Pitch bend intensity?

1999-10-20 by hodad1@xxxxxxxxxx.xxx

Ok, this is slightly off topic, but...
As I mentioned once before, I took the mod/bend wheel assy. from a junk
Polysix
& made it an out board controller for my MOTM--I feed voltage into it from
the 800 EG
& send it out to wherever.
My question: The Polysix has a Bend Intensity pot on the panel that
controls how strong a
pitchbend you get. What I'm trying to figure out is if I can make this same
principle work on
my little mod controller. Would the pot need to be wired on the ins or the
out? Is there
a need for additional circuitry?
I'm sure this would be fairly simple to figure out if I understood
electronics better, but
I don't, so I'm throwing it to the panel of experts in the hope that they
can guide me out
of the darkness.

Thanks

Junk Polysix? Can I have the circuit boards? ^^ Or the case? ^^ Futz,
the whole machine? I collect Polysixen for parts and resurrection.

My Polysix service manual is at the house, but after work today I can
snapshot the mod wheels portion of the schematic and place it on a web
server if you like.

I have plans to make a minimoog-style synth using MOTMs on a single 20U
to 24U wide upper frame that sits on a 'shelf' built onto the original
Polysix case. The more Polysix parts and cases, the better.

It's just a pot *in series* with the pitch-bend pot! Make it the same vlaue
as the pitch-bend
one, and you can get a decent range.

To be even more specific:

1 2 3
|_|_|
| |
|___|

(view of the back of your intensity pot)

1. pitch bend pot wiper (middle lug) - > intensity pot lug 3
2. intensity pot lug 1 -> ground and output jack ground
3. intensity pot lug 2 -> output jack hot
