Struct Macro 

pub struct Macro {
    pub values: Vec<i16>,
    pub step: MacroStep,
    pub loop_start: Option<usize>,
}

An integer instrument sequence. Index zero applies to the first sample. At its end it holds, or loops to loop_start after playing the initial prefix once. Volume values are 0..=15; duty values 0..=3 select 12.5/25/50/75 percent; arpeggio values are -48..=48 semitones; fine pitch is -1200..=1200 cents.

Fields

values: Vec<i16>

step: MacroStep

loop_start: Option<usize>

Implementations

impl Macro

pub fn new(values: Vec<i16>, step: MacroStep) -> Result<Self>

pub fn validate(&self) -> Result<()>

pub fn value_at( &self, frame: u64, sample_rate: u32, tempo: u16, ticks_per_quarter: u16, ) -> Result<i16>

Query a validated macro at a relative note age. Steps use a rational clock (no cumulative rounding). Tick boundaries can differ by one sample from globally floor-rounded score note positions.

Trait Implementations

impl Clone for Macro

fn clone(&self) -> Macro

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Macro

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

Formats the value using the given formatter.

impl Eq for Macro

impl Hash for Macro

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Macro

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

Equality operator ==.

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

Inequality operator !=.
