Channel-level messages that act on a voice. For instance, turning notes on off, or modifying sounding notes. Used in MidiMsg.

Variants

NoteOn

Fields

note: u8

A MIDI note number 0-127. Per GM1, 69 = A440

velocity: u8

The velocity the note should be played at, 0-127

Turn on a note

NoteOff

Fields

note: u8

Stop playing the given MIDI note at this channel, 0-127

velocity: u8

The velocity the note should stop being played at, 0-127

Turn off a note

ControlChange

Fields

control: ControlChange

Generally used for modifying the tones being played. Frequently shortened to ‘CC’

HighResNoteOn

Fields

note: u8

velocity: u16

A note on with a preceding HighResVelocity CC per CA-031

HighResNoteOff

Fields

note: u8

velocity: u16

A note off with a preceding HighResVelocity CC per CA-031

PolyPressure

Fields

note: u8

The note to apply this pressure signal to, 0-127

pressure: u8

The amount of pressure to apply, 0-127

The amount of pressure being applied to a given note, which is a signal some controllers after an initial NoteOn. Can act on multiple notes at a time, thus it is “polyphonic”.

ChannelPressure

Fields

pressure: u8

Similar to PolyPressure, but only applies at the channel-level.

ProgramChange

Fields

program: u8

Which “program”, “patch” or “sound” to use when playing any preceding notes, 0-127. Use GMSoundSet when targeting General MIDI

PitchBend

Fields

bend: u16

Apply a pitch bend to all sounding notes. 0-8191 represent negative bends, 8192 is no bend and8193-16383 are positive bends, with the standard bend rang being +/-2 semitones per GM2. See Parameter::PitchBendSensitivity

Trait Implementations

impl Clone for ChannelVoiceMsg

fn clone(&self) -> ChannelVoiceMsg

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChannelVoiceMsg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ChannelVoiceMsg

fn eq(&self, other: &ChannelVoiceMsg) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
