Android 13 Developer Preview 2 by Dave Burke
MIDI 2.0 - Android 13 adds support for the new MIDI 2.0 standard, including the ability to connect MIDI 2.0 hardware through USB. This updated standard offers features such as increased resolution for controllers, better support for non-Western intonation, and more expressive performance using per-note controllers.
Still wondering , does Android 14 implement UMP 1.1.1 ? 13 only implements up to UMP 1.0. 15 appears to implement virtual MIDI ports. Nothing about UMP 1.1.1
Virtual MIDI 2.0 Devices
Android 13 added support for connecting to MIDI 2.0 devices via USB, which communicate using Universal MIDI Packets (UMP). Android 15 extends UMP support to virtual MIDI apps. This enables composition apps to control synthesizer apps as a virtual MIDI 2.0 device, just like they would with a USB MIDI 2.0 device.
Android 13 Developer Preview 2 introduces support for MIDI 2.0, enhancing MIDI capabilities with improved features and performance for music applications.
