G'day all

I, like many, very recently joined after re-acquiring a poly800 - my original
one in about '97 was the hapless victim of a power supply short-circuit,
frying the poor little bugger beyond repair...
Of course, this was my first synth, so it wasn't untill after said incident
that I found out just how cool it was, and how much I missed it...

Well, my recent acquisition set me back all of Aus$105 - yes, that's around
US$55!

Within a few weeks, it now features
∗ A memory backup battery (I was very suprised when I opened it, thinking the
"loss of memory" problem was a dead battery, only to find there was no
battery - seems it's one of the earlier versions before they thought to put
in the backup, but it did at least have the solder pads for it...)
∗ Filter cutoff and resonance knobs (a warning to those who haven't done this
yet - get a solder-sucker or something like that, the trimpots are EXTREMELY
hard to get off, 'cause you basically need to unsolder three terminals at the
same time!)
∗ SILVER buttons (the ones that were previously "white")
∗ A CHORME joystick knob (original knob was missing, apparently knocked off
by a flying beer glass at a particularly roudy wedding reception?!)
and, best of all
∗ A BRIGHT RED paint job!! Can you say "Nord Lead"?!? ; )

Any thoughts on my next big idea; putting in auxillary inputs to the filter?

My theory is two-fold:
1. Just use the knobs, enabling use of the poly as an external resonant
analogue filter module
2. The complicated way:
2.1: Connect another synth/sampler's MIDI out to the poly's MIDI in
2.2: Connect the synth/sampler's audio out to the poly's filter aux
input.
2.3: Set up a patch on the poly with DCO levels set to 0, and set the
filter envelope as desired
2.4: Playing the synth/sampler SHOULD(?) then feed it's sound through a
triggered poly filter envelope, allowing you to do my favourite, the
overlapped playing style with single trigger, which gives you a long envelope
sweep over your synth riff, etc... And you can also add to it with the knob
tweaking...
Get the idea? Of course, you could also set the poly's DCOs to actually
produce sound, thus layering the poly with the other source, all using the
same envelopes...

Anyone see any faults in my "logic"? Any thoughts?

hehe, sorry about the long post...
Pics of my poly should be going on my site once I get the film developed and
get access to a scanner...
