It's amazing how much better things work when you actually provide solid grounding for all of your jacks, and you use either nice new potentiometers or cleaned up old ones.
I re-potted my VCA and re-wired the "output" module to be a generic attenuator, with the input normalled to my VCA's output. (It's actually normalled to the VCA's normalled output, so if I insert a cable in the VCA's output OR the attenuator's input, it breaks the connection. Maybe overkill, but what the heck.) The attenuator is currently linear taper pot, which doesn't work well for audio, so I may wind up replacing with an audio taper if I can score one. It still works fine for audio output as it is, and linear will be better for its other potential uses.
I also changed 1/2 of my A/R EG's pots from 5MOhm to 1MOhm. This means the total envelope time is much shorter, but I can actually dial in reasonable short times. So now I can either do the long, slow sweeps in the 5-10 seconds range, or a more manageable <2sec sweep. I found that the Microbrute's trigger isn't strong enough to run both A/Rs at the same time. Bummer, but I don't feel like buffering the trigger inputs at the moment.
The only module I have left with the old pots in it is my LFO, and it's still a little dodgy. I'll swap out those when my fingers are less tired. :)
But Wally's renovations are just about complete now, and I can start worrying about new stuff. The last truly wonky module is my "interface" module, and I can probably just gut that and re-solder it to be a multiples panel.
