Classes
struct	pulp::playback::TransportRange
struct	pulp::playback::TransportSnapshot
struct	pulp::playback::TransportPlayhead
	Where the transport is, published for a reader that is not the audio thread. More...
struct	pulp::playback::TransportLoopState
	The transport's accepted loop control state. More...
struct	pulp::playback::MasterTransportConfig
class	pulp::playback::MasterTransport
	Master musical transport with one control-thread writer and one audio-thread consumer. More...

Namespaces
namespace	pulp
namespace	pulp::playback

Typedefs
using	pulp::playback::MeterSignature = timebase::MeterSignature
using	pulp::playback::LoopRegion = timebase::LoopRegion
	The loop is a pair of document positions, so the timebase owns it and every rung that describes a loop names the same type.

Enumerations

Functions
TransportError	pulp::playback::detail::advance_playback_epoch (std::uint64_t &epoch) noexcept
	Advances an epoch without ever wrapping to an aliased identity.
bool	pulp::playback::valid_transport_ranges (const TransportSnapshot &transport) noexcept
	Validates the shared structural contract consumed by every block renderer.
long double	pulp::playback::host_mapped_document_sample_at_output_offset (const TransportRange &range, const timebase::CompiledTempoMap &tempo_map, std::uint32_t output_offset) noexcept
	Maps an output-frame boundary in a host-beat-mapped range back into the program's document-sample domain.
bool	pulp::playback::host_mapped_output_offset_for_tick (const TransportRange &range, timebase::TickPosition document_tick, std::uint32_t &output_offset) noexcept
	Maps an exact program event tick into a half-open host-beat-mapped transport range.
