This is an all analog synthesizer module combining three different modules. There are two simple LFOs with triangle and square outputs and a range switch to put acheive audio rate oscillation. There is then a sample-and-hold module based on the LF398 monolithic sample and hold chip. The two LFOs are normalled to the inputs of the SH so that you can get random voltage output without having to do any patching.

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.
