The reason why Studio One resonates with musicians is simple: PreSonus listens. Many new features in Version 4 are the direct result of user feedback, including AAF import/export so users can bring song data from their old DAW into Studio One. Add the most flexible arranging tools of any music program, full integration with Notion for superior notation, over 20 GB of carefully curated content, analog console emulation, advanced step sequencing, unified hardware control with the FaderPort series of hands-on controllers, and much more—it’s no wonder that Studio One continues to gain new followers every day.
