Using a frequency counter to tune a musical instrument is almost always 
a really bad idea.  All you need is a good, stable tuning reference, 
preferably a sine wave A-400.  If you have decent ears, you can do all 
the CS80 tuning steps with this, just listening to beat frequencies. 
Different octaves would make it a bit easier.  Say - finally a good use 
for a DX-7 :^)
