sforzando is a free, highly SFZ 2.0 compliant sample player. Advanced sample hobbyists now have a powerful tool to experiment and share instruments without relying on proprietary formats. sforzando has only one instrument slot; no fancy UI, effects or mixers. Every tweak has to be done at the SFZ file level, no cheating! sforzando is also a name given for a sudden change in music dynamics which, in musical notation, is represented by the “sfz” symbol. Free As In Free Me From Proprietary Formats The SFZ Format is widely accepted as the open standard to define the behavior of a musical instrument from a bare set of sound recordings. Being a royalty-free format, any developer can create, use and distribute SFZ files and players for either free or commercial purposes. So when looking for flexibility and portability, SFZ is the obvious choice. That’s why it’s the default instrument file format used in the ARIA Engine.
