VC ADSR

from $10.00

Description/Usage

10hp

This is a somewhat lazy design, but a nice easy build..

Basically grabbed the classic Jacky/Kirschman 555 ADSR circuit from 1980 and replaced the pots for Attack, Decay and Release with LDRs inside black boxes (BBX).

Not sure why it hasn’t been done before, it is a simple circuit and the results are fun; lots of wobbly, evolving envelopes.

Assembled modules are built to order. They will be ready to ship within 1 week of ordering, usually I manage it in 1-2 days.
