PolyPhontics opens, edits, and converts sampler instruments across five formats — SF2, DLS, EXS24, SFZ, and DecentSampler — all in one native Mac app.
Whether you're converting a legacy SoundFont library to DecentSampler, building EXS24 instruments for Logic Pro, or inspecting a DLS file, PolyPhontics handles the full round-trip.
