Struct TransportState 

Source 
pub struct TransportState {
    pub is_playing: bool,
    pub bpm: f64,
    pub frame_pos: u64,
    pub time_sig_num: u8,
    pub time_sig_den: u8,
    pub bar_start_frame: u64,
}
Expand description

Musical transport state — derived from JACK/PipeWire transport or MIDI clock.

Carries the current bar/beat/tempo state of the host timeline. Populated by the I/O backend once per processing block.

Fields§

§is_playing: bool

Whether the host transport is currently rolling (playing).

§bpm: f64

Current tempo in beats per minute.

§frame_pos: u64

Absolute transport frame (song position in samples).

§time_sig_num: u8

Beats per bar — time signature numerator (default 4).

§time_sig_den: u8

Beat unit — time signature denominator (default 4 = quarter note).

§bar_start_frame: u64

Sample position where the current bar started.
