I have been using Studio One since high school when it was just Studio One. I loved it from the first time I started using it and realized it was the easiest, most intuitive DAW on the market. It has been my only choice for a DAW since I started. It is so useable that I went almost 5 years without upgrading from the original Studio One Artist. Once I upgraded it became even more useable, even with the vast amount of instruments and effects. Studio One 4 Professional is by far, the best version PreSonus has released. Everything is so much more streamlined, customizable, and easier to use. If you are thinking about switching to a different DAW and need something that is absolutely top quality, get Studio One 4.
