Struct TimeGrid 

pub struct TimeGrid {
    pub tpq: u32,
    pub step: Time,
}

Timing grid for a piano roll.

Couples a ticks-per-quarter resolution with a quantization step measured in whole-note fractions.

Examples

use sim_lib_music_core::TimeGrid;

let grid = TimeGrid::default();
assert_eq!(grid.tpq, 480);

Fields

tpq: u32

Ticks per quarter note.

step: Time

Quantization step, as a fraction of a whole note.

Implementations

impl TimeGrid

pub fn new(tpq: u32, step: Time) -> Result<Self, MusicError>

Builds a grid, rejecting a zero tpq or a non-positive step.

Returns MusicError::InvalidPianoRollGrid when the inputs are invalid.
