Looking for simple envelope generator

[mikmo]

I'm looking for schematics for a simple envelope generator that can run from a single power supply (9 or 12 Volts). I really only need it to be of the AR type, anbody have schems. for something like that ?

Thanx

i was looking at that today and im relatively sure that it contains an envelope circuit... keep clicking the next page button until you find it.

hope it helps

It looks like it is just about what i was looking for. And all the sub circuits of the mini synth has theri own schematics. So it should be easy.

Thanks a lot.

if you connect the base of an NPN to the output of this circuit. with the emitter to ground, is it possible to use this circuit as a variable resistance to ground like the envelope follower in a dr quack?
