MIDIPort: close() method

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The close() method of the MIDIPort interface makes the access to the MIDI device connected to this MIDIPort unavailable.

If the port is successfully closed a new MIDIConnectionEvent is queued to the MIDIPort.onstatechange and MIDIAccess.onstatechange event handlers, and the MIDIPort.connection property is changed to "closed".

Syntax

Parameters

None.

Return value

Returns a Promise which resolves once the port has been closed.

Examples

The following example shows an output port being closed.
