This is an article about backing up your Disklavier Floppy Disks using a specific tool called a Greaseweazle. If you do not have a Greaseweazle, and want a straightforward and less technical solution, please see the article on backing up your Yamaha floppy disks using simply an external floppy disk drive and downloadable tools. I … Read more
The Yamaha Disklavier is a sophisticated piece of technology, but typically, you’re limited to Yamaha’s song library. Many Yamaha songs include both a piano part for the Disklavier and an accompanying music track, though the Disklavier piano part might differ dramatically from the original piano part in the song. In many cases, the piano tracks … Read more
I’ve recently installed some external speakers for various Yamaha Disklaviers. Hopefully my experience with this helps somebody else! The Yamaha Disklavier Mark IV is a well-loved, sophisticated instrument. However, upgrading its control unit to the DKC-900 offers several benefits—most notably, access to Yamaha’s Enspire radio stations and On-Demand radio. This is one of my recommend … Read more
Yamaha sold Smart PianoSoft floppy disks for Yamaha Marks III and IV. This was a revolutionary technology: You could insert a floppy disk designed to play the actual acoustic piano alongside an audio CD. In other words, the piano would accompany your CD! Yamaha released many such albums, and because the piano is accompanying the … Read more
This article on Mark IV Disklavier SSD Conversion was originally contributed by Richard Zajac. The Mark IV utilized a spinning hard disk, which was more than sufficient for the technology of its time. Even advanced systems like the Yamaha Disklavier don’t demand exceptionally fast read speeds, as piano notes aren’t played within microseconds of each … Read more
This Python program will recursively rename all ESEQ (.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. I’ve recently put … Read more
I recently installed a Nalbantov floppy disk emulator 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 … Read more
I have a customer who recently experienced an issue with his Yamaha Disklavier HQ100. The HQ100 is the Japanese version of the MX100II. He primarily uses this instrument over MIDI, and finds the Disklavier quite useful. This discussion should apply to other models of Yamaha Disklavier. Although the solenoids and part numbers differ between models, … Read more
I’ve had a couple of people reach out over the years looking for the bracket that supports the Yamaha DKC-850, otherwise known as the “hanger assembly.” The part number for this is, according to Yamaha, WT79210. Unfortunately, it’s been discontinued. However, you can use the hanger assembly for the Yamaha DKC-800, which is a perfect … Read more
Yamaha’s earlier floppy disks use the propriety ESEQ format. They also use a primitive form of copy protection, where the first sectors of the disks are missing. This means computers identify the disks as corrupt, requiring you to use specialized software to back up your Disklavier disks. In place of these sectors, Yamaha uses the … Read more
