This product has been discontinued.

NOTE: QMix and SL Remote have been updated to support iOS 11. These changes also require an updated version of Universal Control. Please see this link for more details.

Computer system requirements:

Windows

  • Windows® Vista x64/x86 SP2, Windows 7 x64/x86 SP1, Windows 8 x64/x86
  • Intel® Core™ Duo or AMD Athlon™ X2 processor (Intel Core 2 Duo or AMD Athlon X4 or better recommended)
  • 2 GB RAM (4 GB or more recommended)

Mac

  • Mac® OS X 10.6.8 or later
  • Intel Core Duo processor (Intel Core 2 Duo or Core i3 or better recommended)
  • Apple M1 Mac (Apple Silicon Series) not supported
  • 2 GB RAM (4 GB or more recommended)

Windows and Mac Systems

  • PreSonus Universal Control 1.5.3 or later
  • IEEE 1394 FireWire 400 Port
  • Internet connection recommended
  • DVD-ROM drive
  • Internal or external 7200 RPM storage drive highly recommended
  • Monitor with 1024x768 resolution
The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.
Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio or MIDI signals. Monitor resolution for both PC and Macintosh should be no lower than 1024x768 pixels.
