Hello I'm a member of the (Coalition for Content Provenance and Authenticity) C2PA's Audio Working Group. 

The group is actively working on including MIDI 2.0 in the C2PA specifications.

In our implementation of adding C2PA to MIDI 2.0 we would need a Manufacturer ID (SysEx ID) so we could indicate the data is a C2PA manifest and thus could be verified.

I personally was just wondering about the best way to discuss this with the MIDI 2.0 group.

I know I can pay for a membership, and many of the organization in C2PA are already corporate members, but since the Manufacture ID (SysEx ID) would have to be shared with people inside our group and outside, it might warrant a discussion.
