Upgrades for your Yamaha Disklavier! Where to Start?

This list is designed to help you understand the options for upgrades for your Yamaha Disklavier. It can be confusing, so start here!

No matter what model of Disklavier you have, it’s worth looking into some good sources of music! I also have a list of free MIDI sources to recommend. See my Disklavier compatibility table for an idea of what file formats your Disklavier can play.

Early Disklaviers (Mark I—III)

PianoStream App

One of my favorite simple upgrades for early Disklaviers is connecting them to PianoStream! PianoStream is a piano radio app designed to work with nearly every player piano, including the Yamaha Disklavier.

The app offers its own version of piano radio, providing you with a very large repertoire of high-quality music. It also allows you to stream MIDI files from your phone to your Disklavier, altogether bypassing the floppy drive.

Richie Hayes, the developer of PianoStream, also has an active PianoStream Facebook group where people can make requests.

Nalbantov Floppy Disk Emulator

Many customers choose to upgrade their old floppy disk drives with a Nalbantov floppy disk emulator. These devices altogether replace the original floppy disk drives. You can then store your entire inventory of floppy disks on a single USB stick!

See my article on backing up your floppy disks so you can play them on the Nalbantov. Additionally, you can order my floppy disk backup service if you’d prefer not to do it yourself! I can prepare them for your particular Disklavier, and for the Nalbantov. See also my favorite USB stick for the Nalbantov. I also have an interesting article on backing up your floppy disks using a Greaseweazle, if you have either an exceptionally large number of disks, or if they’re difficult to read using other tools.

If you’re installing a Nalbantov in the Yamaha MX100II, you’ll need a bracket. You can also order the bracket directly from me.

At this time, if you want to record with your Disklavier, the Nalbantov is a necessary upgrade. The PianoStream App does not currently support recording.

Replacement Power Supplies

Power supplies on this generation of Disklavier almost invariably fail. Fortunately, TAP Electronics rebuilds Disklavier power supplies. Simply ship them your power supply, and they’ll rebuild it and ship it back. They remain the only provider endorsed by Yamaha for this service. Last I checked, this was a flat rate of $750. The rebuilt power supplies do not have the defect the original did, and will last much longer.

Replacement LCD Screens

Is your LCD screen blank? It’s quite likely that the screen has died. You can attempt to repair it yourself by replacing the capacitors on the old screen; however, replacement screens are still available! They are Yamaha #VN635201. They can be purchased on Yamaha 24×7, and are available for less from SynthParts. The new LCD screens do not use the electrolytic capacitors prone to failure, and will last much longer.

DKC-850 Upgrade

The Yamaha DKC-850 can be installed as a “piggybacked” device on the earlier Disklaviers. This means that the DKC-850 is installed in addition to the original Disklavier, and connected through its MIDI jacks. This adds most features of modern Disklaviers, including Yamaha Piano Radio and conventional USB ports.

Mark IV

Wi-Fi, Internet, and Firmware

The most common question I get about Mark IV Disklaviers is how to connect them to the internet. Oftentimes, the owner is struggling to connect, even though they know their device is plugged directly in to a live internet connection. In that case, you need to update your Mark IV firmware. Out-of-date firmware will not talk properly to Yamaha servers! If you have any trouble updating on your own, you can order my firmware update kit.

DKC-900 Upgrade

The Mark IV can be upgraded with the Yamaha DKC-900. This enables you to use your phone or tablet to control the piano, and is aesthetically much subtler than the Mark IV.

Nalbantov Floppy Disk Emulator

Has your floppy disk drive stopped working? If you want to gain back that functionality, you can install a Nalbantov. On the Mark IV, this is much less useful than on previous Disklaviers, as most of your disks are already saved on the hard disk.

PianoStream

The PianoStream App does also work on the Mark IV. This is an alternative to Yamaha piano radio, and is less expensive. It also allows you to broadcast MIDI files to the piano from your phone or another device. Of course, with the Mark IV, you can already use USB sticks, so this isn’t as large an upgrade as it is on previous Disklaviers.

Solid State Hard Drives

Sometimes hard drives fail on the Mark IV. The Mark IV uses old spinning disk hard disks. If you notice them chattering or exceptionally slow performance, consider upgrading your Mark IV to use an SSD.

E3 / DKC-850

Wi-Fi, Internet, and Firmware

The most common question I get about E3 series Disklaviers is how to connect them to the internet. If you know you have your Disklavier plugged into a healthy internet connection, and it still won’t connect, it might be time to update your E3 / DKC-850 firmware.

DKC-900 Upgrade

The E3 can be upgraded with the Yamaha DKC-900. This enables you to use your phone or tablet to control the piano, and is aesthetically subtler.

PianoStream

The PianoStream App does also work on the E3, and you might be interested in this as an alternative to Yamaha Piano Radio.

Enspire / DKC-900

Wi-Fi and Internet

The Enspire and the DKC-900 represent major upgrades over previous generations of Disklavier; however, they are still surprisingly challenging to connect to the internet. See my article on a straightforward and effective way to connect your Disklavier to the internet.

PianoStream

The PianoStream App does also work on the Enspire, and you might be interested in this as an alternative to Yamaha Piano Radio.

Yamaha E3/DKC-800/DKC-850 Firmware Update

The Yamaha E3 / DKC-800 / DKC-850 firmware update is wonderfully simple, unlike its older Mark IV sibling. The entire update can be done using just a USB stick with at least 20 MB of memory.

The Problem: No Internet Connection, Despite Being Plugged In

In October 2020, Yamaha mandated that its pianos use better encryption standards (all pianos now use TLS 1.2 instead of TLS 1.1). If you connected your piano to the internet before October 2020, it probably automatically updated to the latest firmware. However, if you weren’t so lucky, you’ll have to perform the updates yourself.

The Solution: Updated E3 / DKC-800 / DKC-850 Firmware

First, you’ll need to download a copy of the new firmware, and you’ll need a USB stick.

You can obtain this from Yamaha’s Disklavier E3/DKC-850 Firmware Updater V3.54 page, after agreeing to their license agreement. Once you have the dkv_update.bin file, simply copy it on a USB stick (not in any directories or folders).

Take that USB stick and insert it into your Disklavier. Now hold down the Play / Pause button and power on the system (with the Play / Pause button still held). From there, you can follow the on-screen instructions.

If you have any difficulties, I’ve embedded a link to their instructions PDF below. You’ll need to start with “Downloading the Update Program using a PC and USB Flash Memory” on page three.

At this point, you should be able to sign in to your Yamaha Disklavier Radio account from the controller. Make sure this works! If you still can’t see the internet, then it’s worth reevaluating your network setup. See my article on connecting your Disklavier to your Wi-Fi!

Connecting your Yamaha Disklavier to the Internet

Yamaha Disklaviers are an innovative fusion of digital and acoustic engineering, but connecting your Disklavier to internet is somehow still very challenging! They allow you to experience famous, concert pianists performing right in your living room, on your piano. They’re an excellent tool for both entertainment and for learning. And of course, they’re just fun to watch. Take a look at this beautiful 2009 Yamaha GC1 Disklavier playing Billy Joel’s Piano Man that I recorded last summer.

If you have a previous generation of Disklavier and haven’t updated its firmware since October 2020, it is absolutely necessary to update it before attempting to connect to the internet. Your Disklavier will tell you it isn’t connected to the internet, regardless of what you do, until the firmware is updated. I have additional information on updating the firmware on the Disklavier E3 (DKC-800 / DKC-850). I can also help with updating the firmware on the Disklavier Mark IV, and can even provide you with the media.

They do have one drawback: Connecting your Disklavier to Wi-Fi networks can be confusing and difficult. Yamaha provides the UD-WL01 adapter, but this is not an intuitive device: Is your Disklavier acting as an access point for other devices, or are you connecting your Disklavier to Wi-Fi as a client? Is it doing both? Can you tell from the instructions what you’re expected to do, and how you’re supposed to use the Disklavier and connect to the internet at the same time?

I’m sharing an incredibly elegant, simple way to connect Yamaha Disklaviers to the internet. You don’t have to worry about reconnecting it if you change your Wi-Fi password or buy a new router. You can set it up quickly, and it works in most houses.

Supplies

A little redundant labeling makes all the difference. And Small-Caps adds some style.
A little redundant labeling makes all the difference. And Small-Caps adds some style.

1. NexusLink Powerline Ethernet Adapters

These devices allow you to network through the electrical lines in a house. Your piano will believe it has a physical connection, and you won’t need to do any further configuration!

These devices are effortless to use once they’re paired: All you have to do to keep your piano connected is plug them in!

Make certain that the adapters are plugged directly into outlets, or into the surge protector below. Power conditioners, universal power supplies, or even higher-end surge protectors interfere with their signal. Similarly, they must be plugged into circuits that are in the same breaker box. Multiple breaker boxes or sub-panels can interfere with the signal.

It’s worthwhile to label the adapters. This will help with troubleshooting in the future. If you have specific networking needs, you can download the full manual for the NexusLink Powerline adapters here.

2. GE Designer 3-Outlet Surge Protector

This is an 8-foot extension cord with a three port power strip on the end. It calls itself a surge protector, but doesn’t do any regulation or conditioning which might interfere with the NexusLink signal.

I did a tear-down of the device to make sure there were no surprises: Surge protection is achieved through a metal oxide varistor, and there is no voltage regulation beyond that.

3. Black CAT6 Ethernet Cables (3 feet)

With piano work, subtlety is a must. Anywhere black or concealed equipment can be used, I use it. Three foot cords have always been more than enough for me. In many installations, I’ll even use one-foot cords. More cord just means more to hide.

4. 3m Dual Lock Reclosable Fastener (or equivalent)

These are strong, interlocking fasteners that aren’t vulnerable to vibration, and are strong enough to hold up the end of the extension cord. I’ve also used very large (2′) zip ties wrapped around the beams underneath the piano, and these work well.

Installation and Connection

1. Prepare and Pair NexusLink Adapters Beforehand

Remove the two NexusLink Adapters from their box and plug them both into the outlets where you intend for them to go. One will be next to the router and, and the other will be plugged into the extension cord you intend to put underneath the piano. No Ethernet connections are necessary at this time.

If the green connection lights on your NexusLinks turn on (the top light on each adapter), that means they’ve found one another, and are now communicating through your household power. Great!

Now you can secure their connection to each other. On the bottom of each unit (near the Ethernet jack) there’s a small configuration button. Hold it down for three seconds, and the bottom of the three lights—labeled with a padlock—will begin to blink. Now press the same button on the other NexusLink for three seconds. After a short period of time, the padlock lights will turn solid. Then, some seconds later, the connection lights should turn solid as well.

These two NexusLinks are now a permanently bonded pair. No matter where you put them, they’ll find one another. In fact, they’re so tightly paired that they’ll even ignore other NexusLinks.

If you have specific networking needs, you can download a full manual for the NexusLink Powerline adapters here.

2. Run the extension cord up underneath the piano

With the Disklavier turned off, unplug the Disklavier.

Pick a good spot to mount the power strip underneath the piano. This is usually parallel to the floor on the side of one of the wooden beams adjacent to the Disklavier controller. (Also, make certain if there is a Dampp-Chaser installed, make sure the NexusLink isn’t near the humidistat, where the small amount of heat it produces might cause less accurate readings.)

Wipe the area down with alcohol. Take two pieces of your Scotch Interlocking Fastener and, after removing the backing, affix both to the back of the power strip. Mount the power strip to the beam.

If possible, try to route the power cord over a beam. This will keep it a more secure in the event it gets pulled on. You can even loop it around the beam once if you have enough cord.

3. Plug everything in

Plug your other NexusLink Powerline Ethernet Adapter into the bottom port of the three of your power strip. Run a short length of Ethernet cord to your Disklavier controller. If possible, loop the Ethernet cord up over the beam to apply a bit of tension. Pianos produce plenty of shaking and vibration, so keep things as secure as possible. Use no more cable than you need.

Now plug the Disklavier power into the power strip (and the Dampp-Chaser as well if one is installed). This extension cord is comfortably rated for the power consumption of all three devices.

At this time, both the green connection lights should be on, and both the padlock lights, meaning the NexusLink Adapters have discovered one another. If this isn’t the case, skip to the troubleshooting below.

Use zip-ties, twist ties, and other appropriate cable management to bundle everything up and out of sight. Stick-on conduit can be used to run cords along the beams if precise positioning is needed, such as if the piano is positioned next to a low couch or somewhere else people might easily see underneath. I’ll actually sit in various chairs in the room and look at the piano.

You’re all done! If it doesn’t work immediately, read on.

No connection! What went wrong?

First: It’s probably a power strip or Universal Power Supply (UPS)

Do not plug either Powerline adapter into a power strip or surge protector if you can avoid it. These often filter out the signal. Only simple power strips (like the GE one I recommend) will not block the signal. When in doubt, plug directly into the wall. And don’t forget to check the adapter that’s near your router. This also needs to be plugged directly into the wall.

Second: It might be the outlet

If the outlet isn’t receiving power, it won’t work. Make sure that the outlet can power other devices, and that it isn’t controlled by a switch.

Third: It might be the breaker boxes

If the house has multiple breaker boxes, then the devices might not be able to see each other. In this case, try different outlets. You can try changing outlets both near the piano and near the router.

Has it been working for a while, but suddenly stopped?

As with many other pieces of sensitive electronics, if it’s been behaving and suddenly stops, you should power cycle the devices. Unplug each Powerline adapter in turn and plug it back in. If that doesn’t work, pair the adapters again in the manner described in step one.

Other Options to Connect your Disklavier to Wi-Fi

If none of the available outlets work, you’ll need to try a different approach. This article is specifically on the Powerline adapter technique, but you’ll need to consider using a Wi-Fi bridge, since the Powerline adapters won’t work for you. These bridges are also an easy way to connect your Disklavier to Wi-Fi, but will require you to update your login information if your network changes.
