The toolkit for agentic audio

Build the music tools you imagine.

Effects, instruments, MIDI tools and sampler kits. Describe them to an agent or write the code, then play them in the browser, your DAW or on hardware.

What's now possible

MoodboxTetra BoxStemSep

Generate sound that belongs together

Whole kits from one idea, morphing between kits, and stems from any track. The models run for you.

TerrainLiveTransferAccompanist

Play neural models live

Explore a learned sound space like an instrument, restyle live audio, or jam with an accompanist.

PitchyVocoderGroove MIDI

Turn playing into data

Sing or play, and get notes and expressive pitch back. Vocode any input. Browse human drum performances.

Hand ChordHandModCamMod

Play with your hands

A webcam becomes a controller: strum chords in the air and map gestures and motion to MIDI.

Code SequencerPretty ChordImprosax

Compose with code and theory

Patterns written as code, 136 chord banks and lead-sheet practice. Music theory your agent can write.

Room AcousticsCapture PlayerAmp Rig

Model real spaces and gear

Place a sound in a simulated room, play neural amp captures, and run a tube drive into a real cabinet.

HandpanMouth SynthPolySlide

Build expressive instruments

Physical models of steel and strings, a vocal tract you play like a synth, and polyphonic pitch gestures.

MetergramLoudmatchPlosive Repair Lab

Ship studio-grade tools

Visualize, loudness-match and repair audio with tools you can measure, not just hear.

MultifxWavetableMaru Sampler

Start from classic tools

60 named effects in any order, morphing wavetables and a sampler for your own recordings.

Browse all 110+ modules

Remix an example

  1. 1. Pick one that's close

    Play any of the 110+ instruments, effects and MIDI tools in your browser.

  2. 2. Edit a copy

    Use Edit a copy on its page to get the full source and presets.

  3. 3. Let your agent change it

    Ask for a new control, filter or face. It edits the source and checks the build.

  4. 4. Recombine

    Chain modules in a rack, or pair one's DSP with another's interface.

Three ways in

Create in Studio

Describe it, then play it in your browser. No code.

Open Studio

Build with your AI assistant

Add the Maru connector to Claude, ChatGPT, Codex or Cursor and ask.

Connect your agent

Build in code

Compose the SDK, DSP and UI kit, then build VST3, AU or CLAP.

Read the quickstart

Everything in the box

110+ modules

Instruments, effects and MIDI tools as editable source to start from.

Pre-made DSP

60 named effects plus filters, oscillators, physical models and voices.

Interface kit

Knobs, keyboards, pads, meters and visualizers bound to parameters.

Generative audio

Sounds, kits, stems and MIDI. Maru runs the models; your users generate on their own account.

Agent tools

A skill, a CLI and MCP servers, so any agent works on a real project.

Licensing and checkout

Trials, seats, refunds and testers, with no licensing code.
