This specification defines a data type for a MIDI message, midi:MidiEvent,
which is normalised for fast and convenient real-time processing. MIDI is the
Musical Instrument Digital Interface
, a ubiquitous binary standard for
controlling digital music devices.
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 Atom or Event.
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 properties.

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:
If a midi:MidiEvent is serialised to a string, the format should be xsd:hexBinary, e.g. (in Turtle notation):
[] eg:someEvent "901A01"^^midi:MidiEvent .

OWL Type | Datatype Property |

Range | xsd:short |
The MIDI event to bind a parameter to. This describes which MIDI events should be used to control a port, parameter, or other object. The binding should be a midi:MidiEvent but the property that represents the control value may be ommitted. For example, to bind to the value of controller 17:
port midi:binding [ a midi:Controller ; midi:controllerNumber 17 ] .
