Yamaha CS80

Hello Frederik

thanks for the welcome!


> to do this mod. I about to tune my CS80 now, so that was good timing!
Do you tune with a frequency counter or with a chromatic tuner?

Until now I had no frequency counter, so I used a guitar tuner with an 
analogue meter (Boss TU-12). I first adjusted the octave scaling only 
until the needle doesn't jump and I did not care for the absolute 
tuning. After that I set the absolute tuning.
This is a very fast method with a "normal" analogue synth, but with the 
polyphonic CS series lacking an unisono mode it is a bit annoying.

I now have a multimeter, which can do frequency measurements too, so 
I'll try it this time with the "official" method from the service manual.

On the other hand, I have already thought about establishing a kind of 
unisono mode, but that is too much effort for now...
