Ladder Lowpass Filter
LLF-01 · 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.
Patch Cable Set
PCS-02 · 9 builds · cases & cables
Ten braided 3.5 mm mono patch cables with slim straight plugs that fit dense panels. Sold in sets of one length and colour.
Dual State-Variable Filter
DSV-03 · single build · filters & effects
Two independent 12 dB filters with lowpass, bandpass and highpass outputs, linkable for stereo or for a formant-style vowel sweep. 14 HP, 60 mA +12 V.
Twin Wavetable Oscillator
TWO-04 · single build · sound sources
Two digital wavetable oscillators with 64 tables each, scannable by hand or by CV. Run them as a detuned pair or as two separate voices. 16 HP, 110 mA +12 V.
Drift Analog VCO
DAV-05 · 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.
Bus Power Supply
BPS-06 · single build · cases & cables
A low-noise power module and bus board for building your own case: 1.5 A on +12 V, 1 A on −12 V and 1 A on +5 V, with a power LED for each rail.
Eight-Step Sequencer
ESS-07 · single build · modulation & utilities
Eight steps of pitch and gate on knobs and buttons, with clock in and out, direction modes and a quantiser for in-key melodies. 20 HP, 90 mA +12 V.
Tape Echo Delay
TED-08 · single build · filters & effects
A digital delay modelled on tape echo: wobble, saturation and darkening repeats up to two seconds. Tap tempo or clock input, and a freeze button for loops. 12 HP, 95 mA +12 V.
