Studio One Professional features a 64-bit floating-point version of this audio engine that automatically switches between 64- and 32-bit operations on the fly to accommodate 32-bit plug-ins. This means you always get the sound quality and blazing speed.
Studio One Artist and Studio One Producer features the same audio engine but it always operates in 32-bit mode. It recognizes your PreSonus interface, and preprogrammed templates automatically create software inputs and assign them to the appropriate hardware inputs on your PreSonus interface. You don't have to configure your software to work with your hardware. Studio One stores I/O configurations with each song, for each computer, and for each device driver. As a result, you can take a song to a friend's studio, use Studio One with their interface, and when you get back to your studio, Studio One will recall the original I/O configuration for the song, as if you never left.
