Hello,
I have a poly 800 that I'm thinking about modding and I want to know
what other mod beside the MoogSlayer would be best to add? I'm looking
to add just one more knob/switch so I was wondering what mod would be
best i.e. the FM mod or the db switch or the resonance mod.
Thanks!

I have a poly 800 that I'm thinking about modding and I want to know
what other mod beside the MoogSlayer would be best to add?Why not all of them ? >:) They don't exclude each other :) Btw. What did you mean by saying "resonance" (mod) ?

Thank you very much Marco. Did you do this mod? Is it worth the
effort? Can you use all the paramaters to modulate or to shape the
sound that you input in the Poly?

Thank you. I appreciate.

since the post linked in Marco's page has a mistake that will render
the synth virtually mute AFAIK....
Is the mistake is to remove all of the C103, I think we have to just
cut the positive leg, Am I right? And also, what do you think of this
idea of mounting a 100k pot in place of the switch?

I already got it. Thanks again and sorry for all those questions.

I've found some more infos about mods... Anyone can try em?
1.
"It seems that the most flexible way of Modifying the 12db/24db filter
capabilities would be to add direct output jacks for each of the two
filter
modes
+ one audio input jack into the chorus unit. This, I think, would be
the most
non-limiting mod you could do."
2.
"Another worthwhile mod (while on the subject), would be to add an On/Off
switch to turn the Noise Gate into bypass mode. I've found that the
Noise Gate
(Which is FET "F1" on the KLM-598 board), can indroduce a slight click
when
it switches + it seemed to be that it cut off the tails of the "Release
envelopes".
To add the bypass switch, use a SPST toggle switch to open/close a
connection between Transistor "DTA1" emitter & collector pin (One will
be the
middle pin of the transistor the other will connect to Resistor "R19"."
3.
"Also, If you've added the VCF Audio Input mod I posted, here's a cool
trick.
While monitoring from the headphone output, patch one of the Poly-800's
Line Outs back into the VCF audio Input. What this does is setup a Voltage
Controlled feedback loop, IE. Envelope 3 will control the feedback level.
So Imagine you set up Envelope 3 with a long Attack + Long Release
Envelope, when you hit a note, both resonance + Chorus feedback will
fade in
with the Attack, release the note and it fades out... Pretty nice
patch, you
have
to tweak the onboard resonance + the master volume knob to get useable
results, but once you found it, it's a beautiful sound."

Hi David
I'm interested to know a little bit more about this audio in mod. Do
you have schematic or something that you can share with this group?
It will be much appreciated.
Thanks
Bernard

Thanks for the response but I have two questions. How do you implement
the switch that toggles between factory setting and the moog slayer?
And does the audio in allow for a sound to be manipulated without the
need to depress keys, simply straight input and output?
Thanks!
