tuning

[Oleg Isaac]

Michel,

The Sanderson-Baldassin is a wonderful tool, I have used it on many
pianos, in fact I always refer on some part of it because I extend the
temperament from F4 A3 A4 to A2, then install all thirds to be sure of
my FAC center part, ort to put me on the way to correct the SAT

It is complete in the PACE tuning lessons #2 - You can ask it at
Inventronics if you dont have it in the SAT II manual. They propose to
mail it to you if you ask.
I had a french translation somewhere, but the explanations where not
really complete as in PACE. 
Sorry my fax is computer-based so I can't fax it as it is.

Regards
Isaac
