Onstage or in the streets, the Roland JUNO-Di keyboard is a traveling musician's dream. It's lightweight, it can run on batteries, and it's easy to use, yet it performs and sounds like a heavyweight synthesizer. The synth is packed with a wide variety of over 1,000 top-quality sounds to choose from. It has a friendly direct-access control panel for easy editing and a Song Player for larger-than-life performances. First-timers and pros alike will love this friendly, portable, wonderful-sounding Roland keyboard.

Over 1,000 great sounds
At the heart of this exciting new synth 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, banks of exotic instruments, modern synth sounds, and much more. The sound-bank is so diverse it can complement any style of music. If you want to customize the sounds, the JUNO-Di keyboard's 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 audio editing with your PC.

Simple navigation
With so many sounds onboard, it could be a daunting task to find what you need. But fear not-the Roland 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. This Roland synth is a great tool for practice and performance.

The JUNO-Di was born to travel. It's strong yet amazingly lightweight (under 12 pounds), 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). When used in conjunction with a battery-powered amp such as Roland's 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.

Sing along
More than meets the eye, this Roland keyboard 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 sci-fi robotic.

Built-in Song Player
With the synth's 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 Roland JUNO-Di through its external input.

    Pretty good for the price....

    By solerman

    from Zion, IL

    Comments about Roland JUNO-Di Synthesizer Keyboard:

    The Roland Di is a great little keyboard. I am very impressed with the piano sounds. I love some of the pad sounds too. If you are looking for good synth sounds, you will find them here. Very light weight keyboard. The construction feels a little cheap although it seems durable. Overall I gave it a 5 because of the great sound engine and ease of use. I primarily use it in my studio.

    Very Professional Roland Keyboard for a not so Professional Price

    By solitudedude

    from Diamondhead Mississippi

    Comments about Roland JUNO-Di Synthesizer Keyboard:

    Simply put, this Keyboard with its very impressive feature package, flexibility and conveniences if made just a few short years ago would have cost several thousand dollars easily. This is the first synth I've ever owned that has more than 1,000 sound patches, 1,300 to be precise and it's got the most fantastic line up of very professional sounds, and musical cultural multiple genre and thematic friendly expressions on many levels of its functionality as well. This synth with its 1300 sounds, midi controller, D BEAM volume control usable while in play, voice sing along, and voice recorder, 127 favorites saving user presets allowing you to save favorites in a very convenient all add up to making you the best musician, performer, entertainer, or sound engineer you can be for the money. This is a synthesizer that also has a cd that you can use to edit sounds from the board, and store them in your computer and play them via the midi controller like a several thousands of dollars synth, and it has a usb data back up disk to back up any and all settings you utilize within anywhere in the board. This is too good a deal to pass up and I mean its even made very well. Being made out of high quality plastics, its plenty tough enough to where if you take care of it it will return the favor. Just a note, but many a very old Hammond B3 organs had keyboards mad of much cheaper and thinner plastic than this is and they have lasted for numerous, like 4 or 5 or 6, decades. This board could last some of you the rest of your playing life. Great board for the price, there is really nothing else out there for the same price anywhere!!!!

    2.0 disappoint me

    By David

    from Milwaukee, WI

    Comments about Roland JUNO-Di Synthesizer Keyboard:

    I bought this workstation a month ago and gave it a solid chance considering i've never owned a roland synth before. After having it for two weeks i realized that most of the sounds can't really be tweaked and honestly sound like one shot samples especially in the synth category. The arppegiator is stiff and doesn't work well with most of the sounds very well and all the arp presets are just as boring as the sounds. Its also a horrible midi controller and didn't work well with anything but reason. I also found the editor software to be very poorly made. Lastly its not very good for playing live with either, it doesn't even save your settings so i had to go in and change tempos and everything in between songs. This workstation has almost ruined my faith in roland completely.

    Midi Controller

    By William Mcknight

    from Nashville,TN

    Comments about Roland JUNO-Di Synthesizer Keyboard:

    Ok I know all the things you have heard about this board great sounds, mobility, battery powered and a lot of other cool things, but to me the best thing is I can use it as a midi controller. along with all of it's chord functions arp functions and yes even the D-Beam (don't put it in midi control mode if you are using reason to use the D-Beam), and yes for those of us that like the joystick style mod and pitch control you can use that too. So along with all of the other things this board can do it is a great midi controller. I use it in conjunction with my Akai MPD32 and it is a great rig when you combine it with the power of Record and Reason from propellerhead. Heads up for you producer's out there my beat sells have gone up since I purchased this board. P.S. If you are wondering why it did not get 5 stars it's because I thought the piano sounds were weak, I have better ones in my Reason Rig.

    Give me my old 106 back

    By Allen Halstead

    from Chatham, NY

    Comments about Roland JUNO-Di Synthesizer Keyboard:

    After living with this keyboard for 16 months I think I know it pretty well. It's ok but nothing that all these 5 star ratings say it is. I find the piano sounds weak, the organ parts not much better and the string sounds are scratchy ... In order to make major changes to a sound you need to spend hours on a computer figuring it out ... guess I am old fashioned but it was a lot easier in the old days to make changes to the sound. In essence, you get what you pay for ... if you are a keyboard player doing a lot of gigging, this will not be your main piece.

    Roland is what I choose

    By Peter Sheehan

    from Phoenix, Arizona

    Comments about Roland JUNO-Di Synthesizer Keyboard:

    I've been using Roland Synthesizers for 30 + years, from the Roland SH-1000, the GR-500 guitar Synth, to the Juno-6, and now the Juno-Di. The Roland JUNO-Di Synthesizer Keyboard is a excellent addition to any bands instrument inventory. Whether on the road or in the studio the Juno-Di Synth does it with style. I recommend this keyboard to anyone who wants to become a better musician.

      Comments about Roland JUNO-Di Synthesizer Keyboard:

      I just got a great deal on a used DI from GC. The paint scheme looks like a 3p or 106. There are plenty of sounds to find a few you like, and they are easily modified. Pianos, organs, strings and even the synth sounds are excellent. Splits, dual and stacking are great and easy to use, performance mode is great too. I use the mic in as a guitar line in, which can add reverb, so the DI is like a little mixer. At 1/2 the price of a new DS this is a great Juno, with the right monitors or amp the sounds are very very close in quality. Icing on the cake is the Di weight like 10 lbs and runs on batteries !
