 ## modules
 
-* 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 AR modes from Peaks and a weird tides-ish 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
