I just built this today and I've only experimented with it a little
bit. Some observations:

Input = ADSR (attack up, decay up, sustain 0, release 0)

During the attack portion the rising LED/output is lit/high.
During the decay portion the falling LED/output is lit/high.
When the envelope transistions from attack to decay the steady output
goes high briefly. At the end of the decay stage the steady output
FADES in and the steady output goes high and remains high.

I have two questions:
Is the steady output supposed to go high briefly at the point the CV
changes directions? Adjusting the pot extends this blip to be longer
or shorter but doesn't eliminate it entirely.

Is the steady output supposed to FADE in as mine does? It surprised
me because I thought it would be either full on or full off.

Someone please tell me if this isn't working right. Breadboards are
never bulletproof.

Ken. this is a nice addition to the line-up. I'm very impressed with
the simplicity to usefullness factor. The extra buffering for the LED
supplies is nice.

Thanks,
peng
