actually, now that i know a bit more about the problem, how do you account for the
zero slope at the endpoints of gen8?  this warp on the ends accounts for some
distortion.  i think gen8 doesnt make very good sine waves.

personally, when using sine waves in f tables, i prefer to use large sizes, such
as 8192 or 16384.  this greatly minimizes the need for interpolation.  but i still
use oscili over oscil.  and if oscil3 sticks around, i will probably continue to
use it.

(is that the kind of info you were looking for, john?)
