MidiProto

See MidiProto.Parser for information about parsing incoming MIDI messages into data structures.

See MidiProto.Message for information about messages and encoding them into the wire.

Examples

Generating a note-on message for middle C and encoding it for transmission:

iex> MidiProto.Message.NoteOn.init(0, 60, 127)
...> |> MidiProto.Message.encode()
<<0x90, 0x3c, 0x7f>>

Parsing an incoming packets:

iex> MidiProto.Parser.init()
...> |> MidiProto.Parser.append(<<0x90, 0x3c, 0x7f>>)
...> |> MidiProto.Parser.parse()
{:ok, [%MidiProto.Message.NoteOn{channel: 0, note_number: 60, velocity: 127}], %MidiProto.Parser{}}

Generating a Firmata message:

iex> MidiProto.Firmata.FirmwareQuery.init()
...> |> MidiProto.Message.encode()
<<0xf0, 0x79, 0xf7>>

Converting a MIDI message into a Firmata message:

iex> MidiProto.Message.SystemExclusive.init(0x79, "")
...> |> MidiProto.Firmata.convert()
{:ok, %MidiProto.Firmata.FirmwareQuery{}}
