Eight modules, no filler. Voice, processing, modulation, sequencing, and utility. Filter by function below, or press the forward slash key and type to search. Every module ships with its schematic, its service manual, and a five-year warranty.

08 / 08 MODULES
VOICE / 42 HP

HELIOS-8

Eight-voice polyphonic voice architecture. Two analog oscillators per voice, discrete waveshaper, per-voice CV over everything that matters.

$1,290IN STOCK
PROCESSING / 18 HP

TESSERA

Granular sample processor with a spatial window engine. 2,048 grains, stereo spread per grain, and a scrub mode that treats the buffer as terrain.

$540IN STOCK
PROCESSING / 10 HP

KILN

Discrete low-pass filter with a thermal drive stage. The drive transistor heats on purpose and bends the response curve as it warms.

$310IN STOCK
MODULATION / 14 HP

MERIDIAN

Quad envelope generator with synchronized LFOs. Channels freewheel, sync, or retrigger each other until the phase relationship is musical.

$280IN STOCK
SEQUENCING / 26 HP

ARRAY-16

Sixteen-stage sequencer with ratchets, probability, and a skip engine that follows the beat instead of erasing it. Eight banks of A/B patterns.

$460IN STOCK
PROCESSING / 16 HP

FLUX CORE

Stereo multi-effect with a normalized feedback routing matrix. Delay, diffusion, and foldback on one page; any send back into any return.

$390IN STOCK
UTILITY / 8 HP

PHANTOM GRID

Four-channel clock, divider, and gate processor. Continuous swing from 50 to 75 percent, live-remappable outputs, no stopped transport.

$180IN STOCK
UTILITY / 12 HP

OBSIDIAN MIX

Six-channel mixer with per-channel drive and a performance mute group. Measured headroom, printed per batch, identical on every channel.

$240IN STOCK
Every price includes the schematic PDF, the service manual, and the firmware source under CERN-OHL-S. There is no paid expansion and no dongle, and there never will be.
A Reading the panels

A panel is a wiring diagram you can touch.

Each faceplate is drawn from the module's actual signal path: signal flows left to right, control voltage flows bottom to top, and anything drawn with a heavy stroke is normalled inside the module. The silkscreen uses the same values the calibration bench measured on your specific unit.

If you can read a schematic, you can read a panel. If you cannot, the manual teaches both at once.

04 Buying without a guru

The first three modules

If you are starting a rack from zero and want one order that will not need a follow-up apology, ours is HELIOS-8, PHANTOM GRID, OBSIDIAN MIX. A voice that keeps tuning, a clock, and a mixer. That rack plays for an hour without a computer and teaches you what your second order should be, which is knowledge no online forum can sell you.

The second order is where taste enters: TESSERA if you think in samples, MERIDIAN if you think in motion, ARRAY-16 if you think in patterns. Nothing about that sentence is a ranking. It is a description of how the three kinds of players differ.

The questions we would ask you

  • What do you already own, including the case and the power supply? The answer changes everything after it.
  • Do you want to play the rack or program it? Both are honorable. The modules differ.
  • How many HP are actually free in your case? Count twice; sell none.
  • What is the one sound you keep trying to make? Say it plainly. The bench has a patch for almost any plain sentence.
