"This innovative portable piano unrolls to reveal a 49-key, four-octave electronic keyboard that sounds amazingly like a real piano. Its integrated keypad with digital display provides myriad options and inspirations for the aspiring or experienced player.

You choose from 100 realistic instrument tones — including piano, saxophone, harp and guitar — with a selectable "sustained notes" function. The rhythm accompaniment includes 100 different patterns in 13 musical styles, from rumba and rock 'n' roll to disco and country.

Have fun creating your own original music using recording and playback capabilities. Need a demo? Play 'n' Roll has 10 popular songs built in. The speaker is built into the keypad, along with a volume control dial. For big sound, connect Play 'n' Roll to a stereo amplifier or a home theater sound system via the auxiliary output jack. Input jack lets you play privately with your own headphones.

The entire piano rolls up into its own drawstring pouch. Plug it into any outlet with the included AC adapter; or for portability, it also runs on 4 AA batteries (order separately). Measures 10 1/2" x 2" x 2" and weighs 2 lbs".
