As with previous iterations, Studio One 5 comes in two versions: the top-tier Professional edition and the far cheaper, lower-spec Artist edition; but for this review, we’re only looking at Studio One 5 Professional - see the PreSonus website for more on Artist.
We should also point out that you can buy Studio One 5 outright or as part of the new PreSonus Sphere subscription service. This gets you all the company’s software (Studio One Professional and all its plugins, Notion, and a ton of sample-based instruments and loops), and various collaborative and networking tools, for a monthly (£12.05) or annual (£132.97) fee.
