Heiko Plate's program PSRUTI can be downloaded here. With this tool you can add Yamaha XF chords in a MIDI file. The chords are generated automatically. If you want to extract chords when you import a MIDI file in One Man Band's arranger window, then you will need this freeware tool. Normally XF chords are only present in MIDI files created with Yamaha arranger keyboards. But thanks to Heiko it is now easy to add them in any MIDI file.
