Introduction to sforzando

Free As In Free Me From Proprietary Formats

SFZ Text File Example

Example SFZ File

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.

Open for Business… or For Fun!

OEM developers and sample providers are offering a range of commercial and free sound banks dedicated to sforzando. Go check them out! And watch that space often, there’s always more to come! You are a developer and want to make a product for sforzando? Contact us!

As a bonus, an integrated format converter should get you started!

You can also drop SF2, DLS and acidized WAV files directly on the interface, and they will automatically get converted to SFZ 2.0, which you can then edit and tweak to your liking!

Powered by the ARIA Engine ™

ARIA Engine sforzando relies on the same ARIA Engine that powers the ARIA Player and other products from Garritan and obviously Plogue chipsounds. This engine has been built from the “ground up” on the SFZ spec, and not as an afterthought. Like the other ARIA products, this player is available as a standalone and VSTi/AU/RTAS/AAX plugin on Windows or OS X and can run in either 32bit or 64bit.

Dedicated To Its Community

Sforzando LogoBy releasing this free player, we hope to improve the adoption of this open standard. Plogue has deployed a forum dedicated to the SFZ format to help users support each other.
