OneLibraryCompanion 0.3.0

Changes since the published Mac/Raspberry Pi 0.2.3 preview.

Automatic discovery and local USB loading

  • Choose Automatic discovery in MENU to find CDJs on the local network. OLC reports the selected interface and searches again after network changes or disconnection. Manual IP connections and explicit interface selection remain available.
  • Local OneLibrary USB loading now works through automatic discovery for players 1 and 2. Leave player number 4 free for OLC; Mac serving still requires Local USB Support. One local library is served per connection session.
  • Overlapping load requests to the same player are rejected. OLC displays the local USB label for its served tracks.

Browser audio preview

  • Open PLAY in track details or hold a track title to open the browser player. Audio plays on the browser device, independently of the physical CDJs.
  • The popup includes play/pause, waveform seeking, artwork, time, BPM, key, genre, My Tags, comments and library color. Exported phrase sections and hot/memory cue markers appear when available.
  • Audio streams from host-attached or linked CDJ libraries, subject to browser format support. Local AIFF/AIFC files receive a temporary 44.1 kHz/16-bit WAV copy; original USB files and CDJ serving are unchanged.
  • Analysis previews now cover local and automatically discovered sources, combine DAT/EXT/2EX records, and retain valid cues and phrases when waveform data is missing.

Automatic set capture

  • Capture runs on the host without pressing Start set. More than 45 seconds of continuous playback or looping qualifies a track; browser preview is excluded.
  • More than five minutes without playback across the observed decks saves the session. Long tracks keep the session open; empty sessions are discarded.
  • Split set here separates performances, Finish set saves immediately, and Join previous set joins adjacent captured sessions while preserving edited track orders.
  • Start timestamps and repeat plays are retained. Short pauses, observation outages and restart recovery are handled without unnecessarily duplicating entries; uncertain observation boundaries are noted.

See the set history guide for qualification, recovery and editing details.

Headless Pi controls

  • MENU offers confirmed Restart OLC, Shut down host and Unmount USB controls on the packaged Linux user service.
  • Restart and shutdown block loaded OLC USB tracks unless fresh player status confirms they are stopped. Confirmation messages explain the emergency-loop and track-reload risk.
  • USB unmounting briefly stops OLC, handles mounted partitions together, reports completion and never forcibly unmounts a busy volume. Devices containing system mounts are excluded.
  • Shutdown and USB unmounting require the permissions described in the installation guide.

Connection reliability

  • Fixed a post-load disconnection caused by repeatedly copying cached waveform assets. Assets are cached once per track identity and serving packets drain without rebuilding the UI snapshot for every packet.
  • Failed USB analysis reads retry automatically, and the host records the last disconnection reason and timestamp for diagnostics.

Other performance and reliability improvements

  • Lossless packed waveform transfers reduced sampled responses by approximately 93%, with older uncompressed clients still supported.
  • Progress-aware downloads tolerate slow transfers, cancel superseded tracks, retry failures and display completed analysis promptly.
  • Relative beat-phase refinement supports eligible normal forward non-master playback. Small timing corrections are smoothed; known loops use circular correction while preserving wraps. Relative refinement excludes loops, reverse and manual motion; physical accuracy remains to be fully validated.
  • MENU can show recent waveform frame/drawing measurements and position-jump counts. iPad Safari supports launching OLC from a Home Screen icon without browser tabs or its address bar.
  • Updated Pi packaging, network capabilities, dependencies, regression checks and setup documentation.

Downloads and setup

  • Apple Silicon: OneLibraryCompanion-0.3.0-macos-arm64.dmg or .zip.
  • Intel Mac: OneLibraryCompanion-0.3.0-macos-x86_64.dmg or .zip.
  • Raspberry Pi Desktop: install both onelibrarycompanion-host_0.3.0_arm64.deb and onelibrarycompanion_0.3.0_arm64.deb.
  • Pi headless: install the host package, enable lingering and the user service, then open the Pi's network address from another device. Configure local USB mounting at boot.

Mac requires macOS 13+; Pi requires 64-bit Raspberry Pi OS Bookworm or later. Mac packages are ad-hoc signed and not notarized. Reinstall Local USB Support after updating the Mac app.

Stop players using OLC-served tracks before updating packages or restarting the host. Keep OLC running, the host awake and the USB attached during playback.
