PolyPhontics

PolyPhontics is a powerful sampler instrument editor for macOS. Create, edit, and convert sampler instruments across five industry-standard formats — all in one app.

IMPORT & EXPORT

• SoundFont 2 (SF2)

• DLS (Downloadable Sounds)

• EXS24 (Logic Pro Sampler)

• SFZ (open sampler format)

• DecentSampler (.dspreset)

Full round-trip support means you can import from any format and export to any other. Convert your SFZ libraries to SF2, turn Logic instruments into DecentSampler presets, or build new instruments from scratch.
