Detailed Description

Durable statement of the tuning a project or one instrument plays in.

The reference pitch is exact millihertz rather than a float so a saved document states the pitch the user typed. A tuning is content-addressed rather than identity-addressed: the same scale referenced by two documents is the same bytes, and a copy or import carries the reference without any identity to remap.

keyboard_map_content

std::optional<ContentHash> pulp::timeline::TuningReference::keyboard_map_content

Sealed .kbm payload.

Only a Scala tuning may name one; absence means the scale maps onto the keyboard by its own default.

reference_pitch_millihertz

std::uint32_t pulp::timeline::TuningReference::reference_pitch_millihertz = kDefaultReferencePitchMillihertz

scale_content

std::optional<ContentHash> pulp::timeline::TuningReference::scale_content

Sealed .scl payload. Required when system is Scala, absent otherwise.

system

TuningSystem pulp::timeline::TuningReference::system = TuningSystem::EqualTemperament
