I think the other problems mentioned in the original mail have been
addressed, but I have a guess about the amplitude problem, which I don't
think I've seen a reply to.  I think the key bit of information is that
this is being run on a Macintosh.  The Mac version of Csound has a very
handy feature (that I use all the time) of being able to write a
floating point file, and then scale it in place to 16-bit integers.  My
guess is that this option is selected, so that the final output is
scaled the same, no matter what the intermediate floating point output was.
