- Intel Core Duo processor (Intel Core 2 Duo or Core i3 or better recommended)
- 4 GB RAM (more recommended)

Windows:
- 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)
- 4 GB RAM (more recommended)

Mac and Windows Systems:
- FireWire S800 (IEEE 1394b) port
- Ethernet port recommended
- Internet connection recommended
- DVD-ROM drive
- Internal or external 7200 RPM storage drive highly recommended
- Monitor with 1280x800 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 Mac should be no lower than 1280x800 pixels. Known compatible and incompatible hardware
