| @Grumble I didn't record the exact scope settings, but here's the idea: I both triggered the scope and gated the ADSR with a square wave VCO. I adjusted the scope until the square wave used about half the screen. Then I tweaked the ADSR times until I got what you see above. |

I am having so many problems with this.
First off, what is the purpose of the gate in being constantly switched on when not plugged in?
What values to use for 12v?
I know I need LOG instead of linear pots, but should 3/4 of the pots positions make the envelope non functional? |

hi mate,
the the purpose of the gate in being constantly switched on when not plugged in, could be that by doing so you have a defined state of the gate input
and, almost certain it has to do with the LFO funktion, cos the Release-Transistor is "blocked" then, if it would be "open" the lfo funktion would be hard to archive
the circuit should run on +-12V with no changes, only the eg-amplitude will be sligthly different
u can use linear pots without problems, the only difference is that in the "faster regions" you will have less "resolution", the sustain pot should be linear
i dont know what u mean by "but should 3/4 of the pots positions make the envelope non functional"? |
