Struct MemoryTrackedMidiSource 

pub struct MemoryTrackedMidiSource { /* private fields */ }

An in-memory TrackedMidiSource backed by a time-sorted, track-tagged event vector.

Implementations

impl MemoryTrackedMidiSource

pub fn new(tpq: u32, events: Vec<TrackedMidiEvent>) -> Self

Creates a tracked source at tpq resolution, sorting events by tick and deriving the track count from the highest track index.
