30 years ago at the 1983 Winter National Association of Music Merchants (NAMM) trade show, a Roland JX-3P talked to a Sequential Circuits Prophet 600 and Musical Instrument Digital Interface (MIDI) went mainstream. The MIDI Manufacturers Association (MMA) will kick off a yearlong "MIDI Makes Music" 30th Anniversary celebration at this year's NAMM Show, with an exhibit showcasing the past, present and future of MIDI technology and an extensive traditional and social media presence showing how famous artists and musicians everywhere use MIDI to create and produce music.
