APS MIDI Prep Tool is a desktop utility for Windows and Linux built for Yamaha Disklavier and legacy player-piano workflows.
It combines tasks that previously required several older utilities into a single modern application.
Features include:
- Reading and backing up Yamaha PianoSoft disks
- Recovering files from aging floppy media
- MIDI Type 1 to Type 0 conversion
- Yamaha E-SEQ conversion and extraction
- PIANODIR.FIL generation and repair
- Song-title and filename cleanup
- FAT12 and floppy-image workflows
- Preparing media for Nalbantov and Gotek floppy emulators
APS NoteCast is an Android MIDI playback and recording application designed around wireless MIDI hardware such as CME WIDI devices.
It provides a practical way to play MIDI files through compatible digital pianos and Disklavier systems without relying on older computers, floppy disks, or dedicated playback hardware.
The project includes support for playlists, Bluetooth MIDI connections, background playback, MIDI recording, and workflows built around large MIDI libraries.
Additional projects provide focused browser-based tools for common MIDI and Disklavier problems, including file conversion, pedal-data processing, Yamaha XF cleanup, and legacy disk-image preparation.
Many are published as free utilities through alexanderpeppe.com.
Older Disklavier and player-piano systems often rely on obsolete media, Yamaha-specific formats, unusual MIDI conventions, and software that is difficult to run on modern computers.
These projects are intended to make those workflows safer, clearer, and easier to preserve.
Most are developed in response to actual instruments, files, and compatibility problems encountered in service work.
These projects are intended for lawful repair, preservation, interoperability, and personal-use workflows.
Use them only with disks, recordings, and files that you own or are authorized to preserve, convert, or modify. They are not intended for unauthorized distribution of copyrighted music, commercial player-piano libraries, proprietary software, or other protected material.
