Midi with Lesson enabled

[Tian]

I noticed the optional midi songs provided by Yamaha, when loaded on a USB, can trigger the Lesson Feature on the Yamaha keyboard. But any other midi from the internet just plays the Midi and does not allow the Lesson feature. I'm just curious what parameters I should enable on the my midi to use it with the Lesson feature. I tried editing the notes on a DAW and Midi compositing software, but I was unable to trigger the Lesson on the Yamaha E473 keyboard.

You need to convert your midi files to midi format SMF0, for instance with the Yamaha File Utility:
