I’ve been developing software to assist player piano and, in particular, Yamaha Disklavier owners with common problems. I independently develop all my software, and it’s currently in its early development phase. If you have any notes, please don’t hesitate to contact me and report bugs or request features.

APS MIDI Title Editor

APS MIDI Title Editor is a simple yet powerful tool designed to change the title of the first track in a MIDI file. This allows for clearer and more organized song names. It’s especially useful for Yamaha Disklavier owners want their songs properly displayed on the instrument’s screen.

This makes it easier to navigate and play back performances. With a quick and intuitive process, users can load a MIDI file, modify its track title, and save the changes.

APS Shortener

APS Shortener is helps you rename music files so they are compatible with early Yamaha Disklaviers. Early player systems can only read short filenames (DOS 8.3). Simply drag and drop your files into the program, and it will automatically create shortened copies while keeping the originals untouched.

Application for Changing MIDI Titles

by

I built a simple Windows tool to help you with changing MIDI titles. I’ve seen countless Disklaviers display blank or gibberish titles for their songs, and that makes finding the right song quite difficult. I’ve had several customers ask me if there’s a program that does this easily, and the answer until now has been, surprisingly, no!

Features

Drag-and-Drop Simplicity
Just drag your MIDI files into the program. It displays each file’s current filename and track title, so you can make quick edits right there in a clean table.

Easy Title Editing
Update the internal “track_name” within your MIDI files with just a few clicks. This ensures your Disklavier shows the correct title.

Why This Matters

Yamaha Disklaviers combine classic piano craftsmanship with modern digital technology. But with that blend comes the need for precision—even in your file names. A well-organized MIDI library means less time fumbling through files and more time enjoying your music. This app is all about making that process as straightforward as possible.

It notices when filenames are too long for earlier Disklaviers.
