Button

This creates a button in the top panel of the screen, which can be used to trigger various MIDI events. The button can either be used to start MIDI notes when it is pressed down (either fixed notes or chords, or depending on what notes are currently active from the notesi> input port), or send Control Change (for example enable the Sustain pedal while the button is down) or Program Change events.

The button can also act like a toggle, which will be activated when it is pressed, and deactivate again when it is pressed again.

Ports:

This is used for the "notes from input port" setting. The currently active notes from this port are passed on if the button is pressed if "notes from input port" is selected.

The generated MIDI events are sent out of this port.

Settings:

Show custom title: By default, the button shows the name of the action that will be triggered by it. If you prefer to use your own title on the button, you can enable this here and change the title.

Action: This will open up the settings of the action that will be triggered on button presses.
