General System Optimizations

Windows: System Optimization For PCDJ Software

Version History

DEX 3.20.7 RE Changes

  • New controller: Hercules DJ Control GLOW
  • Fixed crash when using certain 4-deck controllers
  • Added support for multiple identical controllers (eg. single-deck controllers such as the Reloop RMP-4)
  • Automatically assign identical controllers to different decks
    – you can view in Options -> Control which decks are assigned to which controllers
  • Performance optimization’s (we store a pre-scanned default controllers list in the user’s Controllers folder – this is much faster, especially on slower machines which took 1-2 seconds to load the scripts list every time the app was started)
  • Controller scripts/mappings: setAudioDevice() function now also (optionally) has audio routing settings; example: setAudioDevice(‘audio device name1|||audio device name2|||name3|||etc’, ‘optionalSetting1:0|||RoutingOutDeckA:1|||RoutingOutDeckB:2|||etc’);
  • Various Bug Fixes and Performance improvements

DEX RE Changes

Please note that on Windows you can only control the latency for ASIO, WASAPI latency is controlled by the OS itself (usually about 22 ms) and cannot be adjusted (it’s fixed).
