Struct rimd::MidiMessage

pub struct MidiMessage {
    pub data: Vec<u8>,
}

Midi message building and parsing. See http://www.midi.org/techspecs/midimessages.php for a description of the various Midi messages that exist.

Fields

data: Vec<u8>

Methods

impl MidiMessage

fn status(&self) -> Status

Return the status (type) of this message

fn channel(&self) -> u8

Return the channel this message is on (TODO: return 0 for messages with no channel)

fn data(&self, index: usize) -> u8

Get te data at index index from this message. Status is at index 0

fn from_bytes(bytes: Vec<u8>) -> MidiMessage

Create a midi message from a vector of bytes

fn next_message_given_status(
    stat: u8,
    reader: &mut Read
) -> Result<MidiMessage, MidiError>

Get the next midi message from the reader given that the status stat has just been read

fn next_message_running_status(
    stat: u8,
    databyte: u8,
    reader: &mut Read
) -> Result<MidiMessage, MidiError>

Get the next midi message from the reader given that there's a running status of stat and that in place of a status was read databyte

fn next_message(reader: &mut Read) -> Result<MidiMessage, MidiError>

Extract next midi message from a reader

fn note_on(note: u8, velocity: u8, channel: u8) -> MidiMessage

Create a note on message

fn note_off(note: u8, velocity: u8, channel: u8) -> MidiMessage

Create a note off message

fn polyphonic_aftertouch(note: u8, pressure: u8, channel: u8) -> MidiMessage

Create a polyphonic aftertouch message This message is most often sent by pressing down on the key after it "bottoms out".

fn control_change(controler: u8, data: u8, channel: u8) -> MidiMessage

Create a control change message This message is sent when a controller value changes. Controllers include devices such as pedals and levers. Controller numbers 120-127 are reserved as "Channel Mode Messages".

fn program_change(program: u8, channel: u8) -> MidiMessage

Create a program change message This message sent when the patch number changes. program is the new program number.

fn channel_aftertouch(pressure: u8, channel: u8) -> MidiMessage

Create a channel aftertouch This message is most often sent by pressing down on the key after it "bottoms out". This message is different from polyphonic after-touch. Use this message to send the single greatest pressure value (of all the current depressed keys). pressure is the pressure value.

fn pitch_bend(lsb: u8, msb: u8, channel: u8) -> MidiMessage

Create a pitch bench message This message is sent to indicate a change in the pitch bender (wheel or lever, typically). The pitch bender is measured by a fourteen bit value. Center (no pitch change) is 2000H. Sensitivity is a function of the transmitter. lsb are the least significant 7 bits. msb are the most significant 7 bits.
