ENV-100 6HP adsr by FEEDBACK [NEW module]

I made a pdf manual explaining the functions of ENV-100 adsr.

This is probably the fastest envelope generator in Modularland.
Why? Because it is based on the fastest one. The classic Japanese modular from the seventies everyone loves.
Why we did it? Because we wanted it in our own systems. And we wanted it in SMD.
Later we thought it would be nice to share it with other modular enthusiasts, so here it is.
The ENV 100 is a nice compromise. At 6HP is large enough so the user interface is not a pain to use, but small enough not to take significant space in your system.
It is a relatively fast build, with easy to find common parts and is adapted to work at +12/-12V eurorack power.

Tech specs:
- Panel width 6HP
- 35mm depth behind the panel, including the power connector
- 4 control pots : Attack, Decay, Sustain, Release
- 1 gate switch : triggers ADSR cycle
- 1 time switch : switches between fast and slow envelope times
- one normal and one inverting output jack 8V peak
- standard 10 pin euro power +12V/-12V
- power consumption +12V 20mA , -12V 15mA

FAST TIME
Attack Time 4ms-2s
Decay Time 8ms-4s
Sustain Level 0-8V
Release Time 8ms-4s

SLOW TIME
Attack Time 6ms-20s
Decay Time 15ms-40s
Sustain Level 0-8V
Release Time 15ms-40s

I made a movie demo for ENV-100.

ENV-100 fed into LO-FUSIONs freq input and cv input of VCA-100. In second part of the movie LFO-10 triangle output it's modulating the other freq input of LO-FUSION VCF. Signal source is the square output of TWO59 VCO.
VCA-100 is not in the system, is a work in progress module made on a testboard, soon to be released.

Looks good, vintage :sb:

If I was a customer, I'd love to see also the times for Slow mode. You could add a table.

Always good to be able to read back in the manual, what those values are :sb:

Almost complete. To finalize the manual now you must only add: "Use a fully functional thumb and another finger, put them around one of the knobs, grab it firmly, but not too firmly, twist is gently until the wanted value is reached and release the knob with love. Do not try to twist past the minimum and maximum. The warranty won't cover broken knobs." :mrgreen: :lol:
