NEW PCB REVISION: DIP package LM13700s have been replaced with SMD LM13700s due to the DIP package chip going out of production. All other parts are still through hole. If you'd prefer a PCB for a DIP 13700, let me know when ordering, they're still available.
This is an all analog synthesizer module used to make percussive pitched sounds.
The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters.
Listen here for an MP3 Demo of the module. I'm just sorta turning knobs in this. I have the output of the module patched into the Frequency CV and towards the end there is some self FM.
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 is $8.
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.
