High Definition Protocol HDWG)
The concept of a High-Definition protocol comparable to MIDI is now being
discussed. This would provide greater resolution in data
values, increase the number of Channels, and allow for the creation of
entirely new kinds of messages that will encourage future
innovation.
Transport Layer (TLWG)
The TLWG makes recommendations and produces specifications for alternate
transports for MIDI protocol (other than the transport defined in the current
MIDI 1.0 Detailed Specification). TLWG objectives are to insure continued
high-quality performance, maximum interoperability, and consumer satisfaction
with MIDI. The group does not have any projects at this time.
Downloadable Sounds (DLSWG)
This group assisted MPEG in harmonizing the industry standard DLS format with
the Sound Fonts format (E-mu Systems/Creative Labs) for MPEG-4, and produced
updates to DLS 2.1 to align it with MWG's Mobile DLS Specification.
The group does not have any projects at this time.
Mobile (MWG)
The MMA's Mobile Working Group created the SP-MIDI Specification and
the 5-to-24 Note Profile for 3GPP which has been adopted for 3rd generation
mobile phones, and completed Mobile DLS/XMF for mobile phones. Recent projects
include ID3 Tags and Audio Clips for Mobile XMF. The group does not
have any projects at this time.
XMF (XMFWG)
The MMA's Extensible Music File (XMF) format encapsulates Standard MIDI Files
with DLS and other content for synchronized playback and file interchange. The
XMFWG supervised work on the XMF formats developed in MWG, and is
currently supervising the iXMF project in IASIG.
XML (XMLWG)
This group works on enhancements and documentation
for the MMA's XML Specification of MIDI events, names, and device features.
The group produced the MIDI-XML DTDs and is expected to complete the
written Specifications.
