DIY music hardware, Eurorack modules, firmware, schematics and the engineering decisions in between. Built to be understood, repaired and reproduced.
CLOCK is the first South Signal Lab module developed end to end — hardware, firmware, simulator, tests and documentation.
Eight-channel Eurorack master clock, rhythm source and gate sequencer with a deterministic timing model, external sync/reset, OLED UI, simulator and a documentation pipeline designed as part of the product.
South Signal Lab modules with the documentation and source material needed to build, use and understand them.
Eight-channel Eurorack master clock, rhythm source and gate sequencer. Manuals, firmware, build documentation and hardware sources are collected here.
Current firmware releases for South Signal Lab projects and independent module reimplementations.
Firmware and reference implementation for the South Signal Lab CLOCK: an eight-channel Eurorack timing instrument.
Alternative C++/PlatformIO firmware for the Free Modular Quantizer, with calibration, presets, arpeggiation and automated tests.
Independent modernization of the Westlicht PER|FORMER firmware, simulator, build system, tests and documentation.
Alternative firmware for Free Modular Drift with organic and random CV modulation algorithms on Arduino Nano / ATmega328P.
Builds, firmware walkthroughs and practical Eurorack engineering from the South Signal Lab bench.
Schematics, PCB sources and assembly material for published South Signal Lab hardware.
Support keeps independent DIY electronics and modular-synth projects moving — from prototypes and measurements to firmware, documentation and publishable build material.
