réactions à la news Les spécifications du MIDI 2.0 sont à présent publiques

The new USB MIDI 2.0 driver will go nearly as fast as the underlying USB port has been negotiated to go and uses an approach similar to WaveRT audio for transferring data.

On the second part, Network MIDI 2.0 was just approved and published as a spec, and I think will ultimately turn out to be more important than the USB transport. I'll have a preview of the Windows implementation at NAMM.

Network MIDI 2.0 to DIN MIDI 1.0 translation boxes will be a thing.

On the first part, we had a lot more work to do than Apple did on this. We rewrote the entire MIDI stack from the ground up, and have also built a very complete solution for MIDI 2.0 while also supporting MIDI 1.0.

Yes, we're behind time-wise, but this month we did start putting the features into Insider builds for partner developer testing.

If not for the backwards compatibility we need to finish (for apps using the old WinMM APIs), we'd be done with 1.0. But we're still finishing up the backwards compatibility work, which has taken quite some time to write. The new API wouldn't be of much use if all the apps using the old one weren't able to be plumbed into the same infrastructure, and able to be multi-client.

At the NAMM Show in January, we’ll have a preview demonstration of the upcoming Network MIDI 2.0 transport standard using Windows MIDI Services. Network MIDI 2.0 is really promising because it enables a different type of connectivity, unencumbered by USB cable length limitations. The Network MIDI 2.0 standard is nearing final review and approval. There are already a number of devices in development which support the upcoming standard, and you’ll be able to use them with Windows.

Supports your Existing Devices. Windows MIDI Services supports the MIDI 1.0 devices you own today, including those with vendor-supplied kernel streaming drivers, as well as class-compliant MIDI 1.0 and MIDI 2.0 devices. The experience will be better/faster if they use the new class driver, but we recognize that is not always possible or desirable with some existing devices.

Supports your Existing Apps. When Windows MIDI Services ships in-box in Windows, the existing WinMM and WinRT MIDI 1.0 APIs will be repointed to the new Windows Service. This will provide a subset of the new features, including multi-client. Those apps will not have access to the user metadata, auto-reconnect, device connect/disconnect detection, rich device details, MIDI 2.0 messages, etc. but will continue to work as today, with the benefit of multi-client (more than one app using the same port) support.
