Member Data Documentation

block_index

std::uint64_t pulp::playback::TransportSnapshot::block_index = 0

frame_count

std::uint32_t pulp::playback::TransportSnapshot::frame_count = 0

has_precise_host_loop

bool pulp::playback::TransportSnapshot::has_precise_host_loop = false

host_loop_end_beats

double pulp::playback::TransportSnapshot::host_loop_end_beats = 0.0

host_loop_start_beats

double pulp::playback::TransportSnapshot::host_loop_start_beats = 0.0

is_playing

bool pulp::playback::TransportSnapshot::is_playing = false

loop

LoopRegion pulp::playback::TransportSnapshot::loop {}

meter

MeterSignature pulp::playback::TransportSnapshot::meter {}

playback_epoch

std::uint64_t pulp::playback::TransportSnapshot::playback_epoch = 0

Epoch of ranges[0].

Later ranges carry their own epoch so a scrub-anchor discontinuity may be represented precisely when it splits a block.

range_count

std::uint8_t pulp::playback::TransportSnapshot::range_count = 0

ranges

std::array<TransportRange, 2> pulp::playback::TransportSnapshot::ranges {}

reset_requested

bool pulp::playback::TransportSnapshot::reset_requested = false

sample_rate

timebase::RationalRate pulp::playback::TransportSnapshot::sample_rate {}

scrubbing

bool pulp::playback::TransportSnapshot::scrubbing = false

True while the transport is rendering scrub windows.

is_playing is also true in that case: audio advances even when the musical transport is stopped, and consumers that only care whether the playhead moves need no scrub-specific branch.

tempo_bpm

double pulp::playback::TransportSnapshot::tempo_bpm = 120.0

Convenience mirror of ranges[0].tempo_bpm for block-level consumers.

tempo_map

const timebase::CompiledTempoMap* pulp::playback::TransportSnapshot::tempo_map = nullptr

Non-owning identity of the exact compiled map used to resolve ranges.

The map must outlive consumers of this callback snapshot.

time_sig_changed

bool pulp::playback::TransportSnapshot::time_sig_changed = false

transport_changed

bool pulp::playback::TransportSnapshot::transport_changed = false

transport_started

bool pulp::playback::TransportSnapshot::transport_started = false
