pub struct ControlChange {
    pub channel: MidiChannel,
    pub controller: u8,
    pub value: f32,
}

Control Change (CC) message.

Fields

Implementations

impl ControlChange

pub const fn is_mod_wheel(&self) -> bool

Check if this is a modulation wheel CC (CC1).

pub const fn is_sustain_pedal(&self) -> bool

Check if this is a sustain pedal CC (CC64).

pub const fn is_expression(&self) -> bool

Check if this is an expression pedal CC (CC11).

pub const fn is_volume(&self) -> bool

Check if this is a volume CC (CC7).

pub fn is_sustain_on(&self) -> bool

Check if sustain is pressed (value >= 0.5).

pub const fn is_bank_select_msb(&self) -> bool

Check if this is a Bank Select MSB (CC0).

pub const fn is_bank_select_lsb(&self) -> bool

Check if this is a Bank Select LSB (CC32).

pub const fn is_bank_select(&self) -> bool

Check if this is any Bank Select message (CC0 or CC32).

pub const fn is_14bit_msb(&self) -> bool

Check if this controller is an MSB (CC 0-31) that has a corresponding LSB.

MIDI defines CC 0-31 as MSB controllers with CC 32-63 as their LSB pairs.

pub const fn is_14bit_lsb(&self) -> bool

Check if this controller is an LSB (CC 32-63) that pairs with an MSB.

MIDI defines CC 32-63 as LSB controllers that pair with CC 0-31.

pub const fn lsb_pair(&self) -> Option<u8>

Returns the LSB controller number for this MSB (CC 0-31 → CC 32-63).

Returns None if this isn’t an MSB controller.

pub const fn msb_pair(&self) -> Option<u8>

Returns the MSB controller number for this LSB (CC 32-63 → CC 0-31).

Returns None if this isn’t an LSB controller.

pub const fn is_rpn_msb(&self) -> bool

Check if this is an RPN MSB (CC 101).

pub const fn is_rpn_lsb(&self) -> bool

Check if this is an RPN LSB (CC 100).

pub const fn is_rpn_select(&self) -> bool

Check if this is any RPN selection message (CC 100 or 101).

pub const fn is_nrpn_msb(&self) -> bool

Check if this is an NRPN MSB (CC 99).

pub const fn is_nrpn_lsb(&self) -> bool

Check if this is an NRPN LSB (CC 98).

pub const fn is_nrpn_select(&self) -> bool

Check if this is any NRPN selection message (CC 98 or 99).

pub const fn is_data_entry_msb(&self) -> bool

Check if this is a Data Entry MSB (CC 6).

pub const fn is_data_entry_lsb(&self) -> bool

Check if this is a Data Entry LSB (CC 38).

pub const fn is_data_entry(&self) -> bool

Check if this is any Data Entry message (CC 6 or 38).

pub const fn is_data_increment(&self) -> bool

Check if this is a Data Increment (CC 96).

pub const fn is_data_decrement(&self) -> bool

Check if this is a Data Decrement (CC 97).

pub const fn is_rpn_nrpn_related(&self) -> bool

Check if this CC is part of an RPN/NRPN sequence.

Returns true for CC 6, 38, 96-101.

Trait Implementations

impl Clone for ControlChange

fn clone(&self) -> ControlChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlChange

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

Formats the value using the given formatter.

impl PartialEq for ControlChange

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

Tests for self and other values to be equal, and is used by ==.

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

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