Detailed Description

Streams one mixer control's value in timeline-sample order without allocating.

Positions must be non-decreasing between seeks; a seek is the explicit discontinuity, which is the same contract the device-delivery cursor works under. Evaluation goes through the shared segment evaluator, so an automated fader and an automated plugin parameter read one curve the same way.

Member Function Documentation

automated()

bool pulp::playback::TrackMixerControlCursor::automated ( ) const

inlinenoexcept

Whether any position can yield something other than the constant.

reset()

void pulp::playback::TrackMixerControlCursor::reset ( const AutomationProgram * program, float constant )

inlinenoexcept

restart()

void pulp::playback::TrackMixerControlCursor::restart ( const timebase::CompiledTempoMap & map )

inlinenoexcept

Begins a fresh monotonic run.

Callers that revisit earlier positions — a second channel over the same span, a loop wrap — restart rather than stepping backwards, which the forward cursor cannot express.

value_at()

float pulp::playback::TrackMixerControlCursor::value_at ( timebase::SamplePosition sample )

inlinenoexcept

value_at_tick()

float pulp::playback::TrackMixerControlCursor::value_at_tick ( long double tick )

inlinenoexcept

Evaluates a host-projected fractional document tick without first quantizing it through the integer sample domain.
