Yamaha CP40 Review

Everybody knows Yamaha, not just for musical instruments, but for other kinds of products like motorcycles. Yeah yeah we know, motorcycles and keyboards have only very little in common. But anyway, we are not here to talk about motorcycles. We are here to review the Yamaha CP40.

The Yamaha CP40 belongs to the CP series which is where Yamaha has its line of stage pianos. And this series was first introduced in 1976. So, that means the CP series have been around for over 3 decades. And since then, many musicians have actually enjoyed these keyboards from their reviews online.

Today, we get into the nitty-gritty of this piano to find out if this keyboard is worth your time and money. So, without further ado, let’s get to it.

The Bottom Line For Those In A Hurry…

Not everyone might have the time to go into this review. And that’s why we have decided to throw in this bottom line section. So, what’s the bottom line on the Yamaha CP40?

It is great but it is definitely not perfect. Well, nothing ever is but seriously this isn’t perfect. The CP4 is obviously a lot better (also read “more expensive”) than the CP40. However, the CP40 also works if you can’t afford the CP4 right now.

Alright, first for the good. The Yamaha CP40 is obviously high quality with a high level of playability. Plus, it is very lightweight. However, this piano is more of a jack of all trades than a specialist.

So, even though this keyboard comes with enough sound effects to dress your sound up nicely, a pro player will still need a lot more.

So, for the pro players, you might be better off with a Nord.

With a Nord, you’ll be able to take control of drawbar organ sounds, and load new character pianos onto your keyboard. Also, you’ll be able to get topnotch half-pedalling, as well.

The Yamaha CP40 will not offer you all that.

You could also try the Roland 800 if you’re big on getting something more sophisticated.

And now to the full review for the more patient ones around…

Features Of The Yamaha CP40

Alright, getting to this phase means that you want to get to know the Yamaha CP40 a little more. And so we obliged and here we are. Check out the features of the Yamaha CP40.


The Yamaha CP40 is an 88-key keyboard and so most pianists will find this sufficient. However, even with 88 keys, this keyboard still feels pretty lightweight and compact. So, it will definitely make the piano easy to carry around.

The Yamaha CP40 is definitely the traveling musician’s buddy. So, storage or travel, the Yamaha is one convenient instrument.

The keys on the CP40 feel somewhat realistic. And, of course, the CP40 comes with Yamaha’s Graded Hammer keyboard. This makes the keys of this keyboard feel almost as real as an acoustic piano. Well, only in that it comes graded. And by graded, we mean that the higher ends feel lighter but the lower notes feel heavier.

This keyboard does not come with the Natural Wood Graded Hammer that the CP4 has. So, naturally, it doesn’t feel wooden. Plus, it does not come with ivory keytops. So, we can’t say playing this would be absolute bliss.

But hey, the keys still feel decent. A little plasticky, of course, but you could say it does feel somewhat high end.


The Yamaha CP40 does well in the sound department with the expected downers here and there.

For one this is a very playable keyboard and it comes with a beautiful sustain too. Plus, you could also say that this keyboard is very responsive with an impressive range as well.

On the Yamaha CP40, you’ll find 15 CFIII Grand Piano sounds. These piano sounds represent a collection of quality piano sounds as made by Yamaha. They work great for large performances and are an ideal choice for all kinds of music genres.

From pop, to country, to rock, the CP40 will deliver on that.

Also, for classical players, there are the S6 and CFX piano sounds. These sounds will help you achieve symphony orchestras, soft vocals, as well as ballads.

Now, in all honesty, we must say that the CFX could sound a little better on stage. It does tend to veer into the “not-so-persuasive” arena a bit. But you could add some reverb to compensate for that.

And in addition to these, the Yamaha CP40 comes with 247 voices which include the basses, strings, organs, pads and others. And let’s not forget the voice library which Yamaha built based on the MOTIF Synthesizer.

So, musicians will find it very easy to draw inspiration from the large sound pool available to them.

Sound Effects

Of course, there are enough sound effects for you to touch up your sounds. Adding them up, they sum up to 62 Virtual Circuits Modeling (VCM). And these effects include reverb, compressor, chorus, as well as a 3-band Master EQ.

And for even more unique sounds, you have the layer and split functions. The Layer function allows you play different voices at once like piano and strings or piano and organ. While the Split function splits the piano into two, so you can achieve two separate sounds on each half of the keyboard.

It would have been a huge downer to have so many functions, features and sounds with a dreadful interface. Thankfully, the Yamaha CP40 has none of that. The user interface is actually quite intuitive and helps to access the functions of the keyboard very easily.

If you’re at a performance where the stage isn’t quite properly lit, the CP40 will be your best buddy. The buttons are large and not just that, they are also lighted. This can be a life saver in so many ways.

As for accessing sounds, the Yamaha CP40 kinda makes it easy. There’s a Category Select menu from where you can access all your sounds pretty easily. This is a very important feature for an on-stage piano. You want to be able to locate all your functions easily and quickly – your performance depends on it.

And then, there’s the magic Main Solo button. And you can probably guess what it does. With a tap of this button, you can easily get back to playing full piano across the keyboard.


So, so far we have no problems with the interface of this keyboard, and you shouldn’t either.

And, of course, we can’t fail to mention that this keyboard looks elegant and simple in its design.

Pros Of  Yamaha CP40

  • The CP40 comes with 15 CFIII Grand Piano sounds and 35 Vintage electric piano sounds as well.
  • There are 24 voices, 297 presets, and 62 VCM effects to get the player inspired.

  • Layer and Split functions present.

  • Compact, lightweight, and portable.

Cons Of  Yamaha CP40

  • The organ sounds on this keyboard aren’t quite doing it for us.
  • This does not come with on-board speakers.
  • It does cost quite the pretty penny.
  • In the eventuality that there’s a sudden or extreme temperature change, you could experience a little problem with condensation on your instrument.

And with that last epiphany on the cons, the next question should rightly be…

How Do I Take Care of My Yamaha CP40?

Now, you’ve got to be careful with the way you handle your CP40. Because it is portable, there will always be that temptation to just drop it anywhere. But you, friend, must resist it.

Always ensure that you do not keep it in any place where the keyboard can experience a sudden temperature change. If you do that, you risk exposing the keyboard to condensation.

Now, if by chance, your CP40 happens to stay in a place with a subzero temperature or a place that’s over 100 degrees, you’ve got to be careful. Especially when you move into a new environment, you’ve got to take things gradually.

Don’t suddenly expose your piano to the new temperature, instead, make the transition gradual. This way, you avert the risk of condensation building up in your keyboard.

1 thought on “Yamaha CP40 Review”

  1. This is a good, fair and balanced review and I’ll happily second its main findings.

    The CP-40 is the in-house piano at one of my weekly residency gigs and I find it reasonably pleasant to play. It’s not outstanding but it’s certainly very satisfactory.

    For my own part, I’m really only interested in the piano sounds – because that’s what my gig is about – so I’ve nothing important to say about the other features and sounds other than that I briefly checked the electric piano sounds and found them quite appealing;
    strings, pads and choir voices are not my bag;
    my personal take is that drawbars are an integral part of an electronic organ and I find it too frustrating to play organ sounds that I can’t modify on the fly so I have no personal interest in the CP-40’s preset sounds. Others may well feel differently and that’s fine.

    There is a good range of different piano sounds and it’s possible to tweak them a bit more to your personal preferences before storing the result as a preset. I like the fact that there are physical sliders for the 3-band eq so that it’s easy to make little adjustments to the sound during the gig.

    All in all, it’s a decent instrument that does a good job on the stage. I wouldn’t choose it for playing at home but it’s a very useful and practical gig piano.
