Mutron III decay control?

[Paul_5]

I've been playing about with a Mutron 3 clone and was wondering if it would be possible to put a decay control on it. I thought it would be something to do with the 4u7 cap on the output, but was wondering if anyone has already done this?

It would be that C(9?) 4.7uf on the output of the envelope.
Look at meatball/meat sphere/spectron.
They up the value of the cap to 10uf, use 100k with 1.5k in series from + to ground. Also they put in a series "attack" pot between the opamp and the cap, 100ohm fixed and 5k pot. Nice to have both controls. In my experience it should probably be more like 100ohms +2k.

The bigger cap allows really long decay. Synthy stuff.

thanks, I'll look into that. The Meatball is a Hella filter!!
