This is a microcontroller based module that combines an Attack-Release Generator with a delay.
It can be built in either +/-12V or +/-15V systems without any modification, and other than the pre-programmed microcontroller, uses no hard to find parts. It can be used with the expander from BMC003, to give voltage control over all of the parameters.
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for 1 PCB and PIC is $16.
Unfinished eurorack
panels are available for this project, they are 8HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
