ktmidi 0.10.0 release(s)

[atsushieno]

Today I tagged and released ktmidi 0.10.0 (not 1.0.0).

LibreMidiAccess

This version introduced the new MidiAccess driver: LibreMidiAccess (via libremidi-javacpp). It makes use of libremidi and brings in MIDI 2.0 UMP port features on MacOS, Linux, and probably Windows if it is built with Windows MIDI Services via Kotlin/JVM.

LibreMidiAccess also supports virtual MIDI ports, including those for UMP. If libremidi over Windows MIDI Services works, then they would work on Windows too.

With LibreMidiAccess, ktmidi-ci-tool now works over UMP (confirmed on Linux and MacOS).

(There could be Kotlin/Native support too, but that has not realized yet.)

Things may not work perfectly yet, but we'll get fixes over those v0.10.x series.

MergedMidiAccess

There is now a new utility MidiAccess implementation called MergedMidiAccess which merges more than one MidiAccess implementations as one MidiAccess.

Along with this utility, there is now canCreateVirtualPort(context) function that takes PortCreatorContext, instead of canCreateVirtualPort property. It is to filter out any of such a MidiAccess items in a MergedMidiAccess that do not support UMP (or MIDI1) ports.
