FM: better pitch slide accuracy
...
so... it appears that pitch slides in Genesis system aren't truly linear
instead, they are "kind of linear". the frequency isn't linear, and when
it overflows the range of an octave, the high bit changes and the
frequency is shifted right

better volume slide accuracy
...
volume slide seems to be kind of quirky:
- sliding all the way down and then up suddenly sets the vol to max
- apparently there is an overflow and the slide stops when it reaches
its boundaries (instead of continuing)
