keyid

Uses the Camelot system to either:

• suggest the next track (based on your current Master deck)
  • Rekordbox takes 60 seconds (by default) to add the Master deck track to your history. See here for how to change this setting
• generate a new playlist from the given playlist name (or your whole collection) with the selections in a compatible key and tempo.

This assumes you have analyzed your collection using the Alphanumeric key notation.

Why

• Q: Rekordbox already has a "Traffic Light" system that can suggest tracks to play that are in key, why do this?
• A: It sucks, and this program has a better set of rules that finds stuff that works more harmonically.

Prerequisites

• Install rekordbox
• Set the key display format to Alphanumeric
• Analyze your tracks. I recommend using Mixed In Key (other key detection software makes this program mostly useless because they're almost always wrong)

Usage

Usage of ./keyid:
  -debug
        Enable debug logging
  -mode string
        One of 'suggest' or 'generate' (default "suggest")
  -playlist string
        Name of Rekordbox Playlist to use (uses whole collection by default)
  -random
        Randomize playlist before 'generate'
  -startWith string
        Some part of the Track Title to start with in 'generate' mode (otherwise
        starts with first track in provided 'playlist')

Examples

• To suggest the next track based on what you're currently playing (lists all compatible tracks from your collection):

./keyid

• To use an existing playlist for the pool of tracks to find:

./keyid -playlist 'My Cool Playlist 2024'

• You can also suggest based on the name of a track you want, instead of the one that's playing

./keyid -playlist 'My Cool Playlist 2024' -startWith 'Cafe Del Mar

• To generate a new playlist based on your whole collection (also accepts -playlist):

./keyid -mode generate -playlist 'My Cool Playlist 2024' -startWith 'Cafe Del Mar'

• NOTE: You can provide a track to start with from your source playlist when in generate mode.
• NOTE: Generate mode can randomize the order of the tracks it looks at in the provided playlist, so you can run it multiple times to get a new selection if it doesn't generate something useful (see -random flag)
• NOTE: Track printout has 4 columns, BPM, Key, Energy, and Artist+Title, for example:
  • 122 10A 6 Serious Dancers - In The Beginning (Hernan Cattaneo & Simply City Remix)

Do you really use this?

• Yes, I do. I used to do this manually in my head.

Roadmap

• Generate .m3u playlists in generate mode
• Multiplatform downloadable builds
• Support for other DJ Software (Serato, Virtual DJ, Engine DJ, Mixxx, etc)
• Better documentation
