  Note: 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 signals.
