HP508: How to play songs from a USB flash drive

The HP508 comes with hundreds of built-in songs; however, you can also load your own music onto a USB flash drive, and play it through the HP508 speakers.

The HP508 can read both standard MIDI files, and audio WAV files.  

Here's how to do it:

1. Plug your USB flash drive into a computer, and load your favorite music (in Standard MIDI file form, or WAV file form).
2. Unplug your USB from the computer, and plug it into the piano (the USB port is located underneath the far right side of the keyboard).
3. Press the [Song] button.
4. While holding down the [Song] button, use the [-] and [+] buttons to select the category that says "USB".
5. Use the [-] and [+] buttons to select your desired song.
6. Press the Play/Stop button to begin playback of that song
