b30c5679ae genesis: reduce CPU usage

so we just run the chip 6 times and output at 1/6th the rate, which

b2908413fe 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

9736b77401 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)
