Modulr Song

Rhythms with their own bass lines, arranged part by part over eleven steps, and written down as songs.

Modulr Song is a design study after a rhythm composer of 1981, drawn as a plug-in editor and as a 26 HP module. It borrows the instrument’s grammar: eleven preset rhythms with their bass lines and chords, a 32-note keyboard carrying the rhythm sounds, part buttons and an eleven-step arrangement.

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 Song plug-in editor, drawn as a design study — The Modulr Song editor: a putty case over a dark panel, an eleven-rhythm chart, 32 keys, eight voice pads, four parts over eleven sections.

The Modulr Song Eurorack module, 26 HP, in its case — The Modulr Song module, 26 HP: a charcoal panel, an amber read-out, eleven section lamps, the rhythm list and six knobs over their jacks.

Mock UI — drawn by the specification’s own kit, not a screenshot of a shipped editor. Values are illustrative, not measured. The study is RX-7’s grammar, redrawn in Modulr’s own words, and nothing on it is measured against the instrument.

The instrument it studies

RX-7, 1981.

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

The rhythm-composer grammar: eleven printed rhythm charts, a long row of narrow flat keys that carries the sound, square voice pads and part buttons with amber lamps, an eleven-section arrangement, a bank of thirty-two songs, a tempo knob and a small amber display.

A warm charcoal panel in 26 HP: the title in cream, a small amber read-out carrying the loaded rhythm, a row of eleven section lamps, the list of the eleven rhythms down the right, six dark knobs each over its control jack, and the jacks in a dark tray.

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.

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.
