Sample Editor

The Sample Editor opens a large interactive waveform on top of the timeline so the audio fills the screen while every editor control sits in a single bar at the bottom. It is the only place where transient markers, slice settings, and the source-level BPM grid are edited.

​

Opening the Editor

The sheet locks input to the timeline behind it. Press Done (or Return) to close. The window can be resized from its minimum (1280 × 540) upward to any size your display allows.

​

Layout

The waveform fills the body of the sheet. A single bar at the bottom holds the controls for the currently selected mode. Both the waveform and the controls are tinted with the colour of the track that owns the sample. A segment picker on the left of the bar switches between three modes: Press ⌘1 to switch to Slices and ⌘2 to switch to Tempo from the keyboard.

​

Waveform Interactions

The waveform reacts to the same gestures in both modes — only the click target differs. The right hand never leaves the arrow cluster: step from marker to marker with the bare arrows, hold ⌘ to shove the selected marker, add ⌥ for sample-accurate alignment. Letter keys play the slices of the sample for audition (same layout as Musical Typing for audio slices).

​

Slices Mode

​

Transient Source

A picker selects how transient markers are produced:

​

Editing Markers (Slices Mode)

The selected slice is the one whose start marker the ⌘-arrow nudge moves. Selection is set with the bare ← / → arrows, by clicking a marker, or by playing a slice with its letter key.

​

Sample Operations (Slices Mode)

A chip in the top-right corner of the waveform offers two non-destructive operations on the source sample. Both write back into the sample’s parameters — the original audio file is not modified, and pressing the same button again removes the effect.

​

Slice Playback Controls

These mirror the same controls on the Inspector.

​

Tempo Mode

Tempo mode shows a beat grid overlaid on the waveform. The grid is derived from the source’s effective BPM and uses the bar/beat lines to give the user a visual reference for aligning the audio.

​

Source BPM and Stretch Settings

The toolbar exposes the same source-level fields as the Inspector, packed into a single row: See Time Stretching for the full description of each mode.

​

Aligning the Beat Grid

When the first downbeat of the audio doesn’t sit at the start of the file, the grid can be moved without changing the BPM: The current offset is shown in seconds in the chip. The offset is persisted on the source and re-applied the next time the editor is opened.

​

Stems Mode

Stems mode replaces the single waveform with a stack of stem lanes — one row per stem (vocals, drums, bass, other for Song Stems; kick, snare, cymbals, toms for Drum Elements). Each lane has its own volume, mute, and solo controls so you can rebalance the parts inside one sample without splitting the clip across multiple tracks. Three states the user can land in: The toolbar picker on the right of the bar selects the algorithm (Song Stems / Drum Elements). A compact Re-generate action sits beside it. While a bake runs, the body of the editor swaps to a progress view; once the bundle lands on the source, the lanes appear automatically. This is an in-place alternative to splitting a clip into separate stem tracks — both flows use the same models, but stems mode keeps everything on one track and one sample. Use stems mode when you want to mix the layers as a single instrument; use the track-split flow when you want to arrange them independently.

Shortcuts

These keys are specific to the Sample Editor sheet. The slice-audition letter keys follow the Musical Typing layout.
