Polyphone
Polyphone is a free, open-source soundfont editor for macOS and other platforms. It lets users create, edit and manage soundfonts—digital audio instrument libraries that define how virtual instruments sound in music production software, synthesizers and audio workstations. Musicians, composers and sound designers use Polyphone to customize existing soundfonts, tweak instrument samples, adjust ADSR envelopes, add effects, and export their creations for use in DAWs, samplers and notation software. The app provides both a graphical interface and command-line tools for soundfont manipulation.
AI Recommendation
1 suggestionWe could not confirm whether a native Apple Silicon build of Polyphone exists. The most recent search result available points to version 2.3.1, but does not indicate the architecture. Polyphone is maintained as an open-source project, so your best next step is to check the official Polyphone project repository (likely on GitHub or a similar forge) to see if a native arm64 build has been released or if one is planned. If you rely on Polyphone for music production, contact the maintainers directly to ask about Apple Silicon support and a timeline, since any Intel-only build will stop launching on macOS 28 when Apple removes Rosetta 2 in September 2028. Until then, your current copy will continue to run under Rosetta 2, but you should plan accordingly.
