+<p>This specification defines a data type for a MIDI message, midi:MidiEvent,

+controlling digital music devices.</p>
+
+<p>For plugins that process MIDI (or other situations where MIDI is sent via a
+generic transport) the main type defined here, midi:MidiEvent, can be mapped to
+an integer and used as the type of an LV2 <a
+href="../atom/atom.html#Atom">Atom</a> or <a
+href="../event/event.html#Event">Event</a>.</p>
+
+<p>This specification also defines a complete human and machine readable
+description of the MIDI standard (except for standard controller numbers).
+These descriptions are detailed enough to express any MIDI message as

+ <li>Running status is not allowed, every message must have its own status
+ byte.</li>
+
+ <li>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
