It's strage that you brought this up, as I was looking at the
Poly800 just the other day and thinking about the exact same
thing, same meatodolog and all....trippy.
This is exactly how the Kawai k3m is laid out and the Esq-1 is
similiar too.
I imagine you'd go about it exactly how you put it across, using
momentary push buttons hacked ito the button key scanning
circuitry.
It would be some work, a couple of day's, but afterwards it really
would be a great interface for programming sounds, I know i love
the interface on the k3m (minus the desire for a rotary encoder).
I'd look into findind some easy to interface tactile switches for the
operation, ones which you can easily just drill a single cylinder
hole for, I've looked under the hood of the Poly800, there's is
plenty of space for mounting switches under the entire patch
sheet, so that's good to know.
How about this for a slim idea. Adding two analogue trigger
inputs for the up/down value key. Select the parrameter you wish
to control, then use an external drum machine (with trigger
outputs) to trigger the up/down value key, sought of a step
modulation input.
That might sound a little kooky, heres another idea that would
work. Modify the footpedal input at the back (which advances the
patch #) to accept a trigger input. Then, by saving a a bunch of
patches with slightly different parrameter settings, you could
rhymically switch the Poly800 through the different patches with
an external trigger (from a trigger equipped drum machine ie.
808 or 606), or, if the drum machine allready sends out
s-triggers (ie KPR-77), no need to modify the footpedal input, as
it advances when switched to ground)
Kooky yes, but i was able to do this on my k3m, and better still,
the Poly 800 doesn't thump when chaning patches on the fly like
my k3m :)
