SFZ v2 #

The SFZ v2 standard has never been clearly set down anywhere. For the purpose of this website, anything included in the SFZ v2 regression tests is considered SFZ v2, regardless of which SFZ players it might or might not be actually implemented in. If something works in both ARIA and Cakewalk, then it’s also considered SFZ v2 on this website, though it might not be an official, de jure standard. If something works in a Cakewalk product, such as Rapture, but not in ARIA that’s considered a Cakewalk extension. If something works in ARIA but not in any Cakewalk products, that’s considered an ARIA extension.

The book is not recent, and was not intended to be a standards document, but rather a manual for users of Cakewalk products. So, if you are developing a new SFZ player, do not feel obligated to support all opcodes in this list - instead, use your judgment.

ARIA #

ARIA also adds some extended MIDI CCs in addition to those already added by SFZ 2, and XML instrument banks as a way of organizing multiple SFZ instruments and configuring graphical user interfaces. See also the Plogue forum’s ARIA’s Custom opcodes post.
