I’m confused by the OWL’s MIDI Sysex Manufacturer ID: It is listed in the ‘MIDI Mappings’ file as ‘0x7D’ - but I thought this was an internal R&D (non-commercial) ID that can’t be used for any product released to the public.
Yes we’re not members of the MIDI association ($$$) so we don’t have an official Manufacturer ID.
The way that the OWL is used, with a direct USB MIDI connection, means there’s very little risk of it receiving unintended SysEx messages. With USB MIDI you just don’t have chains of devices as you do with traditional, 5-pin DIN MIDI.
We do have a unique USB Vendor and product ID 
OK. Interesting. Hadn’t thought of it that way before.
