Modulr Cabinet

A cabinet of numbered modules: oscillators, a filter bank, amplifiers, envelopes, a sequencer and a ring modulator, patched by hand.

Modulr Cabinet is a design study after a wooden-cabinet modular of 1965: numbered black modules in ruled boxes, one knob and one jack per job, and cords patched between silver jacks.

The study

The editor, and the module it becomes.

Each study is drawn twice: as a standalone plug-in editor, and as a Eurorack module with its macro knobs and the control jacks under them. Nothing here is built.

The Modulr Cabinet plug-in editor, drawn as a design study — The Modulr Cabinet editor: a walnut cabinet of numbered black modules with cords, in three rows, the lowest with a four-octave keyboard.

The Modulr Cabinet Eurorack module, 40 HP, in its case — The same study as a 40 HP module: one combined voice, oscillator, filter, envelope and amplifier, in four ruled boxes with ten knobs.

Mock UI — drawn by the specification’s own kit, not a screenshot of a shipped editor. Values are illustrative, not measured. The study is Moog modular’s grammar, redrawn in Modulr’s own words, and nothing on it is measured against the instrument.

The instrument it studies

Moog modular, 1965.

The instrument’s own grammar, as the catalogue recalls it: the sections, the controls and the look the study borrows.

The cabinet grammar: numbered black modules in ruled boxes, one knob and one jack per job, a 24 dB low-pass filter with emphasis, an attack, decay, sustain and release envelope, and patch cords between silver jacks.

A walnut rail over a matte black panel with white engraved, numbered boxes: oscillator, filter, envelope and amplifier, ten big black skirted knobs with a printed scale and a white line, a CV jack under each, on silver hex jacks.

The spec sheet

The module, knob by knob.

The macros are the signature controls a player reaches for, not a generic set; each one has a control jack under it on the module.

Freq	osc.freq	16 Hz – 8 kHz	261.6 Hz
Wave	osc.wave	Sine / Tri / Saw / Square / Pulse	Saw
Cutoff	vcf.cut	20 Hz – 20 kHz	20 kHz
Emphasis	vcf.emph	0–100%	0%

Attack	env.att	1 ms – 10 s	5 ms
Decay	env.dec	1 ms – 10 s	300 ms

This study is a study, and it is not built.ProposedLegendary, the catalogue this study belongs to, holds 43 design studies after the instruments of all time, each after an instrument’s grammar and never a copy of it. No maker’s name or logo is drawn on a panel, nothing is measured against the instrument, and the study itself is not for sale: Legendary is the plan that carries the catalogue.

Legendary is the catalogue of the Modulr Synths project: 43 design studies drawn with the specification’s own kit, 33 after the synthesizers of all time and 10 after the drum machines. The makers and years named here are the instrument’s; the names, the layouts and every value are Modulr’s own.
