Piano service, web development, and software tools for Yamaha Disklavier and legacy music technology workflows.
Alex's Piano Service LLC is a piano service company based in Maine, specializing in acoustic piano service, digital piano repair, Yamaha Disklavier systems, MIDI workflows, floppy disk preservation, and practical tools for older player-piano systems.
This GitHub organization hosts software projects related to:
- Yamaha Disklavier file preparation
- MIDI and E-SEQ conversion
- PIANODIR.FIL generation and repair
- Yamaha PianoSoft floppy disk reading
- Nalbantov, Gotek, HFE, IMG, and Greaseweazle workflows
- WordPress tools used on alexanderpeppe.com
- Web-based utilities for musicians, technicians, and player-piano owners
APS MIDI Prep Tool is a desktop utility for Windows and Linux that helps prepare Yamaha Disklavier and player-piano files. It can read Yamaha floppy disks, convert between MIDI and Yamaha E-SEQ, edit displayed song titles, shorten filenames for older systems, convert MIDI Type 1 files to Type 0, and work with floppy image workflows.
It is designed to replace a collection of older, fragile, and confusing utilities with a single modern tool built around real service workflows.
Typical uses include:
- Backing up Yamaha PianoSoft floppy disks
- Recovering readable files from aging disks
- Converting E-SEQ files to standard MIDI
- Preparing MIDI files for older Disklaviers
- Creating or refreshing PIANODIR.FIL
- Editing song titles shown on Disklavier and player-piano displays
- Preparing files for Nalbantov and Gotek floppy emulators
These projects support online and server-side floppy image workflows, including conversion between legacy disk image formats and more accessible archive formats. Some tools are designed for integration with WordPress pages on alexanderpeppe.com.
The goal of these projects is to make difficult legacy music-technology workflows safer, clearer, and more accessible.
Older Disklavier and player-piano systems often depend on older formats and Yamaha-specific file structures. These details are easy to get wrong, and mistakes can make disks or files appear unreadable.
These tools are built to reduce that friction.
These projects are intended for lawful preservation, repair, compatibility, and personal-use workflows.
Use these tools only with disks and files that you own or are authorized to preserve, convert, or modify. Do not use them to distribute copyrighted music, commercial player-piano libraries, proprietary software, or other material you do not have the right to share.
