pyrekordbox 0.0.4

Inofficial Python package for interacting with the library, analysis and export data of Pioneer's Rekordbox DJ software.

pyrekordbox

pyrekordbox is a Python package for interacting with the library and export data of Pioneer's Rekordbox DJ Software. It currently supports

• Rekordbox XML database
• Analysis files (ANLZ)
• My-settings files
• Rekordbox 6 master.db database

Note: This project is not affiliated with Pioneer Corp. or its related companies in any way and has been written independently!

⚠️	This project is still under heavy development and might contain bugs or have breaking API changes in the future.

Installation

pyrekordbox is available on PyPI:

pip install pyrekordbox

Alternatively, it can be installed via GitHub

pip install git+https://github.com/dylanljones/pyrekordbox.git@VERSION

where VERSION is a release, tag or branch name. The project can also be cloned/forked and installed via

python setup.py install

Some features need additional dependencies (see the Rekordbox 6 database section).

Usage

Read the documentation on ReadTheDocs!

Configuration

pyrekordbox looks for installed Rekordbox versions and sets up the configuration automatically. The configuration can be checked by calling:

from pyrekordbox import show_config

show_config()

which, for example, will print

Pioneer:
   app_dir =      C:\Users\user\AppData\Roaming\Pioneer
   install_dir =  C:\Program Files\Pioneer
Rekordbox 5:
   app_dir =      C:\Users\user\AppData\Roaming\Pioneer\rekordbox
   db_dir =       C:\Users\user\AppData\Roaming\Pioneer\rekordbox
   db_path =      C:\Users\user\AppData\Roaming\Pioneer\rekordbox\datafile.edb
   install_dir =  C:\Program Files\Pioneer\rekordbox 5.8.6
   version =      5.8.6

If for some reason the configuration fails the values can be updated by providing the paths to the directory where Pioneer applications are installed (pioneer_install_dir) and to the directory where Pioneer stores the application data (pioneer_app_dir)

from pyrekordbox.config import update_config

update_config(pioneer_install_dir, pioneer_app_dir)

Alternatively the two paths can be specified in a configuration file under the section rekordbox. Supported configuration files are pyproject.toml, setup.cfg, rekordbox.toml, rekordbox.cfg and rekordbox.yml.

Rekordbox XML

The Rekordbox XML database is used for importing (and exporting) Rekordbox collections including track metadata and playlists. They can also be used to share playlists between two databases. Exporting XML databases was removed in Rekordbox 6. Update: In newer Rekordbox 6 versions the XML export feature returned!

pyrekordbox can read and write Rekordbox XML databases.

from pyrekordbox.xml import RekordboxXml

xml = RekordboxXml("database.xml")

track = xml.get_track(0)    # Get track by index (or TrackID)
track_id = track.TrackID    # Access via attribute
name = track["Name"]        # or dictionary syntax

path = "/path/to/file.mp3"
track = xml.add_track(path) # Add new track
track["Name"] = "Title"     # Add attributes to new track
track["TrackID"] = 10       # Types are handled automatically

# Get playlist (folder) by path
pl = xml.get_playlist("Folder", "Sub Playlist")
keys = pl.get_tracks()  # Get keys of tracks in playlist
ktype = pl.key_type     # Key can either be TrackID or Location

# Add tracks and sub-playlists (folders)
pl.add_track(track.TrackID)
pl.add_playlist("Sub Sub Playlist")

Rekordbox ANLZ files

Rekordbox stores analysis information of the tracks in the collection in specific files, which also get exported to decives used by Pioneer professional DJ equipment. The files have names like ANLZ0000 and come with the extensions .DAT, .EXT or .2EX. They include waveforms, beat grids (information about the precise time at which each beat occurs), time indices to allow efficient seeking to specific positions inside variable bit-rate audio streams, and lists of memory cues and loop points.

pyrekordbox can parse all three analysis files, although not all the information of the tracks can be extracted yet.

from pyrekordbox.anlz import AnlzFile

anlz = AnlzFile.parse_file("ANLZ0000.DAT")
beat_grid = anlz.getone("beat_grid")

Changing and creating the Rekordbox analysis files is planned as well, but for that the full structure of the analysis files has to be understood.

Rekordbox MySettings

Rekordbox stores the user settings in *SETTING.DAT files, which get exported to USB devices. These files are either in the PIONEERdirectory of a USB drive (device exports), but are also present for on local installations of Rekordbox 6. The setting files store the settings found on the "DJ System" > "My Settings" page of the Rekordbox preferences. These include language, LCD brightness, tempo fader range, crossfader curve and other settings for Pioneer professional DJ equipment.

pyrekordbox supports both parsing and writing MySetting files.

from pyrekordbox.mysettings import read_mysetting_file

mysett = read_mysetting_file("MYSETTINGS.DAT")
sync = mysett.get("sync")
quant = mysett.get("quantize")

Rekordbox 6 database

Rekordbox 6 now uses a SQLite database for storing the collection content. The old DeviceSQL of Rekordbox 5 was probably too old for Pioneer to keep using adequately, especially with the Rekordbox Agent. Unfortunatly, the new master.db SQLite database is encrypted using SQLCipher, which means it can't be used without the encryption key. Pioneer did this because they prefer that no one outside of Pioneer touches it. However, since your data is stored and used locally, the key must be present on the machine running Rekordbox.

pyrekordbox can unlock the new Rekordbox master.db SQLite database and provides an easy interface for accessing the data stored in it:

from pyrekordbox import Rekordbox6Database

db = Rekordbox6Database()
for item in db.get_content():
    print(item.Title, item.Artist.Name)

Changing entries of the database is not supported yet since it is not guaranteed that the database could be corrupted from writing to it. However, this feature will by added after some testing.

Dependencies

Unlocking the new Rekordbox 6 master.db database file requires SQLCipher.

So far I did not find a reliable dependency for using SQLCipher with Python on Windows. For now, SQLCipher can be used with the included DLL's by replacing the Python SQLite DLL's (see this StackOverflow discussion):

1. rename sqlcipher.dll to sqlite3.dll and replace the existing file in the Python DLLs folder with it
2. copy libcrypto-1_1.dll into the Python DLLs folder (optional, should work without)
3. copy libssl-1_1.dll into the Python DLLs folder (optional, should work without)

After that SQLCipher-databases can be unlocked via the normal sqlite3 package by providing the key via the PRAGMA key='db-key' SQL statement.

❗	The included DLL's only work with Python 3.8! For other platforms and Python versions (specificly the version of the included SQLite3 libary) the DLL's have to be built from source.

File formats

A summary of the Rekordbox file formats can be found in the documentation:

• Rekordbox XML format
• ANLZ file format
• MySetting file format
• Rekordbox 6 database

If you encounter an issue or want to contribute to pyrekordbox, please feel free to get in touch, open an issue or open a pull request!

pyrekordbox is tested on Windows and MacOS, however some features can't be tested in the CI setup since it requires a working Rekordbox installation. The auto-configuration (discovering Rekordbox file locations) is tested on Windows, but help would be appreciated on MacOS.
