Browse and import samples
Open Samples from the Project page. The browser has two places:
- Samples shows sounds already copied into the current project.
- Import shows sounds available to add.
Add a sample to the project
- On Project, move to Samples and choose Browse.
- Choose Import in the bottom bar.
- Move through folders with Up and Down; press Enter to open one.
- Select a WAV and hold Play to preview it.
- Choose Import and press Enter.
The browser stays open so you can add more sounds. Hold Shift and tap Option to switch between Samples and Import at any time.

The title identifies the browser source; actions stay in the bottom bar.
Browser controls
| Input | Result |
|---|---|
| Up / Down | Select the previous or next entry. |
| Option + Up / Down | Jump eight entries. |
| Left / Right | Select an action in the bottom bar. |
| Enter | Open a directory or run the selected action. |
| Hold Play | Preview the selected WAV; release Play to stop. |
| Shift + Play | Import the selected library WAV immediately. |
| Option + Left | Go to the parent library directory without leaving the browser. |
| Shift + Left | Leave the browser and return to its owner page. |
Stop normal playback before previewing a WAV. The footer shows the selected file's size and preview volume.
Project pool actions
For a project sample, the bottom bar offers:
- Edit opens the Sample Editor.
- Import switches to the
/sampleslibrary. - Delete removes an unused sample after confirmation.
Option + Enter is a delete shortcut when a project file is selected. A file marked * is referenced by at least one Sample instrument and cannot be deleted. Deletion is also blocked while transport or sample preview is active.
Library actions
Directories have an Open action and are shown with a / prefix. Files have:
- Import, which copies and converts the WAV into the current project.
- Edit, which opens an editable copy before import.
- Back, which returns to the project pool.
Import fails instead of overwriting an existing project sample with the same resolved name. If the current instrument is a Sample instrument, a successful import assigns the new project sample to it and clears its slices.
The library stays open after a successful import, so several WAV files can be added in one visit. Each successful import becomes the current Sample instrument's selected file when the browser was opened from that instrument.
A ~ prefix marks a likely single-cycle WAV. Holding Play loops these previews.
Supported WAV input
Use an uncompressed mono or stereo WAV. Common PCM and floating-point WAV files are supported.
The Device page's Resampler setting changes accepted rates and project conversion:
| Resampler | Accepted source rate | Project copy |
|---|---|---|
NONE | 7,350–44,100 Hz | 16-bit PCM at the source rate |
LINEAR | 7,350–264,600 Hz | 16-bit PCM at 44,100 Hz |
If a WAV is too large or uses an unsupported format, NullPerator rejects it and keeps the project unchanged. See Files and compatibility for the complete format list.
