Affected event.

before: Time

Exact prior onset.

after: Time

Exact new onset.

Duration

A note duration changed.

Fields

event_id: ObjectId

Affected event.

before: Time

Exact prior duration.

after: Time

Exact new duration.

Articulation

A note articulation changed.

Fields

event_id: ObjectId

Affected event.

before: Articulation

Prior articulation.

after: Articulation

New articulation.

Pitch

A note pitch changed while its pitch class stayed fixed.

Fields

event_id: ObjectId

Affected event.

before: Pitch

Prior pitch.

after: Pitch

New pitch.

Voice

A note moved to another voice.

Fields

event_id: ObjectId

Affected event.

before: ObjectId

Prior voice identity.

after: ObjectId

New voice identity.

CreatedVoice

Voice separation allocated a new voice identity.

Fields

voice_id: ObjectId

New identity.

source_voice_id: ObjectId

Original voice from which it was split.

RepeatedIdentity

Repetition derived fresh note/event identities for a later occurrence.

Fields

source_note_id: ObjectId

Original logical note identity.

source_event_id: ObjectId

Original event identity.

repeated_note_id: ObjectId

Derived logical note identity.

repeated_event_id: ObjectId

Derived event identity.

occurrence: usize

Zero-based occurrence index, always greater than zero.

Removed

A rhythm mask or slice removed an event.

Fields

note_id: ObjectId

Removed logical note identity.

event_id: ObjectId

Removed event identity.

reason: &'static str

Stable reason for removal.

AddedVoice

An additive transform introduced a new independent voice.

Fields

voice_id: ObjectId

New voice identity.

AddedNote

An additive transform introduced a note without changing source notes.

Fields

voice_id: ObjectId

Containing voice.

note_id: ObjectId

New logical note identity.

event_id: ObjectId

New event identity.

RemovedVoice

Reversing an additive transform removed its introduced voice.

Fields

voice_id: ObjectId

Removed voice identity.
