Since there seems to be some confusion from others about whether I answered this before or not, of course you notice changes, you play octaves as you go and do some checks to make sure you know what's going on. Just like Ronald Reagan said with respect to SALT, trust but verify. As you tune up in the scale you drop in the octave note below to check or if you are tuning down you play the octave above, not difficult. If the heat has come on and changes things then you can either recalibrate using the offset or (is it possible for an ETD user???) tune by ear-what a concept! Let's keep a perspective here. Just because you have the machine on doesn't mean you're clueless about how to handle contingencies or can't choose to ignore it. This notion that ETD users suddenly go deaf is surprising. Tell me then, as an aural tuner, if you go back after doing an aural tuning and notice that the piano seems to have drifted some perhaps because the heat cycled on and off and on and off. and influenced, maybe, some section of the piano that you weren't involved with, how do you know which part of the piano is off pitch and should be corrected? With an ETD you could quickly go through and measure to see where the drift has occurred and make a decision about what to correct based on real information, not a random estimation. David Love www.davidlovepianos.com Do you ETD users notice these changes? And, if so, how do you compensate for it? Do you play octave combinations below the note being tuned to see what's going on below it? Do you alter the tuning program with an offset of some kind? If you offset, how does the program keep up with various offsets? Say, if the heater stops blowing, do you then reconfigure the offset? -- JF -------------- next part -------------- An HTML attachment was scrubbed...
