Cakewalk SFZ v2 Opcodes

These opcodes have not been implemented in any currently available SFZ player, to the best of the author’s knowledge. They are included here for the sake of archiving all available information.

Note that modulations such as (on)ccN, and vel2* opcodes are included in the pages describing the parameters they modulate.
