Yamaha PTII

[Tom Dickson]

Hi, Kevin,

   In Randy Potter's course notes, a number of years ago, he addressed the 
issue of preset tunings on the Yamaha PT I.

   As I recall, his advice was that for the bass on many pianos, one could 
go into the Vernier mode (spelling ?) and after F33, below,  subtract one 
step which would be 0.2 cents for each note  on that machine's curve.  He 
felt that this would give an acceptable bass for N. Am. market pianos.

   Obviously, one would need to add aural checks to this to make sure that 
the transition was smooth.  However, it might be a start with your 
compatriot.

Sincerely,
Tom Dickson
