PadReady v2.2.0

Get any sound in your library ready for your hardware sampler in one drag. PadReady batch-converts audio to the exact format your sampler wants (Sonicware Lofi-12 XT, Elektron Digitakt, Roland SP-404, Polyend Tracker, Teenage Engineering OP-1 and more) and packs the result as a zip kit you can share. Powered by the SoX (Sound eXchange) engine.

PadReady was previously called the Sonicware Lofi-12 XT Tool.

Version 2.0 is a complete rewrite in Electron (Node.js) with a new layout: all hardware settings and the output folder are in the sidebar, and the main window has the file list, a waveform preview and a convert bar with a progress bar. The window can be resized, and the grey and orange colors are the same as before.

The app now runs on Tauri instead of Electron: it uses the WebView2 that is built into Windows 10 and 11, so the download is about a tenth of the size and the app starts faster and uses less memory. Everything looks and works the same, and your settings carry over.

🚀 Features

• Batch processing: Drag and drop multiple files or entire folders (WAV, AIFF, MP3, FLAC, OGG; WMA and M4A need ffmpeg).

• Hardware profiles: One-click presets for:

  Device	Sample rate	Bit depth	Channels	Format
  Sonicware Lofi-12 XT	24 kHz	16-bit	Mono	WAV
  Sonicware Lofi-12 (Original)	12 kHz	16-bit	Mono	WAV
  Elektron Digitakt (Mk1)	48 kHz	16-bit	Mono	WAV
  Elektron Digitakt II	48 kHz	16-bit	Stereo	WAV
  Roland SP-404MKII	48 kHz	16-bit	Stereo	WAV
  Roland SP-404SX / SP-404A	44.1 kHz	16-bit	Stereo	WAV
  Polyend Tracker	44.1 kHz	16-bit	Mono	WAV
  Teenage Engineering OP-1 / OP-1 field	44.1 kHz	16-bit	Mono	AIFF
  Teenage Engineering OP-Z	44.1 kHz	16-bit	Mono	AIFF

  You can also pick sample rate (12/24/44.1/48 kHz), bit depth (16/24-bit), channels (mono/stereo) and format (WAV/AIFF) by hand.

  Missing your sampler? Add it — it's one line.

• Smart filenames: Replaces spaces and invalid characters with underscores and never overwrites existing files (a numbered suffix is added instead).

• Normalize: Peak normalization to 0 dB for consistent volume across all your samples.

• Auto-Trim: Removes silence at the start and end of each sample.

• Reverse: Reverses samples during conversion (output files get a _rev suffix).

• Export as Zip: Packs the files from the last conversion into one zip file, ready to share as a kit. The zip includes a README.txt with the device and settings the kit was made for.

• Preview: Click a file to play it and see its waveform (WAV, MP3, FLAC, OGG and M4A; WMA can be converted but not previewed).

• Blazing fast: Uses the SoX engine and converts in the background, so the window stays responsive.

• Clear errors: Converted files get a ✓ and files that fail are highlighted in the list; hover over one to see the SoX error message.

• SoX status: The bottom of the sidebar shows whether SoX or SoX-NG was found; hover over it to see the path.

• Multilingual: English, Danish, German, Spanish, French, Italian and Swedish (switch with the language picker at the bottom of the sidebar).

• Open source: Free to use, modify, and distribute.

Output is WAV or AIFF.

🛠 Installation

1. Download the tool: Get the latest release from the Releases page:

   • PadReady_x.y.z_x64-setup.exe is a normal step-by-step installer: choose whether to install just for you (no admin rights needed) or for all users, and pick the install folder. It adds a Start menu and desktop shortcut, and can be removed again from Windows Settings > Apps. If WebView2 is missing (only on old Windows versions), the installer downloads it.
   • PadReady-x.y.z-portable.zip runs without installing: unzip it anywhere and start PadReady.exe (keep the sox folder next to it).

   If you have PadReady 2.x installed, uninstall it from Windows Settings > Apps first; your settings are kept.

2. SoX is included: PadReady comes with SoX-NG 14.7.2, the audio engine that does the conversion, so there is nothing else to install. It reads WAV, AIFF, MP3, FLAC and OGG.

   To use your own SoX instead (for example a build that also reads WMA and M4A through ffmpeg), place sox.exe or sox_ng.exe and its .dll files in the folder you installed PadReady to. The tool looks for SoX in this order:

   • the same folder as the tool (for the installed version that is the folder you picked, by default %LOCALAPPDATA%\PadReady for just you or C:\Program Files\PadReady for all users),
   • C:\Program Files (x86)\sox-14-4-2\,
   • any folder on your PATH,
   • the SoX-NG that comes with PadReady.

3. Run: Open the tool and you are ready to go.

Settings are stored in %APPDATA%\PadReady\settings.json. Converted files go to Documents\PadReady by default.

📖 How to Use

1. Add files: Drag and drop audio files or folders into the list, or use the Add Files / Add Folder buttons. Adding a folder doesn't include its subfolders.
2. Set output: Choose where you want your converted samples to be saved with Change Folder.
3. Adjust settings: Pick a target hardware profile, or select sample rate, bit depth and channels yourself. Enable Normalize, Auto-Trim or Reverse as needed.
4. Convert: Hit START CONVERSION. Progress is shown below the settings, along with the number of failed files, if any. Enable Open folder when done to have the output folder open automatically.
5. Share (optional): Click Export as Zip to save the converted files as one zip file you can share with other owners of the same sampler.

🧑‍💻 Building from Source

You need Node.js 20 or newer and Rust (see the Tauri prerequisites).

npm install

Run the app (it finds sox.exe / sox_ng.exe in the project folder, on your PATH, or in vendor/sox after npm run fetch-sox):

npm start

Run the tests (JavaScript with Node, then the Rust side with cargo test; the conversion tests are skipped if SoX isn't found):

npm test

Build the Windows installer. This first runs npm run fetch-sox, which downloads the official SoX-NG Windows build and its source code from Codeberg into vendor/ and checks their SHA-256 checksums, so SoX is bundled with the app:

npm run dist

Build the installer and the portable zip:

npm run dist:portable

The installer ends up in src-tauri/target/release/bundle/nsis/, the portable zip in dist/.

The app uses Tauri, so it can in principle run on macOS and Linux with sox installed from your package manager, but only Windows has been tested.

The original PureBasic version (v1.x) is still available in the git history and in the v1.0.0 release.

🎛 Adding Your Device

Device presets live in src/renderer/devices.json. To add a sampler, add one line and open a pull request:

{ "name": "Maker Model", "sampleRate": 44100, "bitDepth": 16, "channels": 1 }

• sampleRate: 12000, 24000, 44100 or 48000
• bitDepth: 16 or 24
• channels: 1 (mono) or 2 (stereo)
• format (optional): "wav" (default) or "aiff"

Please link the device's manual or spec page in the pull request so the values can be checked. npm test checks that every entry uses supported values. If your device needs a sample rate that isn't listed, add it to SAMPLE_RATES in src/renderer/renderer.js and to the test as well. Please also add a row to the table under Features.

If you can't make a pull request, open an issue with the device name and its sample format.

Third-party software

The installer and portable zip include SoX-NG 14.7.2 (sox_ng.exe), unchanged from the official Windows build. SoX-NG is licensed under the GNU General Public License v2; the license text is installed next to it as sox\COPYING. Its source code is attached to every PadReady release as sox_ng-14.7.2.tar.gz and is also available from the SoX-NG 14.7.2 release. The Windows build is statically linked with libraries such as libmad, libsndfile, FLAC, libvorbis and Opus; see the SoX-NG MXE build instructions for how it is built.
