Portable synthesizer includes Song Player lets you travel light, but play heavy.

The portable JUNO-Di is a traveling musician's dream. It's lightweight, can run on batteries, is easy to use, and yet it performs and sounds like a heavyweight synth. It's packed with a wide variety of over 1,000 top-quality sounds. The JUNO-Di also has a friendly "direct access" control panel for easy editing and a Song Player for larger-than-life performances. Whether you're a first-timer or old-timer, you'll love this friendly, portable, great-sounding synth.

Over 1,000 Great Sounds
At the heart of the JUNO-Di is a top-of-the-line voice engine that delivers world-class sounds - including grand and electric pianos, lush strings, beautiful guitars, powerful brass, percussion, plus banks of exotic instruments, modern synth sounds, and much more. The soundbank is so diverse, it can compliment any style of music you enjoy playing. And, if you want to customize the sounds, the dedicated "Sound Modify" knobs on the front panel let you instantly cater each sound to your specifications, even while you're playing. A software editor is also provided if you prefer more advanced editing via PC.

Simple Navigation
With so many sounds onboard, you might think it would be a daunting task to find what you need. But fear not - the JUNO-Di simplifies the process of finding sounds with its dedicated category buttons. If you want a piano, for example, just press the Piano button. You can even assign your most-used sounds to the Favorite buttons for instant access.

Editing is easy too. If you want to create layers or splits, dedicated buttons and the large LCD make the process fast and friendly. And, don't forget the onboard rhythm patterns, which can be easily adjusted on the fly with a dedicated tempo control. It's a great tool for practice and performance.

Born To Travel
The JUNO-Di is strong, yet amazingly lightweight (only 5.2kg) making it easy to lift and carry. The battery compatibility lets you play for up to five hours without plugging in (uses Ni-MH AA-size rechargeable batteries, sold separately). When used in conjunction with a battery-powered amp such as Roland's famous CUBE Street or MOBILE CUBE, the JUNO-Di can be played and heard anywhere. A battery-life indicator on the front panel ensures that you won't lose power unexpectedly.

Singing Along, Optional, Possible
The JUNO-Di lets you plug a microphone into its external input and process your voice through the built-in vocoder. A dedicated reverb is assigned to the input, so you can add lush ambience to your voice without taking away from the main onboard effects. Sing along with your performances and transform your voice in colorful and creative ways, from silky smooth to a more sci-fi robotic sound.

Built-In Song Player
With its USB MEMORY port and Song Player function, the JUNO-Di enables direct playback and control of backing tracks from a USB key. You can play MP3, WAV, AIFF, and SMF files, and control them from the dedicated buttons on the front panel. Impress your audiences with full-band performances from a single keyboard. Additionally, the Center Cancel feature lets you sing along karaoke-style with audio files in the Song Player for a complete entertainment experience. You can also connect MP3 players directly to the JUNO-Di through its external input.

Comments about Roland JUNO-Di Mobile Synthesizer White:

I bought this keyboard specifically for gigging. It's ease of use and programmability, along with it's solid selection of standard sounds make it a winner. The ability to make it truly portable via battery power and it's very light weight were unexpected bonuses.

My only wish would be for more sound variety, especially a more realistic Wurlitzer sound. Otherwise, worth every penny.

    Comments about Roland JUNO-Di Mobile Synthesizer White:

    When i plug this board into my pa or one of my big fender amps, it will rock your world. I think the best feature in the onboard mic imput. You can play and sing with an amp with only one imput. The mic has it's own reverb and vol controles Most boards are gray or black.
    Want something different and cool looking, get the white. I love mine, it's a keeper.
