Welcome to my Eurorack module stash. This is a collection of modules I (partially) designed for use with eurorack synthesizers.

• bus: A tiny bus. not much to say.
• out: Befaco Outs on a separate pcb with SMD parts to manufacture it via JLC
• pure_adsr: Alternative firmware for the old GMSN Pure ADSR modules, using ADSR and mini sequencer modes from Peaks and a weird looping ADSR thing on mode 3
• stereo_mix: a 4 channel stereo (input AND output) mixer with voltage-controlled panning and volume. Digitally controlled via Multiplying DACs (MCP4922 in combination with MCP4822)
• vca: A dual channel variable slope (exp/lin/log) VCA based on easily available components
• vcf-20: MS20 style filter
• vcf-leiter: Moog style filter
