// OPZ supports a "fixed frequency" mode for each operator, with a 3-bit
// range and 4-bit frequency value, plus a 1-bit enable. Not sure how that
// works at all, so it's not implemented.
// note by tildearrow:
// - I have verified behavior of this mode against real hardware.
// after applying a small fix on the existing early implementation, it matches hardware.
// this means fixed frequency is fully implemented and working.
//
// There are also several mystery fields in the operators which I have no
// clue about: "fine" (4 bits), "eg_shift" (2 bits), and "rev" (3 bits).
// eg_shift is some kind of envelope generator effect, but how it works is
// unknown.
// note by tildearrow:
// - behavior of "fine" is now confirmed and matches hardware.
//
// Also, according to the site above, the panning controls are changed from
// OPM, with a "mono" bit and only one control bit for the right channel.
// Current implementation is just a guess.
//
// additional modifications by tildearrow for Furnace
