It'll append F7 bytes to the end of SysEx messages only - not the usual
control messages.

If you don't want to talk MIDI, you probably shouldn't be using MIDI Manager.

I don't know about that. Messages are either MIDI data or meta-messages
(e.g. transmission/reception errors). If you want all kinds of extensibility,
then you aren't talking MIDI anymore and, as I said, you probably don't
want to use MIDI Manager.
