The MIDI Association website is administrated by the MMA, the non-profit trade association of companies who develop products that use MIDI technology. The MMA is responsible for the development, promotion, and protection of MIDI technology. The efforts of the MMA to promote and expand MIDI’s reach are one reason that MIDI remains one of the most relevant standards in the entertainment industry. MMA members include platform/OS developers (such as Apple, Google and Microsoft) and musical instrument makers (such as Nectar, Roland, Roli and Yamaha) and music software publishers (such as Ableton, Steinberg, Mark of the Unicorn, and Make Music). Membership in the MMA is open to anyone that commercially designs, develops, or produces products that use MIDI technology.
