modulr · the audio suite

Patch anything into anything.

33 instruments, twelve effects, a rack and a hub — all on sale, and all made to work together.

Every product shares the same sockets, so sound from one can steer another — patch them like hardware. Everything you do can be undone, one step at a time. Your sounds and settings are saved as plain files you can open, copy and back up. Everything is on sale.

Modulr Tension: the editor
Modulr TensionSpring reverb

Modulr Lattice: the editor
Modulr LatticeAlgorithmic reverb

A reverb you set up like a room: drag the walls, walk around in it, hear where you are.

Modulr Ferrous: the editor
Modulr FerrousSaturation

Transformer, tape and tube warmth, in any order — turn each up until it sounds right.

Modulr Drift: the editor
Modulr DriftChorus and ensemble

A chorus with the wobble of old hardware: warm, wide, and never quite the same twice.

Modulr Tidal: the editor
Modulr TidalDynamics

A compressor you can see: drag the waterline and watch the sound bob above it.

Modulr Comp: the editor
Modulr CompMulti-style compressor

Six compressors in one — pick the character your track needs, from clean and invisible to glue.

Beside the suite

Roadie. A command palette for the DAW.

Not a plug-in — a small app that sits beside your music software. Press one key, type what you want in plain words, and Roadie shows you the plan before it does anything. Anything risky is previewed first, everything can be undone, and the optional assistant suggests — it never acts on its own.

The palette is redrawn from the Roadie specification’s own wireframes. Mock UI — redrawn from the Roadie specification’s own wireframes, not a screenshot of the shipped app. Values are illustrative, not measured.

Legendary

The catalogue: forty-three studies, each drawn twice.

Legendary is our love letter to the instruments of all time: 43 studies, 33 after the synthesizers and 10 after the drum machines, each drawn twice — once as a plug-in’s screen, once as the rack module it would be. The five below open the list.

LegendaryThe catalogue, carried by a planOn sale

Every drawing is the specification’s own kit, not a photograph of a shipped instrument. The studies are drawings, not plug-ins: none of them is built, and none of them is sold on its own. Values are illustrative, not measured.

The suite

Everything in the suite, on sale.

Ten products on one framework: the synth, seven effects, the rack and the hub, each with its own editor, its bar against the field and its parameters. All on sale.

Installer, licensing, presets, updates

→

Every card shows the product’s editor. Mock UI — drawn from the specification, not a screenshot of the shipped editor. Values are illustrative, not measured. The synth’s is redrawn from the Modulr Synth prototype (v0.1).

Three differences

What the suite does that the pages we read do not describe.

Each one is rooted in something the framework already does, and each carries the limit that stops it being a claim of fact.

01

One journal for undo, audit and scripting

A knob drag, a cable edit and a preset load are each one reversible row, and every editor action is a command a script can send.

Where it stands:Tagged Measured on the synth; the journal keeps 4,000 commands in memory and is not saved with the project.

02

A signal from one product drives another

In the Rack, any output jack cables to any input jack: a compressor’s reduction can pull a band of the equaliser.

Where it stands:On sale in the Rack. The figures for it are the book’s targets, not measurements.

03

State you can read without the plug-in

Presets and projects are JSON with a schema stamp, never binary. The synth’s eight factory patches are one 7,864-byte file.

Where it stands:Measured on Modulr 0.1.0, without a version field; the stamp and migration are as the book specifies.

How to buy

One licence file. Buy it, or rent it.

Licence

A signed file

A licence is a signed JSON file read at load, capped at 4 KiB, checked with a key built into the plug-in.

Proposed

Licence

Never a hostage

A lapse never alters a saved project, a preset or audio that is playing; it changes only the next DSP object.

Proposed

Licence

Bought once, or rented

A plug-in, a synth and Roadie are each bought once, with an offline route, the model FabFilter sells on; the whole suite can also be rented by the month. The book rejected subscription-only, and the one-time prices stay beside the plan: it is the bundle plan with an expiry that Table 25.3 says only measured demand would reopen.

Proposed

33 instruments, twelve effects, the rack, the hub, Roadie and Legendary are on sale.ReportedOn the owner’s word of 24 October 2026, and of 28 October 2026 for Legendary, which was named and priced beside the suite that day. The only measurements on this site are Modulr 0.1.0’s: a VST3 module and an Audio Unit v2 component for macOS on arm64, loaded in Ableton Live 12.4.6 and in the in-repo probe. Every other figure is the book’s budget or target, tagged as the book tags it.

Every figure on this site is from “Modulr — the audio suite: design and architecture specification”, October 2026, and carries that book’s tag: Measured, Proposed, Estimate, Reported or Open question. The one exception is the prices: they are the owner’s, set on 24 October 2026, and neither book names one.
