This is an all analog synthesizer module used to create new timbres and waveforms with your existing VCOs. It uses a CD4046 phase locked loop chip in combination with a binary counter to multiply the frequency of the input signal. It then has 7 outputs divided down from that multiplied frequency which are mixed together. It's simple to use and has a distinct sound.

Demos, build documentation, drill guide, are available here.

Unfinished panels are drilled by hand in my garage, they are bare aluminum that may be scratched.  They are intended to be painted, etched or otherwise finished later.

Pre-Assembled Modules are built after the order comes in.  Build time can be a few days or a few weeks depending on what parts I have on hand.  When ordering, please leave a comment at checkout if you have preferences on what color(s) the panel is painted.
