FP-50: How to play songs from a USB flash drive

The Roland FP-50 digital keyboard comes with tons of built-in songs; however, you can also load your own music onto a USB flash drive (up to 32 GB, sold separately), and play it through the FP-50 speakers.

The FP-50 can read both standard MIDI files, and audio WAV files (44.1 kHz, 16-bit linear).  

Here's how to do it:

1. Plug your USB flash drive into a computer, and load your favorite music.
2. Unplug your USB from the computer, and plug it into the piano (the USB port is located on the back panel of the piano, on the right side).
   
3. Press the [SONG] button.
   
4. While holding down the [SONG] button, use the [-] and [+] buttons to select the USB flash drive category, indicated by an "S" on the left side of the screen.
   
5. Once you have selected the "S" category, use the [-] and [+] buttons to select your desired song within that folder.
6. Press the [>/■] (Play/Stop) button to begin playback of that song.
