To find out when the available MIDI devices change, call MidiDeviceListConnection::make(), passing a lambda that will be called on each configuration change.
To stop the lambda receiving callbacks, destroy the MidiDeviceListConnection instance returned from make(), or call reset() on it.

If this object had an active connection, that connection will be deactivated, and the corresponding callback will be removed from the MidiDeviceListConnectionBroadcaster.

Registers a function to be called whenever the midi device list changes.
The callback will only be active for as long as the return MidiDeviceListConnection remains alive. To stop receiving device change notifications, destroy the Connection object, e.g. by allowing it to fall out of scope.
