MIDIConnectionEvent

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The MIDIConnectionEvent interface of the Web MIDI API is the event passed to the onstatechange event of the MIDIAccess interface and the onstatechange event of the MIDIPorts interface. This occurs any time a new port becomes available, or when a previously available port becomes unavailable. For example, this event is fired whenever a MIDI device is either plugged in to or unplugged from a computer.  

Constructor

Creates a new MIDIConnectionEvent object.

Properties
