[sdiy] Evelope Follower

[Dr Strangelove]

Hi, I've been working away trying to build a little mono-synth but the next 
semester is nearly upon me so I'm revising my plans.  I've got a working 
filter I've built that I like a lot and I like the way all sorts of sounds 
work with it.  I am wanting to place the filter in a crybaby wah-wah housing 
and have the cutoff under foot control, I also want to have an envelope 
follower in there too with variable control voltage sent to the filter 
cutoff.  I'll place the knobs for input level, Envelope follower control and 
resonance on the top of the crybaby.  It should be lots of fun.

I cannot find a schematic for an envelope follower.  Can anyone direct me to 
a good envelope follower schematic, preferably a simple one?  I'm using +/- 
12v power. :-)
