SpaceWalk - Chord Generator

The SpaceWalk harmonic engine is now on iPad, providing AUv3 Instrument and MIDI FX versions for generating evolving progressions inside your host.

SpaceWalk is a generative harmony engine that creates continuously evolving chord progressions in real time. Unlike tools that cycle through preset sequences, SpaceWalk composes on the fly — its four-voice engine selects chords, voicings, movement and timing dynamically, producing smooth, musical progressions that drift and develop naturally.

Use SpaceWalk as an AUv3 Instrument routed through to an instrument of your choice to generate harmonic pads directly on your iPad, or insert the MIDI FX version before any synth or sampler to drive your favourite sounds with evolving progressions. It follows your host's tempo, transport and looping, and all state is saved within your project. Export your progressions as standard MIDI files for further editing and arrangement in any DAW.

SpaceWalk is ideal for ambient producers, soundtrack composers, sound designers, and anyone who wants inspiration or movement without repetitive patterns. You can record the generated MIDI into your DAW, edit it freely, arrange it, or layer it with other instruments.

Designed specifically for iPad, SpaceWalk works in Logic Pro for iPad, AUM, Cubasis and any AUv3-compatible host. The interface is optimised for touch and supports multiple instances in a single project.

Important: SpaceWalk generates MIDI data, not audio. To hear your progressions, SpaceWalk's MIDI output must be routed to an instrument — this requires a host that supports inter-track MIDI routing. Some hosts, such as GarageBand, do not support this. In GarageBand or the standalone SpaceWalk app, you can still generate and export progressions as MIDI files, but you will not hear audio output.

Whether you want atmospheric beds, slow harmonic motion, or a creative spark when you're stuck, SpaceWalk gives you a fluid, evolving foundation for your music.
