Yes, I think it would be good if someone from MMA could clarify this. If you think about it, the situation is rather absurd.
In MIDI 1.0, you only needed a Manufacturer ID to define your own SysEx message.
In MIDI 2.0, MMA claims: "To implement MIDI-CI and MIDI 2.0, you need a manufacturers SysEx ID".
There is a maximum of 16.383 unique SysEx IDs. If the MMA claim is correct, everyone on the planet that wants to implement MIDI 2.0 (however simple) needs a SysEx ID. That will (IMO) lead to a situation where all IDs will be occupied, and no additional companies (large or small) can implement MIDI 2.0. And MMA will have annual revenue of $4.259.580, pretty good for a non-profit organization.
This simply can't be the case...
