Simple MIDI

Simple MIDI is a library for parsing byte streams of MIDI and emit MIDI events.

• Simple event based interface
• Handles running status
• Handles system real-time messages

Example

The example program reads MIDI data on stdin and outputs a textual representation of some MIDI events. Pipe a MIDI stream into it to use as a simple MIDI monitor.

./example </dev/midi1

Handling SYSEX

System exclusive messages was not made a special case in the parser and system exclusive data works as though it was a single-data byte status; MIDI_SYSEX will not be emitted until the first following data byte (vendor ID) appears, and each following data byte will appear as a MIDI_SYSEX event, until interrupted by another status (normally EOX, end of SysEx).

Note off events

This library makes no effort to hide the fact that some vendors use note-on events with velocity 0 instead of note-off. This is allowed by the MIDI 1.0 specification.
