"USB-IF is proud to support the MMA and AMEI by publishing an updated USB Device Class Specification for next-generation MIDI devices,” says Jeff Ravencraft, USB-IF President and COO. “USB has been an integral part of the MIDI environment over the past 20 years, and we look forward to seeing innovative new devices that are enabled by this updated specification."
Mike Kent, Project Chair of the USB MIDI class specification and Chairman of the MMA's MIDI 2.0 Working Group, said, "This updated specification delivers many improvements that musicians and artists want from MIDI 2.0, including bidirectional communication, higher-speed throughput, more MIDI channels, accurate timing with dense MIDI streams, and backwards compatibility with MIDI 1.0 devices. The USB-IF's work is a major, and significant, step forward for MIDI 2.0."
The original USB Device Class Specification supporting MIDI 1.0 devices was published in 1999. Since then, USB MIDI has grown significantly and is now the most widely used transport for MIDI. The updated specification uses the new Universal MIDI Packet format over USB, and is designed to cover the widest range possible of MIDI applications and products. This USB specification is a key enabler for MIDI 2.0, supporting the inspiring features of MIDI 2.0 devices while integrating backward support for MIDI 1.0 devices.
Companies contributing to the updated specification include Apple Corporation, Knowles Corporation, Native Instruments, Roland Corporation, and Yamaha Corporation.
