Today, I fixed my Yamaha CP70M piano. There's a bit of a string buzz on the a few lower bass strings, and the whole piano hadn't been tuned in a couple years and transport.
Let me know what you think!!

American music is an awesome store! I have so many memories of playing with the instruments in there as a teen. Glad you picked up something cool there!
Yes, you fix a buzzing bass string by twisting it at the hitch pin one twist in the direction of the winding. Very good.
Thanks Jared for letting us tag along while you tune up that piano. I liked the screen overlays of the software so we can watch them as you adjust. I liked the multiple camera angles as well.
Thanks Stephen!!
LOL DUDE! I am so hyped that I found this video! I was just trying to fix my CP-70 and all of a sudden I'm hanging with my good bud Jared again! 10/10 WOULD HANG OUT AGAIN.
Hilarious! I just sold this CP-70. RIP. They are rad though!
I will probs be in TN later this year for work, let's hang! Hope you are well.
Thanks Jared. I'm just about to tune my CP70B. Just waiting for my tuning kit to arrive from China. Your video is a great help. Thanks a lot! A year after buying mine, the MIDI model came out. I was extremely annoyed!
Good luck Pete! Let me know how tuning goes.
Using tones is how I tuned my old 1930s Wurlitzer spinet. the apps were just too laggy and it became a PITA.
Nice background music... At the beginning, you sounded like you took on a bit of a Norwegian accent there... Hei! One thing I learned is that on a piano similar to this... the strings can be tightened by winding them on themselves... Great camera angles... Always enjoy your musical talents and humor... Please record more music videos... Good job, Jared…
Thanks for the feedback, Grandma! Love ya.
Very informative ...well done video! Also love your sense of humor! Great video, looking forward to the next ones!
thank you, Dad!
It's actually a Baby Grand Piano with pickups added to it so you can hook it up to an amp. These Pianos have always been hard to keep in tune on the Bass side due to the Bass strings not being long enough, Yamaha has cleverly solved that problem by making those strings a tad bit longer.
Good to know. Thanks Oscar!
As I'm an owner of CP80 - i know that CP is extremely hard to tune well, especially bottom two octaves. Bottom part of strings You have to tune relatively higher than standard tune, and upper part needs to be tuned lower. You have really useful tab in owner's manual. And - without bumping a key - pegs will go out of tune very fast. That's a part to be great piano tuner. You have to know how hard you have to bump it and in which direction. Of course it will change tuning of this peg slightly, so you have to tune it little higher:) Lots of "and" but... this is an old instrument:)
Great so see this old piano! I owned a CP80 with MIDI, and also a Kawai EP-308.
But they simply were too spacy and heavy for mee to keep over time. I ended up with a Yamaha digital piano and I'm more than happy with it.
I currently have mine in storage, but it's quite a beast to set up!
@@jaredlichtenberg Yeah, it's a tank ;-)
The MIDI instrument almost sounds like a low bitrate mp3 in comparison to the real thing!
I have a CP80, it is SO HEAVY .
Correct! haha. They are SUPER heavy. I had to get rid of mine last year :(
Cool sound, cool tutorial to tune an electric piano!
5:39 I think the wire was wound on itself
Great J.. I wish I had known a tuning man like you for my CP, which sounds like a bbq grill 😭
Having less strings than a Standard Piano means it's easier to keep in tune and getting it tuned is a snap
Success! Great vid. Piano sounds awesome.
Thanks, friend!
I only first learned that this process was necessary when I was sixteen in 1996, around the 10th anniversary of the Sting concert documentary Bring On the Night. Near the middle, there is a scene where a piano tech is tuning up the CP-70 that was the centerpiece of Kenny Kirkland’s keyboard arsenal for that tour.
One feature of the Yamaha Disclavier line is that you can mute the harp section and just use the keyboard as a MIDI controller. Can that be done here?
Hi there - I mean you can just mute the audio output of the piano, and just use the midi output. In a stage settings you wouldn't be able to hear the piano anyway without amplification. So - yes!
It is signed by Les Mc Cann?! Nice!
Yeah! It was rented out at a show he played at, apparently back in the early 2000's. This is what the previous owner told me, anyway.
2:49 As you can see it's a True amplified Piano
I wonder if anyone out there has used the new Peterson Strobo Plus HDC Tuner as it features CP60/70/80 mapping.
5:46 The Core wire tends to buzz over time.
Do you know why it does that, Oscar? I am not sure.
@@jaredlichtenberg I guess it's a sign that the strings are starting to wear out & need to be replaced. Thankfully Mapes has the good stuff
Great Video! Cool Idea comparing the sound to the Rhodes. It seems though that you did not use a stretch tuning. Is that not necessary for this instrument?
Thank you! I have no idea. I attempted to use a real piano tuning software application before, and was more confused than anything. More than likely user error! It does tune like a normal piano though.
There is a special stretch tuning for CP pianos explained in the service manual
@@jaredlichtenberg the bass string has to be out of tuning for down and the trebel are out of tuning for high
“String in the wild”
haha! Oh yes
Am I correct in discerning you didn't use a stretched tuning for the piano? If so, how come?
did you watch the whole video? I am just curious. I am not a professional piano tuner, nor claim to be one. :)
@@jaredlichtenberg I did. And I meant no negativity-it's still a beautiful-sounding instrument after your repair and tuning work. I just noticed you tuned each string (especially the lowest and highest ones) about dead-center, and I had learned about stretched temperament from independent study and talking with another piano tuner.
@@eddievhfan1984 Oh! not negatively taken at all. I think with time, and if i still had the CP70 I would have probably figured this out at some point.
Which addictive keys vst sample are u using at the end of the video?
Hello! I used the upright piano from the Addictive Keys family of piano plugins. They also have a CP70 patch, coincidentally.
@@jaredlichtenberg imma get it. Thanks for the response
It needed a soundboard to make it sound that much thicker.
How is the midi functionality like? Is it worth getting it? Your demo sounds amazing but it might just be the plugin that over compensates the lack of pressure sensitivity with time intervals,
Hi Greg! I think it is worth finding a CP70 with the Midi function built in. It's been great to make it more versatile for sure. The keyboard does have velocity sensitivity though, if that's what you're referring to?
Jared Lichtenberg Yes, I was referring to pressure sensitivity. I was told it didn’t have it at all and that it was a simple press down. I would want to find a CP80M. Thanks for the video! It was great to see how “easy” it was to tune the piano.
@@gregdeligne2689 Thanks for watching, Greg!
Have you, by any chance, recorded any songs on that CP70M and have taken advantage of the MIDI output? I’d love to listen to any of it.
Hey Greg! I had a demo at the end of the video that shows both the MIDI out and the analog 1/4 pickup output being used, switched between then. Is that what you were thinking?
@@jaredlichtenberg Yes! I would actually love more of it in order to determine how the midi functionality holds up compared to newer midi keyboards.
@@gregdeligne2689 Wish I recorded the midi data with audio input in a separate MIDI and audio file. The keyboard is very good at sensing velocity, and seems to hold up to modern keyboards. Probably was very advanced for a midi controller of the time!
Are you sure that the midi has velocity sensitivity and that it isn't an impression from addictive keys? Thank you.
Hi Greg - Absolutely certain. I can play keys with different touch (soft all the way to loud) and it reads a velocity based on the press for each midi note.
Jared Lichtenberg That sounds too good to be true! I definitely need to get my hands on one of those pianos. 😄
@@gregdeligne2689 From what I understand, you can Midify any piano for around $2000
Who's the signature from?
Les McCann!!
what is the difference between cp-70 and cp70b?
HI there! Yes there is. The "b" stands for balanced - the CP-70B had two dual mono XLR outputs, opposed to just the 1/4" outputs of the standard CP-70.
CP-70 (1976) have the power switch at the front the AC input is like a standard 240 3 pin standard flex cable 1/4 inputs and single mono output
CP-70 B (1978) originally was just an upgraded model the power switch was moved to the r/h side /supply is a circular twist-lock pin adapter at the side to stop it coming out when hooked to a mixing desk or amp with improved pre-amp and balanced output when the bigger 88 key CP80 was introduced.
CP-70/80 D (1984) was dual mono improved pre amp and could be adapted for MIDI use although a lot of the older models could be adapted for the Forte MIDI mod - twist knobs replaced by the Graphic EQ sliders on the face panel
CP-70/80 M (1986) has now built in MIDI same format as the previous model this was also when the CP60 M was introduced which was an upright version and not as heavy as it’s bigger brother but all three CP models were discontinued not long after as the digital piano became principally an easier option for studio and live stage use.

This guys a hack. There's a lot more to tuning any piano than this especially when you loosen and re tension the bass strings. There are more tools you'll need to do the job properly.
Hey Greg! Not claiming to be a piano tuner. Do you suggest any resources that I could use next time I try to tune my CP70 more properly?
@@jaredlichtenberg See if you can get a piano tuner that knows how to tune a cp70 locally. Most do I’m pretty sure. You ask questions and stuff.
@@Dany-o3w Thanks Dany!
@@jaredlichtenberg . It takes many years to learn to tune pianos properly. A CP70 can be a challenge for experienced tuners that haven't tuned one before, because of it's small stringing scale, to get the bass sounding right. You'll need a coil lifter when you wind up a loose string. Always energise the string (play the note) first before turning the pin. If the tuning pins aren't set right when tuning it will go out of tune. That is one of the reasons why you should get a professional tuner to tune it. Electronic tuning aids are only used as a guide for professional tuners. All of the final decisions are made by ear according to the intonation of the intervals & the stringing scale of the piano.
Also the CP70 and CP80 pianos have specific tuning curves to take account of the short length and type of strings. Yamaha put the curves and tuning guidance in the owner's manual from memory.
Hey do you still own this CP70? I have questions about tuning ! Do you have Instagram ?
I no longer own the CP-70 unfortunately!
