I’m waiting aswell for MIDI 2.0 support. I think it’s because Microsoft, they should’ve had it finished by end 2023. Their roadmap says: second dev preview by October 2023, 1.0 by end of 2023. We are almost mid 2024 and still on dev preview 5.
Edit: dev preview 5 is from 7th March and in that release they say they are moving to production, so hopefully it should be ready “soon”?
Windows MIDI Services will be rolling out through Insider Builds over the next months, starting in November, to both Intel/AMD x64 and Arm64 PCs, with increasingly more consumer-ready releases. We’ll start with the more technical customers and development partners on our Discord Server and will expand as we find and fix issues. Then, once we and our customers and partners are satisfied with the compatibility and quality, we’ll switch it on by default, and roll it out broadly to retail Windows customers.
