After a little further investigation into the IFF 8SVX format, I find that
it apparently DOES provide for envelope information.  Still, the SoundScape
manual explicitly states that no envelope is saved when you do an IFF save
with their software.  My guess is that some developers are lazy and may
only implement a minimum version of IFF.  In addition, the 8SVX standard
implies that you would use multiple 8SVX types to achive different instruments
on each octave.  This implies that the features I'd like to see CAN be
done within the IFF format, but again, maybe some developers are too lazy
to use the standard.  It's unfortunate that the IFF image standards are 
being so widely adopted (to the benifit of us all in a myriad of ways)
yet the IFF sound standard may be falling throught the cracks.

In fact, after closer investigation of the IFF spec, MOST of the required
features are documented, though the restriction of all octaves being
multiples (i.e. low octave = 400 samples, next = 200 samples high = 100
samples etc.) does appear to hold.  I can't imagine WHY such a restriction
might exist.  Still, a standard that is not being used is as good as no
standard (sigh).
