Dear colleagues - Here in New York City (and in my previous work at Berklee College of Music in Boston), pitch raising is (was) a commonly encountered necessity. I've had the most success in achieving _great_ one pass results by using the new Sanderson AccuFork II. With its tunable frequency slider and volume controls, as well as its 4 chromatic sounding notes (A - A# - B - C) the device assists me in attaining really splendid results. I'm very much an aural tuner - using the Baldassin/Sanderson temperament as much as possible. Following the pitch raise instructions that came with the AccuFork II, one can analyze easily the amount of required over pitch - generally 1/3 above A440 as compared to the total amount flat in cents. I then set a quick, accurate temperament, and the results are always incredibly precise. No guessing is involved. The AccuFork II is a truly efficient, magnificent assistant and is a real pleasure to use. The final tuning is invariably a simple matter of further adjustment. So many of the temperament intervals, as well as the octaves throughout are so astonishingly close to correct after the pitch raise that it's truly uncanny. I also quickly check the initial flatness of the bass strings with the AccuFork II. If they are not as flat as the plain wire, then I won't over pitch them as much as the plain wire.
