All four apps are free through 13 September 2026

Music tools built for Ableton Live. The feel of hardware in a software format. Let's jam.

Mac apps built around the parts of a session software usually leaves you to do by hand: mutating a bassline into a couple of variations, triggering chords from single keys, seeing what you're actually hearing, and deciding what a knob does. Built for Ableton Live, compatible with any DAW.

The four apps open at once, cascaded: MutationStation in front, then Chordinator, Spectrl and MidiMirror behind it

MutationStation · macOS app

MutationStation icon

MutationStation

Lock the notes that work, re-roll/mutate the rest, and discover acid lines you would not have usually written.

Give it a line and it mutates it across pitch, rhythm, accent, slide, octave and length into fresh variations you can audition, edit and drag straight into your DAW. Lock the notes that already work, Elektron-style, and re-roll everything else as often as you like. Or concentrate the mutation to a marked specific section of your sequence. Play notes in from a keyboard or a DAW track, pull a clip from Ableton Live and push it back out, and draw up to eight modulation lanes that stream live or bake into a Session clip as automation.

Chordinator · macOS app

Chordinator icon

Chordinator

128 chords under one keybed, and a chord generator to help you pick or follow the tonic of your bass line.

A whole chord under one key, laid out so there is no wrong note on the keybed, with 84 harmony engines and live suggestions for where to go next. Build it out with a poly piano roll, a rhythm generator measured from real dub house and dub techno records, groove and humanize passes, and eight modulation lanes landing in Live as clip envelopes.

Spectrl · macOS app

Spectrl icon

Spectrl

Spectrum, key detection, note frequencies, tonal balance and a system-audio sampler in one window.

Six tools reading one signal: live spectrum with musical note mapping, a Scale panel that listens for ten seconds and names the key, loudness metering, an oscilloscope, tonal-balance targets and a system audio sampler. It taps your output through Core Audio, so it hears your DAW without a plugin on the master, and records straight to WAV with nothing to route.

MidiMirror · macOS app

MidiMirror icon

MidiMirror

A mirror for your hardware MIDI controller: see the exact values of your knobs, and customise what each one does.

Decide what every knob, fader and key reaches in Ableton Live, then generate a real Remote Script for your controller. Custom modes, two jobs on one key, a drop that snaps the whole panel back, and a second-screen mirror that labels every control as it moves. Run two controllers for a window each; switch to JamWare mode and the panel becomes Chordinator's or MutationStation's front panel, already labelled.

Bundles

The Creative Bundle

MutationStation and Chordinator, the two apps that write notes. They were built to be used together: take chords from Chordinator, mutate a line against them in MutationStation, and drag either one straight into your DAW.

The Toolbox Bundle

Spectrl and MidiMirror, the tools that handle the session around the notes. See what you are actually hearing, and decide what every knob on your controller reaches.

What you get

Licence · updates · refunds

Three machines. One purchase covers up to three Macs. Moving to a new machine does not cost anything: delete the old activation code and generate a fresh one for the new Mac.

Updates, your way. Every app can check for updates on its own and tell you when one is ready, or stay quiet and leave it to you to check by hand. Set it whichever way you prefer in the app.

14 days trial, no questions asked. Refunds follow EU consumer law: if it is not for you, ask within 14 days of purchase and you get your money back. You don't have to fill in a form or give a reason.

Standalone, not a plugin

Why standalone?

The standalones plug into Ableton Live the way a plugin does, but from the outside. Each one runs as its own Mac app and reaches your set over a virtual MIDI port, the same route any outboard hardware uses (for MidiMirror, through a real Remote Script it writes into Live). You get the immediacy of a plugin, picking it as a MIDI source and playing, without living inside the DAW's process. That separation works in your favour: if Live crashes, the app and whatever you were building in it are untouched, and if the app crashes, your project stays unbothered.

About

Built to be used

These tools were built with the purpose of actually making music. I built each one because I needed it in my own sessions, before sharing them for a little fee crossed my mind. I won't create devices that are doing something that already exists without adding any additional new benefit.
