Each book in the MIDI Play-Along series comes with a 3.5 inch MIDI disk of complete professional performances, and includes matching custom arrangements in the E-Z Play Today format.
With this book, you can:

• Listen to performances of each song
• Play the E-Z arrangements along with the performances and sound like a pro playing with a real band!
• Remove the melody and play the lead
• Sing along with the full performances
• Alter tempo to perform at your own pace
• Play the arrangements on their own without the disk

The disk works with any General MIDI keyboard, regardless of the brand.
