Expand description

A single undoable action.

Variants§

DeleteNotes

Notes were deleted from a clip (undo = add them back).

Fields

§track_idx: usize

§clip_idx: usize

§notes: Vec<NoteSnapshot>

PasteNotes

Notes were added to a clip via paste (undo = remove them).

Fields

§track_idx: usize

§clip_idx: usize

§notes: Vec<NoteSnapshot>

DrawNote

A note was drawn (added).

Fields

§track_idx: usize

§clip_idx: usize

§note: NoteSnapshot

RemoveNote

A note was toggled off (removed by pressing n on it).

Fields

§track_idx: usize

§clip_idx: usize

§note: NoteSnapshot

DeleteClip

A clip was deleted.

Fields

§track_idx: usize

§clip_idx: usize

§clip: Clip

MoveNotes

Notes were moved in the piano roll. Stores snapshots of the notes BEFORE the move so undo can restore their original positions.

Fields

§track_idx: usize

§clip_idx: usize

§before: Vec<(usize, NoteSnapshot)>

(note_index, original_snapshot) for each moved note.

ModifyClip

A clip’s position or size was changed (move/stretch/trim). Stores the clip’s previous start_tick, length_ticks, notes, and hidden_notes.

Fields

§track_idx: usize

§clip_idx: usize

§prev_start: i64

§prev_length: i64

§prev_notes: Vec<NoteSnapshot>

§prev_hidden: Vec<(i64, i64, u8, u8)>

AddClip

A clip was added (paste/duplicate). Undo = remove it.

Fields

§track_idx: usize

§clip_idx: usize

DeleteTrack

A track was deleted. Stores full track state for restoration.

Fields

§track_idx: usize

§track: TrackState

§mixer_id: usize
