sfizz project

A free, open-source SFZ player with AU, VST3, and LV2 builds across every platform.

sfizz is a free, open-source SFZ player and C++ library. It focuses on efficient, standards-based SFZ playback and ships as AU, VST3, and LV2 plugins plus a JACK client, which makes it the go-to SFZ player on Linux as well as macOS and Windows.

Because it is open source and cross-platform, sfizz is a safe long-term home for an instrument you want to keep usable for years, on any system.

File format and compatibility

Export an instrument from SampleStack as SFZ and open the .sfz file in sfizz. Keep the referenced WAV files in the same folder and your zones, velocity layers, and loops load as written. For Linux and LV2 hosts, sfizz is usually the most reliable way to play a SampleStack SFZ export. The SFZ export page covers the details.
