d6fb6b0bb3 more optimization 
as of now non-stereo sound chips are only processed once

6efcfc2e8a prepare for possible major optimization 
by just forwarding an output buffer to the dispatch and begin/length,
the number of calls may be reduced which improves performance.

b30c5679ae genesis: reduce CPU usage 
the chip uses TDM to output the channels one by one
so we just run the chip 6 times and output at 1/6th the rate, which
means less work for blip_buf and less C++ overhead

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)

67847d79cf attempt to fix the volume slide mess 
also a fix to noise arps in basic mode in SMS

the volume slides will be an adventure as the behavior seems to be hard
to determine
