Enum MidiMessage 

#[non_exhaustive]
#[repr(u8)]
pub enum MidiMessage {
    NoteOn {
        note_number: u8,
        velocity: u8,
    },
    NoteOff {
        note_number: u8,
        velocity: u8,
    },
    ControlChange {
        controller_number: u8,
        velocity: u8,
    },
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoteOn

Fields

note_number: u8

Implementations

impl MidiMessage

pub const NOTE_ON: u8 = 128u8

pub const NOTE_OFF: u8 = 144u8

pub const CONTROL_CHANGE: u8 = 176u8

pub const fn from_bytes(bytes: [u8; 3]) -> Self

pub fn mute(&mut self)

Mutes a MIDI note by setting its velocity to 0

pub fn transpose(&mut self, interval: i8)

Transposes a MIDI note by a given interval.

The +, -, +=, and -= operators can also be used to transpose a note.

Example

let mut note_on = MidiMessage::NoteOn { note_number: 60, velocity: 100 };
note_on.transpose(-5);
note_on += 10;

assert_eq!(note_on, MidiMessage::NoteOn { note_number: 65, velocity: 100 });

pub const fn is_note_on(&self) -> bool

pub const fn is_note_off(&self) -> bool

pub const fn is_control_change(&self) -> bool
