Is it normal for a cp70 to have tuning issues?
I'm not familiar with the actual instrument, but all of the samples I have heard are out of tune. Some very badly.
Sometimes it's this note out of tune with that note, and sometimes it's one note out of tune with itself, like a piano having 3 strings per note and them not being all tunes together.
Are there sample sets that are in tune or is that technically impossible because of the nature of the instrument?

There is a cp70b sitting about 30 feet to my right and it is my pride and joy.

AFAIK, you can tune a CP-70 with a standard piano tuning hammer. It doesn't have to be Yamaha brand. Go to any old-style piano store.

I got the equipment and know how to tune it on a regular basis. In my opinion that is why they got a reputation for having that beat up honky tonk sound.
Because the bass strings were so short they never could tune properly

The piano tuner I used on mine has a lot of experience with CP70/80s because he was called in to tune CPs locally when some band strolled into town with one for a big gig and he had a lot of business in the 70s and 80s tuning the CPs of the greats.
It seems they have to be 'compensated for' in their tuning. 'Proper' pianos have two strings per key on the bass end and three on the mids and uppers whereas CPs have one string on the left and two on the right. Not just that but the strings are considerably shorter. Tuning them to 'perfection' doesn't work apparently - you have to play with it, compromise, listen and tease it into sounding 'right' overall rather than tuning fork perfection ... not unlike tuning a 'real' piano but even more so, especially the CP's short, flabby bass strings.
The trick, perhaps, it to treat them as an instrument in their own right with a unique sound rather than an electric Steinway concert grand.
Cheers,
Steve
