Arduino Midi

Posted on Feb 6, 2014

MIDI, the Musical Instrument Digital Interface, is a useful protocol for controlling synthesizers, sequencers, and other musical devices. MIDI devices are generally grouped in to two broad classes: controllers (i. e. devices that generate MIDI signals based on human actions) and synthesizers (including samplers, sequencers, and so forth).

er take MIDI data in and make sound, light, or some other effect. MIDI is a serial protocol that operates at 31, 250 bits per second. The Arduino`s built-in serial port (all of them on the Mega as well) can send data at that rate. MIDI bytes are divided into two types: command bytes and data bytes. Command bytes are always 128 or greater, or 0x80 to 0xFF in hexadecimal. Data bytes are always less than 127, or 0x00 to 0x7F in hex. Commands include things such as note on, note off, pitch bend, and so forth. Data bytes include things like the pitch of the note to play, the velocity, or loudness of the note, and amount of pitch bend, and so forth. For more details, see the MIDI specification, or one of the many MIDI Protocol Guides on the Web.
