Back to the User Interface Reference page
The main menu is the "root" of the UI. From here you can reach anything.
Opens Simple mode.
Opens MIDI Live mode.
Opens Lightsaber mode.
Shows you the Help and Info page
Opens the Settings.
Brings you back to the Log In page. In case you have auto log in set up, this will be disabled now. Otherwise it wouldn't be possible to actually switch the user.
There are no sysex commands for this specific page. However, only when you're viewing this page (or the startup screen), the on-screen data will be updated when receiving sysex commands. If you're f.ex. on the Simple mode page, Syntherrupter will still react and apply all sysex commands, but the values on screen won't follow these changes.
