This extension defines a data type for a MIDI message, midi:MidiEvent, which +is normalized for fast and convenient processing by plugins. It is +particularly useful as the payload of an Atom or Event.

A single raw MIDI message (i.e. a sequence of bytes).

+ +

This is equivalent to a standard MIDI messages, except with the following +restrictions to simplify handling:

+
    +
  • Running status is not allowed, every message must have its own status + byte.
    • + +
  • Note On messages with velocity 0 are not allowed. These messages are + equivalent to Note Off in standard MIDI streams, but here only proper Note + Off messages are allowed.
    • + +
  • "Realtime messages" (status bytes 0xF8 to 0xFF) are allowed, but may + not occur inside other messages like they can in standard MIDI streams.
    • + +
  • All messages are complete valid MIDI messages. This means, for example, + that only the first byte in each event (the status byte) may have the eighth + bit set, that Note On and Note Off events are always 3 bytes long, etc. + Where messages are communicated, the writer is responsible for writing valid + messages, and the reader may assume that all events are valid.
