NotePerformer vs Surge XT

NotePerformer enhances playback in Sibelius, Dorico, and Finale notation software with its own large-scale modern symphonic orchestra sounds. It analyzes scores and performs instruments with natural musical phrasing; the maker describes its virtual instrument technology as patented and developed in-house. The software runs on macOS and Windows and has a 30-day trial. During that trial, the notation software must restart every hour, audio export to disk is unavailable, and the trial ends after 30 days. A single-user perpetual license costs $129 as a one-time purchase, including EU VAT, and permits use on as many computers as desired. Single-user rent-to-own costs $10.75 a month, including EU VAT; after 12 consecutive months it converts to perpetual, with offline use up to 14 days. A site license costs $200 as a one-time purchase for 1–5 seats. Listed compatibility starts at Sibelius 7.1.3, Dorico 3.5, and Finale 27 (English).
