 ## 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 Simon Cann's [Cakewalk Synthesizers] is not a recent book,
-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] listed in this website -
-instead, use your judgment.
