Customers often ask where they can get songs for their Nalbantov-equipped Disklavier. If you’ve explored the other pages on my website, you know I’ve managed to cobble together a very large inventory of public domain music. For those using Nalbantov drives in older Disklaviers, I’ve preassembled a 108 disk selection, formatted using the ESEQ format compatible with those older systems.
This Java program will recursively rename .fil files in the specified directory, ensuring they follow the naming convention described, and convert all filenames to uppercase. If, for instance, you have twenty albums, direct this program to run in their parent directory, and all the albums in subdirectories will be corrected.
This script renames all files to be all-caps, and to have names exactly eight characters long. It will add filler characters if necessary. It will make sure they’re unique by incrementing a counter. These appear to be the most important factors in making files identifiable to early Disklaviers, based on my experience and those of commenters.
At this point, you’re ready to use EEXPLORE.EXE to move through each directory and prepare your PIANODIR.FIL. At a future date, I’d like to automate this.
Make certain to back up all files before running this! I can’t guarantee perfect results for all combinations of names and strings of characters.
Windows (EXE): Download and extract RenameForDisklavier.zip. Double-click on RenameForDisklavier.exe, and then select the folder containing all of your extracted albums. It will rename all the .fil files in all the subdirectories.
After you run RenameForDisklavier, you’ll see this box. Select the folder containing all of your .fil files, and it will do the rest.The renamed .fil files, demonstrating proper length, numbering, and capitalization.
I recently installed a Nalbantov USB drive using an updated version of the insert and mount that I designed.
You can see based on the pictures below that the Nalbantov slim is slightly too small to fill the entire cavity left by the original floppy disk drive. Additionally, there are no mounts of any kind to hold the Nalbantov in place. This insert solves both problems: The drive screws into the insert at just the right distance and depth, and the insert also buffers the area around the outside of the drive.
The insert installed over the screw positions of the original floppy disk drive.I 3D printed the spacers at 50% infill so they’d be fairly solid. These spacers allow you to use the original machine screws that hold down the OEM floppy disk drive, which is a huge advantage. No visits to the hardware store!
While installing and using Nalbantov drives in grand Disklaviers, I’ve encountered a recurring problem. The full-size USB sticks protrude too far, and are easily damaged by pianists or passerby.
This hardly protrudes at all. Without the cord, it’s difficult to even tell that anything is plugged in.
Below, you can see a USB stick the was struck laterally by a pianist. The solder joint snapped right off! That is an in convenience easily avoided by a good quality, low profile USB stick.
I’ve recently started recommending customers with worn-out floppy disk drives upgrade them to so-called “Floppy Disk Emulators.” There are a couple of these on the market, but it looks like the easiest to use and most reliable is the Nalbantov USB Floppy Disk Emulator. I use these regularly in Yamaha Disklaviers, but they can also be installed in keyboards. I install these quite regularly. If you do order from Nalbantov directly, make sure to use the AlexPiano for a 5% discount on orders from Nalbantov.
Why Upgrade?
There are several reasons why you might want to replace an old floppy disk drive with a USB floppy disk emulator, including:
Increased reliability: USB floppy disk emulators are more reliable than traditional floppy disk drives, as they have no moving parts and are less susceptible to mechanical failure. Most customers reach out to me after their floppy disk drive has failed.
Compatibility: USB floppy disk emulators are compatible with modern computers, which may not have floppy disk drives built-in or may no longer support floppy disks.
Speed: USB floppy disk emulators transfer data faster than traditional floppy disk drives, making it easier and quicker to transfer large amounts of data.
Convenience: USB floppy disk emulators can be easily connected and disconnected, making it easier to transfer data between different computers or to store data.
Cost-effectiveness: USB floppy disk emulators are often more cost-effective than purchasing a new floppy disk drive or repairing an old one.
I’ve found some floppy disk drives now cost more than the replacement USB emulators, especially if they’ve had minimal use. And hardly anybody knows how to actually repair a floppy drive—that’s a nearly lost art.
Operation
After the Nalbantov is installed, you can use a single USB stick to represent up to 1000 floppy disks. Because it’s a floppy disk emulator, the Disklavier actually believes you’re inserting a different floppy disk. As you switch between virtual “disks” by pressing the arrows, you’ll see the display on the Disklavier behave as though you’ve inserted a new disk. Of course, if you have more than 1000 floppy disks, you can invest in another USB stick, although I haven’t run into this particular situation yet!
The USB stick that comes with the Nalbantov is a standard, full-size USB stick. This protrudes rather far, and I’ve now run into multiple circumstances where the drive has been damaged by an incautious pianist. See my post on the Best USB Stick for Nalbantovs. Hint: It’s the SanDisk Ultra Fit.
This is the #2 track on the #27 floppy disk stored on that USB stick!
Installation
Some customers opt to install the Nalbantov unit themselves. Depending on the design, this is quite doable, although I don’t recommend attempting it with most Yamaha MX100II Disklaviers (see below). It is a very easy installation on, for instance, the DKC5R and the DKC500RW, just to pick a couple.
With some generations of Disklavier (most notably Mark II / MX100II / MX100A / MX100B devices), the floppy disk drives are mounted behind a shaped plastic piece. In these cases, you’ll need to cut away the old plastic facing (a pair of flush-cut nippers is helpful here), install the new drive, and put some kind of buffer around it. I’ve experimented with a few different choices for something functional and attractive. Purchasing neoprene strips is a cheap solution.
New solution: I have a 3D model of a floppy bezel that’s sized to fit around a Nalbantov. You can 3D print this yourself, or I can mail you one. This mount holds the Nalbantov in place, and also fills in the gaps around the edges. It’s an all-in-one solution for mounting the Nalbantov, and allows you to reuse the same screws the original floppy disk drive was installed with.
My solution/old solution: My previous 3D model in STL format of a floppy bezel simply filled in the gap around the Nalbantov, but didn’t help with mounting. You can 3D print this yourself, or I can mail you one. I adhere it to the replacement Nalbantov with a bit of hot glue, and then slide the whole assembly in. However, you’ll need to improvise a way to actually mount the floppy drive. I use mounting assemblies from old Yamaha slim floppy drives, but these appear to now be discontinued.
For backing up your current Disklavier floppy disks to a format that can be stored on your USB stick, see my article on Backing up Disklavier Floppy Disks. They can then be moved onto a virtual “disk” with Nalbantov’s proprietary tool.
