ⓘ SFZ (file format)

SFZ is a plain text file format that stores instrument data for software synthesizers. The SFZ format was developed by Rene Ceballos and is now maintained by Cakewalk. SFZ is a royalty-free format and can be used by software developers for both free and commercial purposes. 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.

Similar file formats are proprietary standards for native instruments Kontakt.NKI.NKM.

A simple example of the file SFZ:

lovel=0 hivel=127 trigger=attack pitch_keycenter=60 lokey=30 hikey=61 sample=SubDir / 01C4.wav trigger=attack pitch_keycenter=62 lokey=62 hikey=63 sample=SubDir / 02D4.wav trigger=attack pitch_keycenter=64 lokey=64 hikey=64 sample=SubDir / 03E4.wav trigger=attack pitch_keycenter=65 lokey=65 hikey=66 sample=SubDir / 04F4.wav trigger=attack pitch_keycenter=67 lokey=67 hikey=68 sample=SubDir / 05G4.wav trigger=attack pitch_keycenter=69 lokey=69 hikey=70 sample=SubDir / 06A4.wav trigger=attack pitch_keycenter=71 lokey=71 hikey=71 sample=SubDir / 07B4.wav trigger=attack pitch_keycenter=72 lokey=72 hikey=73 sample=SubDir / 08C5.wav trigger=attack pitch_keycenter=74 lokey=74 hikey=75 sample=SubDir / 09D5.wav trigger=attack pitch_keycenter=76 lokey=76 hikey=108 sample=SubDir / 10E5.wav

The sfz format is accompanied by a separate company or group, and supported features may vary between the individual synths. Official page on the ease website is no longer available; however, the description of SFZ opcodes can be found on various websites.

There are applications that provide point-and-click interface for creating file PPS, alternatively, to edit the text directly.
