Anyone who commercially designs or manufacturers MIDI hardware,
software or content may join MMA and participate in developing
interoperability standards through email discussions, teleconferences,
and/or physical meetings.
The MMA produces and publishes the MIDI 1.0 and all other
industry-adopted specifications for and related to MIDI. Some
documents are available online, while others are available only in
print (and can be purchased here).
The MMA assigns unique MIDI ID numbers to manufacturers in order to
prevent conflicts. MIDI ID
holders are listed on the MMA Web Site.
- The Manufacturer's MIDI System Exclusive ID number
provides each manufacturer with a way to communicate product-specific
data via MIDI. Companies that are not Regular Members pay a small annual fee as long as they
manufacture products that use the MIDI ID. The fee is includes in the
annual membership for Regular Members.
- The DLS Proprietary Chunk ID provides each manufacturer
a way to embed custom product information into a standard DLS file.
- Information about XMF Resource IDs can be found here.
MMA displays member company logos (or other marketing images) in
rotation on the MMA Home Page. Member and non-member companies may
submit product announcements, press releases, etc., to MMA for
distribution to MIDI enthusiasts via the "MMA Announcements"
MIDI/Audio Jobs Board
Anyone looking for work in this industry, or interested in hiring
people skilled in MIDI or other audio related disciplines is welcome
to use our MIDI/Audio Jobs Board.
Public Web Forum
The MMA hosts a Web Bulletin
Board for public
discussions and questions about MIDI technology and MIDI products.
Members have access to representatives at other member companies, for the purpose of
compatibility testing, trade show loaners, etc. Meetings and social events are held in
conjunction with various industry-related trade shows (e.g. NAMM, AES, GDC, etc.) to
provide additional opportunities for contact with peers.
The MMA maintains strategic relationships with other organizations to assist and
promote the use of MIDI technology in new areas.
- IEC-TC100: TC100 manages a large number of standardization
projects related to Audio/Visual products and systems. The TC100
work is divided into "technical areas", and our liaison relationship
with TC100 allows MMA members (upon approval of the MMA Executive
Board) to participate in TC100 TA meetings and contribute to
relevant TC100 projects.
- ISO/IEC-JTC1-SC29 (MPEG): MIDI is one of the "synthetic audio" formats in
MPEG-4, and DLS2 is the MPEG-4 Sound Bank Format. Through our liaison relationship
with MPEG, MMA members may participate in MPEG (WG11) meetings
and work projects upon approval of the MMA Executive Board.
1394TA: MMA Recommended Practice RP-027 was
developed cooperatively with the 1394TA, and is the approved means for transmitting
MIDI over IEEE-1394.
AES: MMA monitors activities in SC-02-12 and cooperates on
development of professional audio networking solutions.
3GPP: MMA's SP-MIDI and Mobile DLS/XMF
technologies have been adopted by 3GPP for ringtones and other audio use on mobile
CEA: The CEA runs the International Consumer Electronics
Show, and MMA participates in the Allied Association program and
various technical and marketing summits.
IETF: MMA provided formal review for IETF of "RTP-MIDI"
(RTP Payload Format for MIDI)
IEEE: MMA has cooperated in the development of the IEEE-1722
Transport Protocols for Time-sensitive Streams.
W3C: MMA is cooperating with W3C to
enable MIDI I/O in browsers.
