Yamaha CS80

Ok, I'm pretty sure that I'm the first person to ever tune a CS80
using a cell phone!  I tuned one this afternoon using the mp3 files I
created. I popped them on the SD card in my Treo, set a file to
repeat, and tuned the Yamaha against the nice, stable sine wave.
Worked like a charm.

Tomorrow I'm installing a Kenton MIDI kit in a different CS80. To make
the install a bit cleaner, and reduce people's horror at me drilling
into the front panel, I'm going to mount the switches and MIDI jacks
inside the power-cord compartment. No mods to the outside of the keyboard!
