LibreCDJ

An experimental playground to develop a 4 Deck DJ Software for Linux.

Current screen design for future gui version:

Goals

• 4 Decks
• Good beat jumping/looping
• Good performance
• Low latency
• As best as possible playback/resampling
• Minimal & clean user interface
• Good library management
• Completely usable with Keyboard

Non-Goals

• No mixing/eq/effects. Use an external mixer or something like equis
• Session management. Use qpwgraph for this
• Radio Broadcasting
• Stem seperation (I'm up to support stem files though)
• Rekordbox/Serato export/import
  • If there's a good crate, maybe though

Supported Hardware

• Denon SC2000

How to run

Make sure you have pipewire/jack installed and a rust compiler. Also i recommend using kitty as a terminal (or any terminal supporting key release events).

- git clone the repo
- PIPEWIRE_QUANTUM=256 PLAYLISTS=/path/to/playlists LIBRARY=/path/to/your/music cargo run --release

Keybindings

• Arrow Keys => navigate library/file browser
• Enter => Load track to current Deck
• F1-F4 => Switch between Deck 1-4
• q => Cue
• w => Play
• a,s,d,f => Nuding
• y,x,c,v => Adjusting Pitch
• i,o,p,ü,+ => Set loop starting at current playhead
• I,O,P,Ü,* => Set loop endingt at current playhead
• n,m,,,.,- => Jump x beats forward
• N,M,;,:,_ => Jump x beats backwards
• Space => Switch waveform zoom
• F10 => Debug logs
• End => Exit program
