Yamaha CS80

Hi all.

After my last CS80 tuning (and with a few more coming up), I thought
of a way to make tuning the beast easier and faster and not even
require test equipment (although that makes it a little easier).  The
tuning procedure requires one to tune the highest A in the highest
octave (2-foot) range and then the lowest A in all four octave ranges.
I just created mp3 files of sine waves for each of these five
frequencies using SoundForge. 

The files are in the Files section (duh...) under folder "Tuning
tones"
(http://launch.groups.yahoo.com/group/yamahacs80/files/Tuning%20tones)
 Just play the files in repeat mode on your favorite device. If you
have a good ear (and wide-range speakers/headphones) you can do the
tuning completely by ear, just using beats. It's a little easier,
especially on the highest and lowest frequencies, to use a cheap
oscilloscope. See my post from a couple of months ago
(http://launch.groups.yahoo.com/group/yamahacs80/message/1452) for the
details.

Please let me know if this is works well for you.
