Upgrades for your Yamaha Disklavier! Where to Start?

by

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.

If you have an HQ100 Disklavier free this era, see my article on installing a Dampp-Chaser on the back of the HQ100.

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 Disklavier, MIDI, ESEQ, and Floppy Disk Tools

by

I use a wide variety of software tools when reading floppy disks and preparing ESEQ and MIDI for the Yamaha Disklavier. Below is my attempt to compile the most useful tools I use on a daily basis. If you have any input or want any further information, please don’t hesitate to contact me.

WinImage

A comprehensive disk-imaging suite for Windows. Notably, it successfully transfers Yamaha Electone Performance floppy disks when other tools see them as unformatted. Although it can read some Clavinova and Electone floppy disks, it can not read Disklavier floppy disks. Nonetheless, it’s a versatile floppy disk tool, and a worthwhile addition to your arsenal.

DKVUTILS (The OG Tools for the Yamaha Disklavier)

Available in DKVUTILS.ZIP on my drive. These are essential utilities for copying and managing Yamaha Disklavier floppy disks.

ESEQ Explorer
Facilitates the creation and management of PIANODIR.FIL for Yamaha Disklavier. Using ESEQ Explorer, you can create PIANODIR.FIL directories for your ESEQ files. This is necessary for older Disklaviers, and also allows you to modify song titles and metadata.

MIDI2SEQ
Convert standard MIDI files to ESEQ for early Yamaha Disklavier compatibility.

ESEQ2MID
Transform Yamaha Disklavier ESEQ files into standard MIDI format. This tool is extremely helpful if you’re transferring your songs from floppy disks from an older Disklavier, to a USB stick for a newer one!

MID2PianoCD

MID2PianoCD is a Windows utility by Mark Fontana for encoding MIDI and ESEQ files into player piano-compatible formats. It supports various electronic player piano systems, including Yamaha Disklavier, PianoDisc iQ, Live Performance LX, Marantz Pianocorder, and QRS Pianomation. You can use it to generates CDs that can be played directly on MIDI player pianos, expanding the versatility of your Disklavier’s music library.

Mark Fontana is an extremely knowledgeable and talented individual, and his software — both this and PPFBU below — are vital staples. He requests donations on his website, and if you find his tools useful, you should support him.

Player Piano Floppy Backup Utility

Player Piano Floppy Backup Utility (PPFBU) is the premier Windows-based tool for backing up Yamaha Disklavier and PianoDisc floppy disks. It’s an indispensable tool for backing up your old floppy disks. He requests donations on his website, and if you find his tools useful, you should support him. It has a user-friendly interface, and can be used with USB floppy disk drives, even when Windows cannot see or open the disk.

Website: www.kinura.net/ppfbu/

The “Official” Recommendation for the Yamaha Disklavier: Giebler’s Yamaha DOM Package

Giebler produced a utility with wide-ranging compatibility with Yamaha devices. It will read older Yamaha Clavinova disks, in addition to Disklavier disks. However, this software is old, requiring versions of Windows that mostly can’t even be installed outside virtual machines. If you’re interested in how to get this running, read my article on using Giebler to explore old Clavinova disks.

For nearly all purposes, I recommend PPFBU above, although in isolated circumstances this software might make more sense for your particular project. Yamaha still recommends them today.

All software runs under MS-DOS on IBM PC-XT, PC-AT, or compatibles with a hard disk drive and an internal (non-USB) 3 1/2” floppy disk drive. Most programs are also compatible with MS-DOS shells under Windows 3.1, 95, 98, or ME.

Keirf’s Greaseweazle

The Greaseweazle allows you to duplicate your Yamaha Disklavier floppy disks — or any other floppy disk — without Windows even necessarily being able to open it. Even better, the Greaseweazle can read your floppy disk as an .hfe file, which you can simply drop onto your Nalbantov USB emulator! It can be used in place of all the tools mentioned above.

The Greaseweazle captures raw flux transitions from drives, enabling the capture and analysis of any disk format, including those used by Disklaviers.

Website: https://github.com/keirf/greaseweazle/wiki

Keirf’s FlashFloppy used with a Gotek

FlashFloppy is a powerful firmware solution for Yamaha Disklavier floppy drive replacement and management. A Gotek floppy disk emulator with FlashFloppy installed, used in conjunction with the Greaseweazle, is the single most reliable method of reading floppy disks in USB stick format.

When paired with Greaseweazle, a Gotek with FlashFloppy becomes an exceptionally powerful tool for managing Yamaha Disklavier floppy disks. Greaseweazle captures raw flux transitions to create accurate disk images, which can then be easily written to or read from using FlashFloppy on your Disklavier.

FlashFloppy is open-source, and Keirf’s tools are incredibly valuable for our purposes transferring old floppies. The FlashFloppy firmware can be challenging to install on a Gotek for the first time, so purchase a Gotek with FlashFloppy already installed.

The alternative to FlashFloppy is HxC’s custom firmware which is paid/closed-source, but is used by Nalbantov below:

Nalbantov Floppy Disk Emulator

Nalbantov provides premium floppy disk emulators tailored for specific Yamaha Disklavier pianos, offering seamless integration and exceptional compatibility. The Nalbantov drive comes with guaranteed compatibility and is easy to use, and their support is excellent.

The Gotek and FlashFloppy solution described above will work as an inexpensive alternative; however, it can be a challenging DIY project, and is not advisable for anyone who isn’t quite comfortable tinkering with their own hardware. Additionally, Nalbantov manufactures slimmer drives that fit in models of Disklavier the Gotek does not.

They support a wide range of Yamaha Disklavier models, including early models (MX22, MX80, MX85, MX100A/B, MX116) and advanced models (MX500, Mark II/IIXG/III), as well as various Disklavier Control Units (DKC50R, DKW10, PPC3R, etc.).

For Disklavier owners seeking a reliable and easy-to-use floppy disk emulator with guaranteed compatibility across numerous models, Nalbantov is the best choice. You can search for your model of instrument on their website, and they will send you a properly configured device accompanied by a compatible USB-stick.

GN MIDI Professional

GNMIDI is a powerful tool designed for musicians, educators, and MIDI enthusiasts to play, edit, and convert MIDI files with ease. It’s very useful for converting MIDI files from Type 1 to Type 0. You’ll need this tool to prepare MIDI files you find on the internet for your Disklavier. The professional version allows you to perform large, batch operations, but the lite version works to convert files individually.

Reading and Writing Yamaha Disklavier Floppy Disks

See my article on Yamaha Disklavier Floppy Disks, ESEQ, and MIDI Formats for more information on how to use the above tools to extract songs from your disks.

See my article on Converting MIDI Files and Creating PIANODIR.FIL for ESEQ Files for more information on how to use the above tools to convert MIDI files and prepare ESEQ files for use in older Disklaviers.

Quality Public Domain MIDI Songs for your Disklavier

by

I’ve made a brief list here of websites where you can find free or public domain MIDI files. I always recommend registering or donating if you find the services valuable. If you’re downloading numerous songs at once, I highly recommend DownThemAll, a browser extension that allows you to simultaneously download many files at once. In most cases, these should be used for personal use.

Please also see my premium list of songs for your Disklavier. This list contains only inexpensive or readily available MIDI files, typically in the public domain.

Not sure whether you need MIDI or ESEQ? Check the Disklavier compatibility table. Remember if you’re using the Pianostream app, you can use MIDI files regardless of your Disklavier model.

Kuhmann Directory (the OG MIDI Source)

This directory was my first source for high-quality MIDI and ESEQ files, and was placed online by a Robert C. Kuhmann. Unfortunately, they’re now no longer online. You can access my complete scrape of the MIDI files here. Or my complete scrape of the ESEQ files here. You’re able to download these directories from me in their entirety. If you’re curious, this is the Wayback Machine archive of Robert Kuhmann’s website.

Kunstderfuge

This website has a very large inventory of music, and they’re probably my favorite resource. They advertise that they have 20,000+ songs to choose from (1,000+ composers, 400+ pages). These are MIDI files, so you’ll need to convert them to ESEQ for older Disklaviers if you’re not using a Pianostream. They convert nicely and are organized very well.

However, they do have a five song limit if you’re not a paying member. To become a paying member, a lifetime membership is $20.

mfiles

This website has another large inventory of files, and also offer to do music on commissions. If you’re looking for a specific song you can’t find anywhere, you might try contacting them.

Music commissions are “satisfied by composer Jim Paterson. We suggest clients check his Original Portfolio for examples of his music, and contact him direct via mfiles commissions with details.”

Website: https://www.mfiles.co.uk/

MusicMoz

This website has yet another large inventory of MIDI files, and a search tool.

“MusicMoz is a comprehensive directory of all things music, edited by volunteers. We list, and accept submissions of, music-related reviews, articles, factual information, biographies, and websites.

You can browse the site using our hierarchy of categories, or use the search feature to locate the information you’re looking for.”

Website: https://musicmoz.org/Sound_Files/MIDI/

Saarland Music Data

The Saarland Music Data (SMD) website provides a collection of synchronized MIDI and MP3 recordings performed on Yamaha Disklaviers by students from the Hochschule für Musik Saar. Although the site is no longer updated, you can still access and download these MIDI files. They are compatible with newer Disklavier models, can be played on older Disklaviers using Pianostream, or used with floppy disk emulators after converting to ESEQ.

As this appears to be an older University website, I’ve also mirrored the files here.

Other MIDI Sources

Have a particular song in mind? You might try using this useful bit of Google-fu. Search for your song replacing any spaces with plus signs, and include “filetype:mid” in your search. So, for instance, if you’re searching for “Hey Jude,” try Googling the following phrase:

hey+jude filetype:mid

If you’d like, I can do this for you. Just fill out the following little form below:
