Updated MIDI 2.0 Specifications Now Available


After three years of intensive prototyping and many virtual and face to face meetings, The Association of Musical Electronics Industry (AMEI) and The MIDI Association have published 4 significantly updated MIDI 2.0 core specifications and a brand new specification for a MIDI 2.0 SMF Clip File.

These are the result of many ‘man years ‘of volunteer work by members of AMEI and The MIDI Association and consist of over 350 pages of detailed specifications.

These core specifications define the architectural foundations for MIDI 2.0 and define minimum requirements for devices to claim MIDI 2.0 compatibility and use the MIDI Association’s MIDI 2.0 logo.

AMEI and The MIDI Association have provided the specifications for free download, but you have to register first:

With this updated MIDI 2.0 spec, plans are proceeding to open the MIDI Association Github which contains tools and source code under a permissive MIT license to all developers.

This follows public demos of MIDI 2.0 at the April 2023 NAMM show:

  • Roland and Synthogy teamed up to demonstrate MIDI 2.0 High Resolution Velocity using an Apple computer and the publicly available version of Logic.
  • There were working prototypes of both Microsoft and Linux MIDI 2.0 drivers.
  • And Korg, Bome Box and Analog Devices were all showing prototype products that implemented MIDI 2.0.

For more detailed explanations about the updated MIDI spec, see the article “What Musicians and Artists need to know about MIDI 2.0,” on the MIDI Association website.
