Detailed Description

The compiled form of a track's own level and stereo placement.

A null lane pointer means the authored constant governs for the whole timeline; a non-null one supersedes it entirely, so a lane and a constant never both apply and the result never depends on which was read first. The pointers borrow from the TrackAutomationProgram the owning TrackProgram holds alive.

transparent()

bool pulp::playback::TrackMixerProgram::transparent ( ) const

inlinenoexcept

Whether this mixer can be skipped entirely.

A track that was never touched renders through exactly the code path it did before mixer state existed, which is what keeps existing golden renders bit-identical.
