Old CoreMIDI APIs are missing

[mandel-macaque]

The following CoreMIDI APIs ere not reported as not bound on Mac OS X. A new change in xtro reports them but we should consider if binding them needs to be done, since some of them are quite low level:

• !missing-pinvoke! MIDIClientCreateWithBlock is not bound Documentation Versions iOS 9.0+ macOS 10.11+
• !missing-pinvoke! MIDIDestinationCreateWithBlock is not bound Documentation Versions iOS 9.0+ macOS 10.11+
• !missing-pinvoke! MIDIDeviceCreate is not bound Documentation Versions iOS 4.2+ macOS 10.0+
• !missing-pinvoke! MIDIDeviceDispose is not bound Documentation Versions iOS 4.2+ macOS 10.3+
• !missing-pinvoke! MIDIDeviceRemoveEntity is not bound Documentation Versions iOS 4.2+ macOS 10.1+
• !missing-pinvoke! MIDIDriverEnableMonitoring is not bound Documentation Versions macOS 10.1+
• !missing-pinvoke! MIDIEntityAddOrRemoveEndpoints is not bound Documentation Versions iOS 4.2+ macOS 10.2+
• !missing-pinvoke! MIDIExternalDeviceCreate is not bound Documentation Versions iOS 4.2+ macOS 10.1+

• !missing-pinvoke! MIDIInputPortCreateWithBlock is not bound Documentation Versions iOS 9.0+ macOS 10.11+
• !missing-pinvoke! MIDIPacketListAdd is not bound Documentation Versions iOS 4.2+ macOS 10.0+
• !missing-pinvoke! MIDIPacketListInit is not bound Documentation Versions iOS 4.2+ macOS 10.0+
• !missing-pinvoke! MIDISendSysex is not bound Documentation Versions iOS 4.2+ macOS 10.0+

• !missing-pinvoke! MIDISetupRemoveExternalDevice is not bound Documentation Versions iOS 4.2+ macOS 10.1+

New ones that have been added in Xcode 12 beta 2:

• !missing-pinvoke! MIDIDestinationCreateWithProtocol is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDIDeviceNewEntity is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDIEventListAdd is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDIEventListInit is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDIInputPortCreateWithProtocol is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDIReceivedEventList is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDISendEventList is not bound Versions iOS 14.0+ macOS 10.16+
• !missing-pinvoke! MIDISourceCreateWithProtocol is not bound Versions iOS 14.0+ macOS 10.16+

@mandel-macaque some of the newer API should have been bound in xcode12 since they are replacing API that are deprecated - and for which we already have bindings. That does not seem it was the goal of the original issue too...

• MIDIInputPortCreateWithProtocol -> MIDIInputPortCreate
• MIDIDeviceNewEntity -> MIDIDeviceAddEntity
• MIDIReceivedEventList -> MIDIReceived
• MIDISendEventList -> MIDISend
• MIDISourceCreateWithProtocol -> MIDISourceCreate

[mandel-macaque]

Will add those to xcode12.2

[tj-devel709]

Xcode13.3 introduced MIDIEventListForEachEvent that is also low level and cannot be tested without a device so we will not bind for the time being.

• !missing-pinvoke! MIDIEventListForEachEvent is not bound Documentation Versions iOS 15.0+ macOS 13.0+ tvOS 15.0+ watchOS 8.0+ MacCatalyst 15,0+

Any changes in this matter? When will these APIs be added to .NET?

[rolfbjarne]

@chetszot which of the missing CoreMIDI APIs are you interested in? There's been some work on some of the APIs (#22459), but it's been delayed a bit for unrelated reasons, but if you could explain exactly what you're interested in we might fasttrack some of the work.
