About the MMA

About the MIDI Association 

The MIDI Association website is administrated by the MIDI Manufacturers Association which was official established as a California nonprofit, 501(c)6 trade organization) in 1985 with the goal to expand, promote, and protect MIDI technology for the benefit of artists and musicians around the world.

The MMA launched The MIDI Association, a public-facing, free, global, web-based community for people who create music and art with MIDI. Starting with no members at all, four years later, the MIDI Association now has over 30,000 registered individuals.  

The www.MIDI.org website is the central repository of information about all aspects of MIDI technology, from classic legacy gear to the next- gen protocols on the horizon. In May 2020 the United States Library of Congress selected MIDI.org for inclusion in the historic collection of Internet materials related to the Professional Organizations for Performing Arts Web Archive. It’s an honor that they consider the MIDI website to be an important part of this collection and the historical record

The MMA Mission

  • To encourage the use of MIDI technology and MIDI products in established and growth markets.
  • To be proactive in developing and enhancing MIDI to respond to market needs.
  • To insure interoperability of MIDI products through an open standards process with broad industry participation.
  • To protect the meaning of the term MIDI as used in commerce

Specification Development

The MMA is the official source of MIDI technology specifications. Compliance with MMA Specifications and Recommended Practices enables thousands of products from hundreds of companies to interoperate. Companies wishing to take part in the development of new MIDI Specifications must be Regular Members of the MMA and abide by MMA confidentiality and IP policies. All Regular Members receive early access to new Specifications, can contribute to them, and can vote in MMA elections.

Note: As a general policy MMA does not disclose what is being addressed or discussed by our members until consensus has been reached. This policy is necessary because premature disclosure can create market confusion and reduce interoperability. However, some disclosure is necessary for manufacturers/developers to evaluate participating in MMA, so the following is an overview of the topics currently being discussed:

Current Projects (2020):

  • Multiple Profile Specifications
  • Multiple Property Exchange Specifications
  • USB-MIDI 2.0 Updates
  • MIDI 2.0 for AVBTP/Time Sensitive Networks
  • MIDI 2.0 over other transports
  • Standard MIDI File 2.0 Specification

ID Assignment

The MMA assigns unique ID numbers so hardware and software developers can support proprietary features using MIDI technology.

  • The Manufacturer's MIDI System Exclusive ID number provides each hardware or software developer with a way to communicate product-specific data via MIDI protocol (SysEx). Companies pay a small annual fee as long as they produce products that use the MIDI ID (the fee is included in the annual membership dues for Regular MMA Members).

  • The DLS Proprietary Chunk ID and XMF Resource ID each provide developers a way to embed custom product information into a DLS or XMF file.

Marketing and Promotions

The MMA provides numerous promotional opportunities for our members and partners via this website and via events and other activities.

Developer Support

  • Commercial developers of MIDI hardware and/or software may join the MIDI Manufacturers Association and subscribe to mailing lists to discuss issues with other developers.
  • The Forum on this website may be used by anyone with questions about implementing MIDI technology and using MIDI products.
  • The MMA Specifications for using MIDI in an interoperable manner are available to registered users of the website.

Networking Opportunities

In addition to this website, meetings and social events are held in conjunction with various industry-related trade shows (e.g. NAMM, AES, GDC, etc.) to provide opportunities for MIDI developers to connect with peers. (MMA Members also have access to representatives at other member companies, for the purpose of compatibility testing, trade show loaners, etc.)

Liaison Activities

The MMA maintains strategic relationships with other organizations like IEC, CTA, and AES to assist and promote the use of MIDI technology in new areas.
