<DIV><FONT face=Arial size=2>Dave, from what I've observed, in the =
bass the SAT
will give you 6/3 octaves stretched about 1cent past pure. In the treble =
it
seems to have the stretch calculated for a pretty much pure 4/1 double =
octave.
It doesn't give you 2/1 octaves anywhere, if that's what you want you =
have to
measure them yourself ( Which can be problematic; how do you know one of =
the
notes won't drop while pulling in unisons). I've found that the SAT 3 =
increases
the stretch in the middle of octave five so much that you can easily =
have
noticeable beats in the double octaves on about six notes if you aren't =
paying
attention. For what it's worth. </FONT></DIV>
