Some attached devices might be professional lighting control systems, so it’s possible you could control stage lighting; however, this is extremely rare, and no known system has the ability to cause lasting damage or information leakage based solely on short messages; at worst, a malicious page could flash lights, and the user could close the page and reset their lighting controller. enables MIDI applications to ensure other applications can gain access If the user gives express permission or the call is otherwise requestMIDIAccess(opts = {}): Promise opts.sysex: boolean; createMIDIDevice(opts = {}): MIDIDevice. when a previously-available port becomes unavailable, or becomes This document is governed by the 1 August 2014 W3C Process Document. handler of the MIDIPort.
