First Rack

QL-01 · 2 builds · modulation & utilities

Four low-frequency oscillators with their own rate and shape, from slow drifts of several minutes to audio rate. Each has an LED so you can see the movement. 8 HP, 35 mA +12 V.

LLF-02 · 2 builds · filters & effects

A four-pole transistor ladder filter with a fat, slightly gritty resonance that self-oscillates at the top. Cutoff CV with attenuverter and a drive knob for extra bite. 8 HP, 40 mA +12 V.

DAV-03 · 2 builds · sound sources

A through-zero analog oscillator with saw, square, triangle and sine outputs and a slow built-in drift for a warmer, less static tone. Hard and soft sync, linear and exponential FM, and a wide range switch for audio or LFO duty. 12 HP, 85 mA +12 V.

QVM-04 · single build · modulation & utilities

Four voltage-controlled amplifiers with linear or exponential response, summed to a mix output. Use it to shape notes, balance voices or attenuate CV. 10 HP, 45 mA +12 V.

SC-05 · 6 builds · cases & cables

A shallow eurorack case with black aluminium rails, a bus board with sixteen power headers and a bundled power supply. Sized by width in HP per row, two rows.

BM-06 · single build · modulation & utilities

Two buffered multiples that copy one signal to four outputs without loading it, so a pitch CV stays in tune across several oscillators. 4 HP, 20 mA +12 V.

DAE-07 · single build · modulation & utilities

Two classic attack-decay-sustain-release envelopes on sliders, with a loop switch on each to turn them into extra LFOs. 10 HP, 40 mA +12 V.
