Sixteen drum buttons, a pattern you click in while it runs, and sixteen patches that each load a whole kit.
Modulr Click is a drum machine after the grammar of a 1983 rhythm composer. Sixteen instrument buttons with their lamps, a wall of level, tune, attack and decay knobs, a shuffle switch, and a sixteen-step sequencer of four lanes that you edit by clicking a square, even while it runs. Sixteen patches, each loading a whole kit and pattern at once, and sixteen memory keys that recall them.
Each clip is the plug-in itself: the patch is picked in the drawer and loaded, and its pattern runs from the Start key. Each patch is Modulr’s own groove for a style, named for what it is; it is not a copy of any record. The sound is the instrument’s own output, with no effects and no mastering.

The plug-in is built. The Eurorack module is drawn, with its macro knobs and the control jacks under them, and is not.

The editor is the plug-in’s own, as it opens. The module is drawn by the specification’s own kit, and its values are illustrative, not measured. The design is TR-909’s grammar, redrawn in Modulr’s own words, and nothing on it is measured against the instrument.
The instrument’s own grammar, as the catalogue recalls it: the sections, the controls and the look the study borrows.
The rhythm-composer grammar: a block of sixteen instrument buttons with their lamps, one column of level, tune, attack and decay knobs per voice hung on four rows named once in a gutter, a sixteen-step pattern read off lamps, a shuffle switch, a tempo and a memory of sixteen patterns.
A black case with an orange trim line round a warm white panel: sixteen instrument buttons with small lamps, a wall of tiny black knobs that are printed arcs with orange pointers, and a black jack tray.
The module is a design study and is not built. Its macros are the signature controls a player reaches for, not a generic set; each one has a control jack under it.

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.
