Welcome to the APS Software Wiki, your resource for software tools developed by Alexander Peppe to assist Yamaha Disklavier owners, player piano enthusiasts, and musicians managing MIDI files and digital piano systems.
This software is designed to solve common problems faced by Disklavier users and other player piano owners—especially when it comes to managing MIDI files, file naming limitations, and ensuring smooth playback on vintage and modern systems.
With a background in both piano repair and software development, Alexander Peppe created these tools to simplify the digital side of player piano ownership. This wiki provides detailed information, support, and downloads for each APS tool.
