[CAUT] electronic tuning device preference?

[Ron Koval]

I'd like to chime in here in favor of the Verituner...
(I've used both, but prefer the pocket pc version)
 
A few years ago I led a chapter program, part of which gave me the 
opportunity to tune/sample/calculate using the 4 machines being discussed on 
the same Baldwin upright.  I limited the experiment to calculating a 
tuning "right from the box", by following the printed directions.
 
There were significant differences in the calculations from each.  I 
observed that the Verituner was the only machine that didn't end up
with a smooth curve when a single partial was graphed.  Even though 
the other machines take multiple samples to calculate the tuning, the 
result is forced into a smooth curve.
 
I did not try to use the custom functions of each to see if I could come up
with the same final tuning using any of the machines... Something for a 
future project?  
 
Any machine makes assumptions based on the information input...  At this
point, the Verituner seems to need to make the least amount of assumptions
to come up with the tuning calculation.  Being able to refer back to the 
temperament octave with actual inharmonicty data seems to give it the edge
in making the tuning match the piano.  The custom style function allows you to 
make the machine follow your tuning preferences.
 
RCT has a wicked precise pitch-raise function.  Tunelab allows for muteless(!)
large pitch raises.  The SAT battery lasts forever and is very durable.
 
RCT, Tunelab and Verituner all have internet forums to allow techs to 
communicate with each other about specific issues and questions.
