Scaling 101

[Stéphane Collin]

Hi Mark.

I like the papers of Paul Poletti about scaling.  I find his system of
converting all scaling parameters in the relative form of semi-tone
equivalents very clever and useful : this is both more intuitive and more
precise than a usual graph.  Here is the link :

I have also a very good paper of Michael Latcham exposing the problems of
scaling in an easily understandable (generous) form.  This is not on line,
so if you would like it, just ask.

Stéphane Collin.
