<HTML> I don't have a clue which partials it is analyzing. However, it lists Yamaha models from the M series (small uprights) U1-U3 Series (larger uprights) C3 Series, C5 Series and CF Series if memory serves me correctly.  Also, there is a setting for the always popular CP Electric Grand Series....quite a bonus...and also on e Flat (no deviation ?) listing. The great thing about the PT100 is that a person can force the machine and the ear to agree.  It is the best machine yet designed for "independent aural use of a machine" in my opinion. You never really need to learn any of the cent deviation patterns included in the handbooks, because by merely tuning the way you usually do, and by inforcing a rigid and gradual method (self taught and come upon by practical experience) of minute cent deviation clicks of the various buttons, one can readily tune in tandem with the machine, all the while pretty much creating the tuning YOU wish to create. I have use this type of machine (in one or more of its incarnations) for decades, and I can tell you the FREEDOM makes it extremely artistic and individualistic in the hands of a pro.   Ricard de La Rosa PRO PIANO Having said all this, I must warn you that I did not go "read the back of one" to report the models listed.  The point is, it lists settings that go along  pretty much with "flat deviation", small upright deviatioans, medium through large upright deviations, small, medium and large grand deviations. They are Yamaha models, so one is supposed to figure out the approximate size of the model he/she is riding, and assign it a simmilar Yamaha model number.  Get it?</HTML>
