Computer system requirements:

Below are the minimum computer-system requirements for your FireStudio Tube.


  • Windows XP, Vista, Windows 7 (32- and 64-bit)
  • Intel Pentium 4 1.6 GHz processor or AMD Athlon 64 3000+ (Turion) (2.8 GHz or faster recommended)
  • 1 GB RAM (2 GB or more recommended)


  • Mac OS X 10.6 (Snow Leopard) or later (32- and 64-bit)
  • Intel Core 1 Solo 1.5 GHz processor (Intel Core Duo or Intel Xeon processor recommended)
  • Apple M1 Mac (Apple Silicon Series) not supported
  • 1 GB RAM (2 GB or more recommended)

Windows and Mac Systems

  • IEEE 1394 FireWire 400 Port
  • Internet connection recommended
  • DVD-ROM drive
  • Internal or external 7200 RPM storage drive highly recommended
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) that you might experience while monitoring audio or MIDI signals.
Monitor resolution for both PC and Macintosh should be no lower than 1024x768 pixels.
