Computer system requirements:
Below are the minimum computer-system requirements for UC Surface.
Apple iPad
• iPad® Air, iPad mini with Retina display, iPad (4th generation), iPad mini, iPad (3rd generation), or iPad 2
• iOS® 7.03 or later
Mac
• Mac® OS X 10.8 64-bit or later
• Intel® Core™ 2 Duo processor (Intel Core i3 or faster recommended)
• 4 GB RAM (8 GB or more recommended)
Windows
• Windows® 7 x64/x86 SP1, Windows 8 x64/x86, Windows 10 x64/x86
• Intel Core 2 Duo processor (Intel Core i3 or faster recommended)
• 4 GB RAM (8 GB or more recommended)
Mac and Windows Systems
• Wired or wireless network connection
• Internet connection
• For Capture™ and Studio One®:
• FireWire S800 (IEEE 1394b) port
• Internal or external 7200 RPM storage drive highly recommended
• Monitor with 1280x800 resolution
• 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.
