In 2006, the Dutch company Kiss-Box presented a first embedded implementation of RTP-MIDI, in different products like MIDI or LTC interfaces. The RTP-MIDI driver from Apple creates virtual MIDI ports named 'Sessions', which are available as MIDI ports in any software, such as sequencers or software instruments, using CoreMIDI, where they appear as a pair of MIDI IN / MIDI OUT ports like any other MIDI 1.0 port or USB MIDI port. However, it is possible to manually enter IP addresses and ports in this directory to connect to devices which do not support Bonjour.Īpple also introduced RTP-MIDI support in iOS4, but such devices cannot be session initiators. Devices which comply with this class appear automatically in Apple's RTP-MIDI configuration panel as the Participants directory, making the Apple MIDI system fully ' Plug & Play'. This protocol is displayed in Wireshark as 'AppleMIDI' and was later documented by Apple.Īpple also created a dedicated class in their mDNS/ Bonjour implementation. Apple's implementation strictly follows the RFC 4695 for RTP payload and journalling system, but uses a dedicated session management protocol they do not follow the RFC 4695 session management proposal. The RTP-MIDI driver is reached using the Network icon in the MIDI/Audio Configuration tool. AppleMIDI Īpple Computer introduced RTP-MIDI as a part of their operating system, Mac OS X v10.4, in 2005.

The MMA ( MIDI Manufacturers Association) has created a page on its website in order to provide basic information related to RTP-MIDI protocol. The protocol has not changed between the two version of the RFC documents, the last one contains correction of errors found in RFC 4695) RFC 4695 has been obsoleted by RFC 6295 in 2011. In parallel, another document was released by Lazzaro and Wawrzynek to give details about practical implementation of the RTP-MIDI protocol, especially the journaling mechanism.

In 2006, the document was submitted to IETF and received the number RFC 4695. In 2004, John Lazzaro and John Wawrzynek, from UC Berkeley, made a presentation in front of AES named 'An RTP payload for MIDI'. RTP-MIDI is compatible with real-time applications, and supports sample-accurate synchronization for each MIDI message. Compared to MIDI 1.0, RTP-MIDI includes new features like session management, device synchronization and detection of lost packets, with automatic regeneration of lost data. It is completely open and free (no license is needed), and is compatible both with LAN and WAN application fields.

RTP-MIDI (also known as AppleMIDI) is a protocol to transport MIDI messages within Real-time Transport Protocol (RTP) packets over Ethernet and WiFi networks. midi-articles /rtp-midi-or-midi-over-networks ( May 2022) ( Learn how and when to remove this template message) The references used may be made clearer with a different or consistent style of citation and footnoting.
