I finally got my Afterlife up and running (I put it on the "WTF did I do wrong?" shelf for a month as it didn't seem to work at all, and noticed the other day that I had the Vactrol reversed... considering that I build circuit boards for a living, that was a pretty boneheaded move).
So, sounds great, but I'd love to get a little more control over the Attack and Release.
It looks like I could put a 50k or 100k pot in series with R7 to make an adjustable sensitivity.. this should translate to an adjustable attack, but I'm at a loss as to how to make a pot setup work with C3 for the release... I don't think an RC filter is going to do the trick...
The pot with R7 sounds right for attack. For C3, perhaps a 50 - 100k pot in series with the cap?
I used a 1M pot in series with C3 for the release control. It diminishes the overall compression, but definitely lengthens the release. As for the attack, on my build I reduced R6 and put a 1k pot in series with it (this was Jon Patton's idea, and it works pretty well). Both of these mods are *highly* interactive with the sensitivity control, though.
reviving this. could you put a few caps on a switch in the C3 spot for attack control?
or maybe R6 as a pot is a better idea
