A MIDI input parser is unnecessarily reset whenever a new subscription
is created.
This is a particular problem with the Novation Launchpad, which sends a
single NOTEON command, then a series of notes indefinitely unless a
control button is pressed or it is power cycled. If a user application
restarts and resubscribes, the parser no longer knows that it is
receiving NOTEONs and fails to pass on new input.
