Fixes (Machinedrum)
- Unsaved kit edits are no longer lost when you click a step elsewhere.
- Kit values always reach the machine: undo after Control All is heard, and a value set right after a machine change stays.
- "Set up sampling" sets the recorder's volume to 0, so the recorder never records itself (no feedback loop).
macOS
- Each machine also comes as a drag-and-drop disk image (.dmg), next to the installer (.pkg).
- The editors have their own bundle identifiers and settings files, apart from upstream Gearmulator. Settings from 0.3.0 and earlier are copied over on first start.
- The release pipeline is ready for Developer ID signing and notarization.
Install
Bring your own ROM: nothing is bundled. If macOS says the app cannot be opened, go to System Settings › Privacy & Security and click Open Anyway.
