[CAUT] Steinway stretch (was Re: Steinway Verticals)

[David Ilvedson]

There can be a lot of different stuff happening between one tuning style and the next but you have to have stable unisons.   
That is why I really love my SAT III.   Except for the tweak here and there, when concerned about single and double octaves (which is often SAT III placement, ie. what it is reading...moving it around to check for for correct reading), I'm mostly concentrating on unisons and stablility.    The changes to TUNED notes as you progress through a tuning would probably startle many strictly aural tuners...IMHO
