I mostly use Studio One Pro 7 for mastering, and it’s become my main tool for finishing tracks. The layout is clear, the workflow is quick, and the built-in tools (especially the mastering/project workflow, metering, and export options) make revisions and final deliveries painless. It stays stable even with heavy chains—EQ, compression, saturation, limiting, analyzers—without feeling sluggish. I also like how easy it is to keep multiple versions and bounce out exactly what I need. Overall it feels polished, modern, and genuinely professional. Highly recommended.
