Not quite sure how to indicate multiple packages as a single change in the squeak process, so doing it how I'm used to.
Sorry.

It essesntially changes sound to use pragma-based preferences.
Old accessors in Preferences have been deprecated.
Not sure what to do about the default preference vaulues of themes, they do not seem to load in values for pragma-based preferences correctly.

This package contains the modified packages as prerequisites, and a postscript removing the old preferences.

(Or it should, I can't actually see them anywhere...)
Just in case, they are: 
EToys (hsj.81)
Morphic (hsj.518)
MorphicExtras (hsj.100)
ST80 (hsj.124)
Sound (hsj.28)
System (hsj.416)
