ETDs vs exam and master tunings

[Andrew and Rebeca Anderson]

Regarding Verituner requiring more than one pass to refine its calculations:
When a piano is way below/above the desired pitch the calculated 
stretch does not always come out right.  I always figure two passes 
for a pitch-correction.  The close-to-pitch, fine-tuning pass is the 
one where things come out right for me.  With over-pulls it is hard 
to test the stretch anyway, at least it is until you have gone past 
several notes.  It is interesting to measure and see that dimple you 
are pushing across the sound-board when you re-tension a piano.

I chose the Verituner because I distrusted calculated stretch 
profiles, especially on marginal instruments.  I started using a 
Peterson 490ST and as I developed my ear and aural tests I had begun 
to tweak the stretch profiles as I went.  Eventually I decided to get 
an instrument with better tuning abilities and especially the ability 
to measure tunings and to grade them.  Now I can practice the aural 
test and grade my efforts.  It has been an eye opener.

On the Verituner you can choose your desired degree of stretch and 
tweak the "weighting" too.  The note's own partials are used to fit 
it into the desired stretch.  Scaling breaks are well accommodated. 
I've argued with the machine's compromises several times only to 
return to it aurally.

What I don't like: 	Size.
			It won't let me calculate over-pull from more than ~40 cents 
away.  (You can change the base pitch you tune to.)
			The auto-note function doesn't work well on large 
pitch-corrections, doesn't have a foot pedal like the Peterson.
