Fantastic work on the velocity mod, by the way! That's very impressive.
Cheers,

This isn't specific to the PolySix, but here are some guitar FX electronics sites that you might get some ideas from:http://www.electrosmash.com/

http://www.geofex.com/One very simple thing to try is to reduce one of the supply voltages (or add a DC offset to the input, which should be very nearly equivalent) on the voice summing op-amp stage, to give you (voltage-controllable) asymmetrical clipping, similar to the Moog CP3 module (which is quite a nice, musical effect in small amounts). Then again, it still probably isn't quite what you're looking for.
Alternatively you could grab a cheap guitar pedal from craiglist :) I have a box of them that I love trying out on my synths!

Hi All,
After my Polysix be velocity sensitive, I was really grooving on additional responsivness in the electric piano (EP) and clav sounds from my Polysix. But those EP and clav sounds weren't quite right...they were too clean. I needed a little more compression and more grit. So, I started to look into modifying the Polysix to give me some overdrive or distortion.
My first try was diode-based distortion. If you're interested, you can check out my write-up and audio demos here:

In the end, I decided that I didn't like the diode distortion. Oh well. I'll have to try something else. I think that my next attempt will be to add an overdrive capability to one of the LM13600 OTAs. We'll see if that sounds any better.
Does any of you use an overdrive or distortion for certain sounds with your Polysix?
