Can send individual MIDI/OSC messages when a button is turned on, superseded and turned off. Can additionally send a MIDI/OSC message when ANY button is turned on or off. Messages and target connections (per message) can be set in the script.
To understand which messages are sent in which situation try the OSC version of the multitoggles as the demo OSC messages contain "on / super(seded) / off" which is easier to follow than with cryptic MIDI messages.
Look at the scripts for further explanations.
