This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment The Cybertuner does have the best pitch raise function, in my opinion. The VT is next best and the SATIII is functional but must be recalc'd every so many notes. The Cybertuner calculates the overpull based on a trailing average of 5 notes, I believe. Each section does vary in terms of % overpull and I would be curious to know what the default settings are. If the goal is to end up at A440 within a reasonable number of passes (like 2), overpull is necessary.

Up to pitch. 2nd pass up to pitch and 3rd pass in the tenor and leave where it lies.

On small spinets, reduce the numbers by 5% each. Do unisons as you go." David, I must take exception to this technique! Although, it will work most of the time on most Olde Uprights and Grands, there is always the exception. This technique is archaic, to say the least. There are better ways. The 32% in the upper treble will most likely get someone in a world of hurt! Most strings, in that area, are already at/above 50% of their breaking strength!!! You raise it another 32% and strings will break, IMO. I've done some studying on the subject and wrote an article for the PTJ, in Dec. 1999. Regards, Joe Garrett, R.P.T.
