Envelope Generator - GHz Labs (DIY Eurorack)

Tutorial / demo of my Eurorack Envelope Generator module.
A simple analog quad AR envelope generator. With gate inputs, attack and release controls. Two of the inputs are normalised together to conveniently generate multiple CV outputs with the same gate input. Can be utilised also as a slew limiter or envelope follower.
Each channel can be configured to have a different overall response length by using various capacitor values.

Great this, thanks Tomash. I was looking for something very simple like this!

You're welcome

Hey Thomas,
thanks for the great module design!
I experienced cv bleed, when there is no envelope triggered or in between the env.
Is there any simple way to change the offset?

[@TomashGhzegovsky]

Hi Fabian! What do you mean CV bleed, could you explain a little bit more what is going on and what you are expecting? There should be no offset if there is no connection to any input at all. Can you measure the output voltage with a multi meter or a scope?

[@TomashGhzegovsky]

Technically speaking, this module is actually a slew rate limiter, so whatever is on the input will be on the output but "slowed down"(it follows the input CV). If your input never drops to 0V for example, the output will never drop there either.

​@@TomashGhzegovsky Hey Thomas thanks for your answers took me a while to gain access to a scope :)
without any input there is an offsett 120-130mv...
I´ve added additional caps on channel 2+4 to get longer Attack/release values (all measurements were taken on channel 1 tho).
If there is an input on channel 1 there is an offset of 170 mv in between the envelope cycles.
