obviously this is another "senseless act of beauty" since $50 just covers
costs. If you would be interested these kits, or think you will build it
yourself if you had schematics, please drop me a line at
grichter at asapnet.net although it will be several months before I can follow
up on this.
