Moog 912 Envelope Follower - Modified....
video upload by noddyspuncture
"After finally getting my R.A.Moog 912 Envelope Follower working and calibrated recently, it was pointed out to me that it only 'swept' downwards. Good point... in it's standard form the CV it outputs, according to the level on it's input, always peaks high and then drops low. So I thought it would be an interesting project to modify it and have it be able to sweep both down and up. After building an op-amp circuit and testing it I replaced the 'threshold' pot with one of those push/pull guitar pots which has a built in switch - when pulled out it switches to the new 'sweep up' mode. I also installed an 'off-set' pot so I can alter the sweep 'window' for the new mode, which seems quite useful too...! Triggering from a drum machine for this demo and the CV out is patched to both pitch & filter."
