Hi Guys!

May you are interrested in a new Envelope Generator.

It started out as AD and then developed further to a "full" ADSR.

Critics and proposals for further developement are welcome.

cheers, bb

thx,
the middle one is untested cos of the lack of small-value-pots here.
The others i had on the Breadboard.
Find attached one more (tested) version.

Any critics / comments / findings are welcome.

Feliz Natal for us all,
GabBagAbi

As i have finally realized that i have never used the full ADSR functionality, and if i really would need i could mix a AD and a ASR thogether... if build myself some AD/ASR envelopes

i have used this schemo and this stripboard design.

That´s full of bang for the buck. I love that dual normal/inverse outs. It´s in the folder of TODO´s. I´ll report when I start the building Wink

Any common transistor should work, isn´t?
