Using the E-A7 as a Song Player
Here we explain how to play back songs in the SMF, WAV, or MP3
formats supported by the E-A7.
Preparing to Use the E-A7 as a Song Player
When shipped from the factory, the E-A7 does not contain songs.
You’ll need to copy songs from your computer or other source.
1. Using your computer, copy the songs to a USB ash
drive (sold separately).
NOTE
Use a USB ash drive sold by Roland. Operation is not guaranteed
if any other USB ash drive is used.
2. Connect the USB ash drive to the E-A7.
NOTE
Carefully insert the USB ash drives all the way in—until it is
rmly in place.
