I downloaded a copy, played with it for a while, and = sent in my very modest registration fee. Bob doesn't do a great deal of = advertising, and consequently not a lot of folks know about it. I think one of the reasons you won't find much TuneLab discussion on = the list is that there isn't a lot of people using it out there, = yet..... Dean's program has had the benefit of several years worth of Mac = testing and sales behind it, and consequently built up a clientele (like = a piano tuner would!) Now that he has released it for the PC platform = (and PC laptops are looking more and more like Powerbooks), I predict = greater success ahead for RCT. The SAT? Well, it has also been around = for donkey's years, proven its worth, and has a loyal following as well. = =20 However, TuneLab97 has some greatness built into it, namely the = flexibility of the program for customizing your tuning. As Frank points = out, you need to know how to tune to use the program. You need to know = interval checks, partial matching, (not to mention unison setting and = hammer technique... something no VTD will set for you!) So why do you = need it if you can already tune? A: to better understand what you are = doing, to analyze what you are doing, and correct and change = accordingly.=20 I use TuneLab as just that, a tuning laboratory. I was reading = Virgil Smith's article in the latest Journal about changes in string = pitch while tuning unisons. After reading the article, I set out = checking my piano with TuneLab to see how string pitches fared after = tuning, and found that the right string in octaves 6 and 7 were .02 to = .03 cents sharper than the other two strings in the unison in most three = string unisons. However, correcting the right string to the same pitch = as the other two strings left the unison sounding "wrong" (perhaps I've = become too used to natural beats...) and when I aurally "corrected" the = unison to where I was satisfied with the sound, the right string was = sitting marginally sharp again.=20 =20 The digression above is where I find TuneLab extremely useful, as = well as calculating stretch between notes based on my octave settings = and building tunings around these settings. Simple? no, but than again, = neither is trying to successfully navigate all the curves and pitfalls = that a typical piano tuning can throw at you.=20 =20 OK, Frank, as for discussion, how about the inharmonicity reading? = Do you use this to set the stretch based on the reading for one note, = such as F3 and extrapolate outwards? I've thought of trying this, but = haven't yet.=20 =20 Regards,=20 =20 =20 =20 =20 =20 =20 =20 Rob Kiddell,=20 Registered Piano Technician, PTG atonal@telusplanet.net "Windows NT crash I am the blue screen of death no one hears you scream" -Windows haiku error message ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
