Michael Bedesem was the creator of a group of terrific freeware utility programs called "The Style Manager Series" that supported Yamaha PSR and Tyros arranger keyboards. Michael is retired from programming now and support for several of his utilities is now provided by other programmers.

Four of Michael's remaining utilities (FolderCheck, MidiPlayer, & StyleDump are still available here on the PSR Tutorial. They provide users with additional capabilities for managing song, style, multipad and voice files and are designed to operate on a PC with the Windows™ Operating System (95 or later). Below is a brief description for each of these four utilities. Click on the links below or any of the links shown above for more details.

FolderCheck (Version 1.0.4 - July 22, '14) is a PC application to assist you in managing folders on Tyros models with hard drives. Yamaha instruments will refuse access to media folders that exceed limits (250 files per folder for Tyros 1 and 500 for Tyros 2/3/4/5). The program enables the user to examine the number of files per folder and split them as desired. It works on your PC, on a USB drive, or on your Yamaha hard drive connected to the PC via the MusicFinder button-initiated storage mode. FolderCheck replaced the earlier HDCheck program. Version 1.0.4 changes include a number of user requested enhancements as well as maintenance items.

MidiPlayer (Version 8.3.1 - Dec 16, '14) is used to play, convert, repair, normalize, display, and edit the song, style, multipad and voice files used in the keyboard. This program will translate files for operation on another instrument. For example, if you have a PSR-3000, you can use this program to convert Tyros style files for use on your PSR-3000. The program includes a "batch" facility so you can process many files at once.

StyleDump (Version 2.0.1 - Oct 3 '10) is multi-purpose file viewer that can be used to list, sort, search, copy, and print the contents of Yamaha style files, section data (Main A, Ending A, etc), CASM, OTS, MusicFinder database entries, Midi song files (type 0 & 1), Voice edit files, Organ flute files, and Multipads.
