Note App

Outdated Documentation

This app is different in Matrix OS 3.0, but the documentation has not been updated to reflect that.

The Note App serves as a MIDI note interface, allowing users to play MIDI notes with various layouts, scales, and modes.

Upon launching, you will enter the note pad. Click the function key to access the config menu, and click again to return to the note pad.

To exit the Note App, enter the config menu and hold down the function key. This will return you to the application launcher.

Note Pad

The Note Pad is the main view of the Note App. It displays the current note pad with the selected layout, scale, and mode.

The appearance of the pad will vary depending on the customization options. Refer to Example Layouts to see how the notepad looks with different settings.

Clicking the function key will bring you to the config menu.
