Easily one of the most common questions we get here at Merriam Pianos from digital piano shoppers is how long do digital pianos last? And that’s really not surprising since this is going to be a top question among consumers when shopping for just about anything, whether on Amazon or in a store.
Like with most consumer goods, digital pianos exist in a range of quality levels and as a result, there’s not a one size fits all answer to the question of how long digital pianos last.
In this article and companion video, we’ll cover which components and areas of a digital piano are most likely to fail over time, and provide a quick summary of the expected longevity and durability of digital pianos across different price points and quality levels.
This should prove quite useful if you’re shopping for a digital piano and can certainly weigh in on your decision-making process depending on what kind of lifespan you’re looking to get out of your instrument.
How Long Do Digital Pianos Last? - Background & Context
This article and video really wouldn’t have had much relevance 10 or so years ago. The reason for this is that only a very small percentage of the buying population back then would've been looking at a digital piano as a long-term purchase.
Professionals like arrangers and performers, of course, would be concerned about how long a given digital piano would last for obvious reasons, and a few hobbyist players too undoubtedly. The difference today is that there’s a much larger segment of the buying population focusing on a digital piano as the last type of piano that they will ever own.
This shift has occurred for a number of reasons. For one, the sound quality of even an entry-level digital piano is pretty darn good these days and totally eclipses the piano sound of expensive digital pianos from not too long ago. Apps have come a long way to the point of being a legit selling feature too.
There are also a number of playing situations as a homeowner where an acoustic piano simply isn't practical, especially with such good quality digital options that provide home-friendly flexibility.
Digital Pianos Don’t Last Forever
How long digital pianos last is a more pertinent question today than it ever has been at any point in the history of the instrument. But digital pianos do not last forever, and they are not infinitely repairable either.
Regardless of whether you're buying an entry-level instrument or a really high-end instrument, your digital piano at some point is simply not going to function the way it was when you first bought it. You will eventually get to a point where it can't be repaired anymore. A good rule of thumb is the more expensive the instrument, the longer the lifespan in pretty much every case, though how the digital piano is used is a huge factor.
Acoustic pianos are an overall different case. Acoustic pianos are forever repairable, and while you may get to a point where the economics are no longer justifiable, that doesn't mean that it's not possible. With many digital pianos, you will actually get to the point where you simply can't source a replacement motherboard anymore.
Which Parts Fail?
Piano Action
At the top of the list as to which components are most likely to fail on a digital piano is definitely the key action. Actions fail or at least degrade for the most obvious of reasons - the mechanism gets pummeled over and over again. In a single playing session, for example, you could be pressing a piano key thousands of times.
Multiply this by weeks, months, and years, and you've got a mechanical point on the instrument that is simply enduring a ton of repeated force.
On upright pianos and grand pianos, the same principle applies, with acoustic instruments requiring regular maintenance of the hammer actions (of course they need tuning too), especially with consistent use.
Motherboard & Other Digital Electronic Components
The next major fail point on a digital keyboard tends to be its motherboard or circuit board, as well as other digital electronic components such as key sensors. When the motherboard or sensors will fail is fairly unpredictable, but we do find that these can fail with minimal use, but overall this tends to occur at a very low percentage.
Most manufacturers will have some type of fail rate on their electronics within a range of about 0.5% up to 2% or so. When it does happen, there's really nothing to be done other than replacing the failed components. As long as you are able to get in touch with the manufacturer within a reasonable amount of time after buying the instrument, odds are you'll be able to get the motherboard replaced whether it’s still under warranty or not (many digital pianos come with a 1-year warranty).
After a particular model has been discontinued, there should still be spare parts kicking around for a period of time, but once those are no longer to be found, the instrument will be essentially kaput.
Key sensors are subject to quite a bit of impact, but while most of the impact on a key is cushioned by other points, key sensors are another component that do sometimes fail, whether they stop working or start misfiring and are unable to detect the correct touch sensitivity. Individual sensors often can be replaced, especially in higher-level actions, but in older models eventually, new sensors or sensor strips may not be available. Keep these above points in mind when considering a used piano.
Broken Input/Output Jacks
The third common fail point is actually totally preventable, but we see it all the time - busted input and output jacks. Most digital pianos these days are going to have a number of terminals, such as headphone jacks, sustain pedal jacks, MIDI jacks, USB jacks plus of course a jack for your power source, and these need to be treated with some care.
What happens quite frequently is that a jack will break or loosen up and fall into the instrument. In other cases, the actual electronic connections will break which means that the jack will need to be re-soldered, but in some cases, this can be difficult to accomplish.
This can happen quite often in homes with young kids, so just keep in mind that headphones need to be plugged in and unplugged with care.
Speakers & Amplifiers
Speakers are always going to be a wear component, but they tend to last a very long time. In fact, speakers themselves are likely to be one of the longest-lasting parts of any digital piano. They're not a particularly complex component, and as long as the speaker hasn't been overdriven, you can find speakers that are decades old, even relatively low-quality ones let alone high-quality speakers.
If you are constantly maxing out the amplifier or leaving it on for extended periods of time, the odds increase that it might blow. If you’re pushing your digital piano in the 90%-100% of its possible volume range all the time, there is going to be a very high chance that the amplifier simply won’t make it to the end of its intended lifespan.
Digital Piano Lifespans
The ranges here are going to be fairly wide since the amount of use a digital piano receives is going to be the biggest factor in how long it will last. For example, a basic entry-level electronic keyboard or synthesizer that is rarely used but taken care of could last substantially longer than a higher-end stage piano like a Nord (though they are very durable) subjected to the abuse of a touring musician.
That said, being a major volume piano retailer that also happens to have a major music education department has allowed us to observe pretty strong trends in this regard and form a reliable guideline as to what you can expect under normal home use conditions.
We’ll also list some good models from each category, most of which you’ll be able to in-depth reviews on over at our YouTube channel.
Entry-Level Digital Pianos
Entry-level piano keyboards tend to last anywhere from about 3 to 7 years on average. This is more than enough time to get some interest in piano playing and perhaps even trade up to a better instrument while your keyboard still has lots of life left in it.
Mid-range digital pianos tend to be solid anywhere from about 5 to 10 years generally speaking. Of course, many musical instruments from this category tend to wind up inside practice rooms at University music departments, and those ones are going to require replacement much faster due to heavy use by aspiring pianists.
The very best digital pianos currently available, many of which would be referred to as hybrid instruments with the same actions as their acoustic counterparts, high-end speaker systems, cutting-edge sound samples and powerful polyphony will generally offer users 10 to 15 years of trouble-free use.
Some great options in this category include the KawaiCA and NOVUS series instruments, RolandGP and LX series pianos, the Casio GP series and Yamaha Avant-Grand series.
Closing Thoughts
We hope this overview of digital piano longevity has been useful. As we said, this has really been aimed at the general user, so if you’re a professional or have some hyper-specific use case in mind, get in touch with us directly for a more specific estimation of longevity.
In this article, we're going to be taking a look at Yamaha's P515, the flagship of Yamaha's P series. We'll be looking at the action, the sound engine and obviously talking about the rest of its features and what other instruments you could be looking at in parallel to the Yamaha if you are on a search for a portable instrument in that $1,500 to $2,000 price range.
Yamaha P515 Digital Piano Review Video Transcription
Sound Engine:
We'll start by discussing the sound. The P515 happens to be equipped with a pretty advanced tone engine, with 256 maximum note polyphony. For people out there who aren't too sure what polyphony is or why it's potentially important, a given digital piano's polyphony count represents the maximum number of individual tones that this can sort of simultaneously play at one time. We have detailed video on our YouTube channel explaining polyphony in more depth if you're interested. 256 note polyphony means you could technically hold the damper pedal down, sweep all the way up and down the piano voices three times before the processor starts dropping notes. Under any normal playing circumstance, 256 notes polyphony is plenty and has become the standard for higher quality instruments, starting around the $2,000 price point and going and up from there.
In terms of the sound engine itself, the main acoustic piano samples Yamaha has used here is their Yamaha CFX concert grand piano as well as the Bosendorfer Imperial concert, both 9 ft concert grands. Yamaha refers to their sampling process as Binaural Sampling, which is then enhanced by Stereophonic Optimizer technology for headphone use. These samples sound quite distinct from one another with the CFX sample bring quite colorful, bright and very dynamic, whereas the Bosendorfer Imperial piano sample is a darker natural sound with a more compressed dynamic experience. There's of course some other acoustic piano samples as well making up a pretty good variety of tones to choose from. Overall, the acoustic piano sample here offers an all around authentic piano playing experience, especially with the CFX and Bosendorfer Imperial piano samples.
There's this function called Piano Room, which operates very similar to what like the Roland's Piano Designer, Kawai's Virtual Technician apps. The piano room app allows for intelligent acoustic control of some of the finer nuances of piano tone. For example, some of the parameters you can edit are lid position height, the brightness of the hammer, touch response curve, reverb depth, metronome, master tuning, damper resonance, string resonance, virtual resonance modeling(VRM), and aliquot resonance. As you can guess, that allows the user a lot of control to customize the piano tone, which is something that's essentially becoming a standard feature on most digial pianos at this price point. It's nice to see that Yamaha is also doing a really nice job with this here. I enjoy the graphic nature of the user interface here, as some instruments leave it up to shortcut command and you can't really visualize what's happening, so having the display makes the whole process more intuitive.
The onboard speakers are rated at 40 watts in total. There's 15 watts per side for the main and then it also lists two 5-watt tweeters. The main speaker is basically a two-way speaker system with a main speaker inside the cone. Embedded on top is an additional tweeter and they rate those separately. 40 watts is enough to fill a small room, and certainly enough that you don't need an amplifier to enjoy private playing. It's probably not enough to gig with, but likely fine for lighter rehearsals.
Other sound categories here include the standard E piano stuff, including a nice Phaser EP. There's also a patch that sounds like a Wurlitzer, as well as a "Disney" patch, labeled DX. Once you get into the clav, the vibes and the strings patches there's a little bit of hit and miss in how well these sound come across, but the acoustic piano and E. piano tones are definitely very well executed. The Yamaha tone is quite specific - a totally different experience than playing, for example, a Kawai which tends to be a little thicker in terms of the tone and maybe a little warmer. Roland's generally have wide selection of sounds and once you get to the FP-90, there's sound modeling which is a totally different experience. Some people really like that, and others don't. For people who are a fan of the Yamaha style of tone, I think they've done a really great job and the piano should work in a variety musical genres.
That's basically a wrap up of the discussion of the tone engine, and a quick review of the types of sounds that are included on-board, and a few other thoughts as well.
Piano Action:
Let's talk about the action on this P515. There are things about the action that I like, and then there are things about the action that I would say is important that you be aware of it. I'm not going to necessarily categorize these aspects as positive or negative, but rather a buyer beware. We'll go through these observations one by one.
The action Yamaha has put into the P515 is what they call the NWX(Natural Wood X) action. This action is a wooden key/plastic key hybrid and both visually as well as in a tactile sense gives you a smooth release and greater feel of an acoustic grand piano. Many digital pianos in this price range offer a featured referred to as escapement or let-off. Escapement is the sensation on a key that is caused by the jack slipping off the knuckle on a grand piano. Basically, you've set the hammer in motion, it swings up, hits the string, without being physically connected to anything so it can bounce back freely, and reset the action. On a real piano this sensation is readily apparent, and within the last 5 to 10 years, digital piano manufacturers have started including that sensation in the portable design of their keyboards to make it feel a little bit more like an acoustic grand piano. I was always puzzled by this because I always thought that this sensation was an unintended sensation on an acoustic piano, to begin with. In any case, it does make you feel more familiar when you're in front of digital technology if you've got some experience playing an acoustic piano.
While Yamaha advertises that the P515 has escapement, I actually double-check that with the specs because after I first played one, I didn't really feel the escapement sensation at all. For people who are looking for a keyboard where that escapement is a little more prominent in terms of the sensation it gives you, this action may fall short of the mark. For people who don't like the feel anyway, just ignore the specs and carry on.
The key surface on the white keys is basically a polished white plastic. This is a very different approach than what most high-end digital pianos have taken within the last few years, which is to go with with a pretty porous white surface to give a greater sense of texture. In the case of Roland or Casio, they've actually gone with a full ivory keytops texture, so Yamaha's choice here is a little bit unusual. The drawback with a polished key surface is that they tend to be quite grippy anytime you're in a more humid environment which can make it a bit more difficult to play intricate music that requires precision of finger position. Otherwise, it's just a personal choice that's neither good nor bad, just something to be aware of.
The black keys on the other hand have a very grooved, deep texture. The feeling is similar to that of a new Mason & Hamlin acoustic piano from the last 10 years or so, for anyone whose had a chance to play one. It sort of feels like an unfinished ebony wood type of texture. Again, this quite a bit different than what you get on most digital pianos, and it's something that some folks will love, and others will not. The NWX uses a triple sensor which means you're going to have very accurate MIDI output, which is great.
Coming to the last subject and probably the one that needs to be addressed most directly is the weight of the keys. Before I'd played the P515, I'd been on a number of forums to read about other people's impressions, and the weight of the keys is a topic of discussion quite often, as several people had made the comment that the keys were heavy. I come from an acoustic piano world originally, and an acoustic piano should have a key weight (meaning the amount of weight that it takes to put the key in motion) anywhere from about mid-40s at the very lowest up to about 60 grams at the very heaviest. Most concert technicians usually try and weigh the key depending on whether it's at the bottom of the piano or the top of the piano, anywhere from the low to high 50 grams. These keys on the P515 are considerably heavier than that. In that respect, it's consistent with some of the larger Yamaha stage pianos of the past like the CP300. I played one of those for years in a pit band and it had really heavy keys as well. This is something that Yamaha's user community may be used to and appreciate, but for somebody who's not used to it, playing on this instrument for an extended period of time is somewhat fatiguing. I'm someone who's used to playing multiple gigs per week and having those gigs be three to four hours long, so my playing muscles are well conditioned and I find this action tiring.
I hope this isn't coming across as necessarily a negative, as some may love it and It may be exactly what you're looking for. For people who are looking for a strong sense sense of depth to the key, perhaps this action exactly what you're looking for. But it's something to be aware of that the keys are in the 70-gram range, heavier than a grand piano action.
Features/Accessories/Connectivity:
The Yamaha P515 is comes standard with a few extra accessories, and offers some optional add-on's as well. With wooden accents and polished details, the P-515 looks as good as it sounds. This is consistent with what you generally find in the market from your major manufacturers. Good comparisons to the P515 would be the Roland FP-60 or FP-90, as well the Kawai ES8. The first thing that's included with the P515 is a very solid sustain pedal unit (FC4A). I really like the inclusion of a robust sustain pedal, and it's really frusterating when digital pianos come with those little plastic square pedals that just skid all over the place. This pedal is much more stable and it offers the ability to perform half-pedaling.
The P515 also comes with an integrated music rest, as well as a standard PA-300C power supply. In terms of optional add-on's, you've got available a matching keyboard stand for the keyboard itself, which compliments the furniture and makes the instrument look a little bit more like a stationary piano. There's a triple pedal system that you can be added on as well, and the inclusion of both the stand and triple pedal essentially turns the P515 into a home digital piano.
In terms of connectivity on the back of the instrument, the P515 features an independent 1/4-inch aux outs and aux in, a mini-jack audio input and a Bluetooth radio for quick connection to an iPad or other device. I have to give kudos to Yamaha in terms of how easy it is to turn on and off the Bluetooth audio function. On many digital pianos this feature can be somewhat hidden and require a look at the manual to switch on, so the ease of use of the feature here is most welcome.
Last but not least, there's USB connection that heads out to the computer that also acts as a USB audio connector. This mean the Yamaha P515 is going to work really well if you've got some external software instruments that you're using, such as Ableton, with the P515 functioning as a MIDI controller. There's no need for any of this external mixing as it all goes in and out through the USB connector, so this is super handy. On the front of the P515, we've got a USB device port. This is for things like audio recording, so you can plug that in and you can record WAV straight to here - another super useful feature.
When it comes to features, the P515 has all the standard kinds of digital piano features that you would expect. There's transpose, split, dual mode, sound boost, and EQ. Navigating all of the features is very easy via the user interface. One last function I'm going to highlight here is the rhythm function with onboard accompaniment. There's a lot of control here, and this function would work great for fun at home or light professional applications.
Yamaha has also made available the Smart Pianist app for iOS, which creates a remote control touch screen interface, super cool. The Smart Pianist app also has the ability to access the songs in your iOS device's music library and create chord charts to make for easy play along with your favorite songs.
Conclusions:
This pretty much wraps up our review of the Yamaha 515 - an instrument that is definitely focused on delivering a high quality, authentic piano experience. I'm very impressed with the acoustic piano sounds, the E piano sounds and how easy it is to use the piano editing module. Be aware that this is a heavier action featured here, and somebody who isn't accustomed to that or isn't expecting that this might feel a bit of buyer's remorse if they purchase the instrument before trying it. Otherwise, this is a capable instrument and certainly anyone who is in the market for a high-end all-in-one portable digital piano, should have this instrument on your wish list to check out, along with the Roland FP60, FP90 and Kawai ES8. Thanks for reading!
