A modern, free and open-source patch editor for the Clavia Nord Modular G2, made for macOS on Apple silicon.
Cube G2 Editor keeps the familiar layout and workflow of the original G2 editor, so patches look and behave the way G2 players know them, and runs natively on current Macs.
Public beta 0.1.4. It is developed and tested on a real G2, but it is still beta software that sends patches to your synth. Back up your banks first (Synth ▸ Download Banks from G2…).
This is an early beta. Please try everything you do with your G2 and report what doesn't work, looks wrong or feels awkward — see Feedback and bug reports.

What changed in each version: release notes (also in the app, under Settings ▸ Updates).
Requirements:
- macOS 15 Sequoia or later
- A Mac with Apple silicon (M1 or newer). Intel Macs are not supported.
- Nord Modular G2 with OS 1.62, connected over USB. The G2X and G2 Engine have not been tested yet.
- Open the
.dmgfile and drag Cube G2 Editor to Applications. - Open the app. macOS says it can't check the app for malware. Click Done.
- Open System Settings ▸ Privacy & Security, scroll down and click Open Anyway.
You only need to do this once for every new version. Your settings and patches stay when you update.
Why? Cube G2 Editor is an independent app that isn't registered with Apple, so macOS can't verify it automatically. This is common for free, independent software.
The editor checks GitHub for new versions once a day (Settings ▸ Updates). It only tells you; it never downloads or installs anything by itself.
- Opens, edits and saves G2 patches (
.pch2) and performances (.prf2). - Edits the patch on the G2 live over USB: modules, cables, knobs, names and colors.
- Four slots and performances, variations, morphs, parameter pages and the global knobs.
- Module library with previews, cable chains, keyboard shortcuts.
- Patch Mutator and Patch Adjuster for exploring new sounds.
- Spectrum and X-Y plot from your audio interface inputs.
- Backup of the G2's memory banks to your Mac.
- On-screen keyboard to play the selected slot.
The beta lives on the Cube G2 Discord: https://discord.gg/2kUhfYRa2t.

Settings ▸ Feedback in the app lists what to include and shows how to save a USB log.
