This page lists the main local paths used by Meiji Sampler.

​
macOS paths

​
App state and config

  • session state: ~/Library/Application Support/Meiji Sampler/state.json
  • settings: ~/Library/Application Support/Meiji Sampler/config.json
  • auth state: ~/Library/Application Support/Meiji Sampler/auth.json
  • analytics anonymous id: ~/Library/Application Support/Meiji Sampler/anonymous_id

​
Projects

  • projects directory: ~/Documents/Meiji Sampler/Projects/
  • project extension: .meiji

​
Bounces

  • bounce output directory: ~/Documents/Meiji Sampler/Bounces/
  • DJ master recordings: DJ Set YYYY-MM-DD HH-MM-SS.wav in the same directory, with collision suffixes and numbered Part 2 rollover files when needed
  • interrupted DJ master recordings: retained .partial files in the same directory. These are recovery artifacts, not completed bounces.

​
Recordings

  • recordings directory: ~/Music/Meiji Sampler/recordings/
  • Splice licensed downloads: ~/Music/Meiji Sampler/splice/

​
Packs

  • packs directory: ~/Library/Application Support/Meiji Sampler/Packs/

​
Cache

  • cache directory: ~/Library/Caches/Meiji Sampler/

​
Linux paths

​
App state and config

  • config directory: $XDG_CONFIG_HOME/meiji-sampler/ (default ~/.config/meiji-sampler/)

​
Data

  • data directory: $XDG_DATA_HOME/meiji-sampler/ (default ~/.local/share/meiji-sampler/)

​
Cache

  • cache directory: $XDG_CACHE_HOME/meiji-sampler/ (default ~/.cache/meiji-sampler/)

​
Recordings

  • recordings directory: ~/Meiji Sampler/recordings/ when no audio directory is available
  • Splice licensed downloads: ~/Meiji Sampler/splice/ when no audio directory is available

​
Packs

  • packs directory: $XDG_DATA_HOME/meiji-sampler/Packs/ (default ~/.local/share/meiji-sampler/Packs/)
Project, bounce, and recording paths may resolve into your standard user document and audio directories when available. DJ master recordings use the Bounces directory on every platform. They are stereo IEEE Float32 32-bit WAV files at the active output rate. Both output modes capture the safety-limited post-PerformFX software master. REV7 hardware mode captures the unity-gain sum of both processed deck stems before the physical mixer, excluding physical EQ, faders, crossfader, microphone or auxiliary input, and master processing. See File Formats for the source and format, and File And Project Problems before recovering a .partial file.

​
Windows paths

​
App state and config

  • config directory: %APPDATA%\Meiji Sampler\

​
Data

  • data directory: %LOCALAPPDATA%\Meiji Sampler\ (includes the cache\ subfolder)

​
Recordings

  • recordings directory: %USERPROFILE%\Music\Meiji Sampler\recordings\
  • Splice licensed downloads: %USERPROFILE%\Music\Meiji Sampler\splice\

​
Packs

  • packs directory: %LOCALAPPDATA%\Meiji Sampler\Packs\

​
Project structure

A .meiji project stores:
  • format version
  • project name
  • created and saved timestamps
  • app version
  • flattened session state
The session state can include:
  • pad assignments
  • mixer values
  • loops
  • scenes
  • overrides for trim, chop, loop mode, and sample-type metadata

​
Recovery behavior

Persistence writes use backup files and recovery helpers where possible. If a primary file is corrupt, the app may attempt to restore from a .bak sibling.

​
Uninstalling

To fully remove Meiji Sampler, delete the application and then remove the directories listed above for your platform.
  • On macOS, delete ~/Library/Application Support/Meiji Sampler/ and ~/Library/Caches/Meiji Sampler/.
  • On Linux, delete the config, data, and cache directories.
  • On Windows, delete the %APPDATA%\Meiji Sampler\ and %LOCALAPPDATA%\Meiji Sampler\ directories.
Packs are stored inside the data directory — deleting it removes them automatically. On macOS and Linux the cache is a separate directory. On Windows the cache folder is nested inside the data directory, so deleting the data path removes both. To free up disk space while keeping your config, delete only the Packs subfolder from the data directory.
