Struct TimeSignature

pub struct TimeSignature {
    pub top: u8,
    pub bottom: u8,
    pub ticks_per_metronome_click: u8,
    pub number_32nd_in_quarter: u8,
}

A time signature

Examples

Assuming no_32nd_in_quarter is 8

• A time signature of 4/4, with a metronome click every 1/4 note, would be encoded FF 58 04 04 02 18 08. There are 24 MIDI Clocks per quarter-note, hence cc=24 (0x18).

• A time signature of 6/8, with a metronome click every 3rd 1/8 note, would be encoded FF 58 04 06 03 24 08 Remember, a 1/4 note is 24 MIDI Clocks, therefore a bar of 6/8 is 72 MIDI Clocks. Hence 3 1/8 notes is 36 (=0x24) MIDI Clocks.

Fields

top: u8

The number of beats per bar

bottom: u8

The size of those beats (1 = semibreve, 2 = minim, 3 = crotchet etc.)

ticks_per_metronome_click: u8

Clock ticks between metronome clicks

number_32nd_in_quarter: u8

The number of notated 32nd-notes in a MIDI quarter note - for a 1-1 corresponence this should be 8.

Trait Implementations

impl Clone for TimeSignature

fn clone(&self) -> TimeSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeSignature

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

Formats the value using the given formatter.

impl PartialEq for TimeSignature

fn eq(&self, other: &TimeSignature) -> 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.

impl Copy for TimeSignature
