...
by just forwarding an output buffer to the dispatch and begin/length,
the number of calls may be reduced which improves performance.

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

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)
