Roland Juno-Di

Roland Juno-Di Image

The Juno-Di is an updated version of the Juno-D that brings it more up to par with the Juno-G and Juno-Stage models. Roland has doubled the polyphony from 64 to 128 voices and packed in over 1,000 sounds thanks to twice as much waveform ROM (64 MB). They even gave it the same paint-job as the other Juno models. All this was done while retaining its original role as a good, cheap, portable entry-level synthesizer. Think of it as a Juno-G without the sequencer / audio-recording / workstation features.

The Juno-Di's 1,000+ sounds should be enough, right out of the box, to get any musician—entry-level or otherwise—going. They include grand and electric pianos, strings, guitars, brass, percussion, exotic instruments, modern synth sounds, and much more, including GM2-compatible sounds. Patches are organized into categories such as Piano, Guitar/Bass, Orchestra, Synth, etc. and are selected via dedicated category buttons located below the LCD display. The large scroll dial lets you quickly browse through all the patches within each instrument category.

The front panel is designed to be as simple and stream-lined as possible, offering only what is needed to quickly access, set up and play with its sounds. Five dedicated "Sound Modify" knobs provide access to basic parameters to tweak, including Envelope Attack, Release, Filter Cutoff, Resonance and Reverb amount. For all other sound editing you might want to do, a Mac/PC editor is included. From the computer you will have much more advanced access to its four tone generators, the TVF digital resonant filters, two LFOs (assignable to the pitch, filter, panning and level simultaneously), multi-effects, and many more Patch and Performance operations and parameters.

What really sets the Juno-Di apart from its bigger siblings is its lack of workstation features, most notably, the omitted sequencer and audio recorder. It does have an arpeggiator with lots of preset patterns, but you can't create your own, and it has some preset drum rhythm patterns, but you can't create your own. There's also phrase sampling and chord memory.

The Juno-Di is really a giant sound-bank of Roland's latest sounds with a 61-note velocity keyboard attached. Although it may not be a studio workstation, its portability features such as its light weight and ability to run on batteries make it ideal for traveling musicians. Additional features like Roland's D-Beam controller and a built-in vocoder with a mic input (and its own dedicated reverb) make it ideal for live performances. In addition, the "Song Player" can play SMF, AIFF, WAV, and MP3 files from a USB stick, that you can then jam along with like a real one-person band.

The Juno-Di is nothing like the original analog Juno poly-synths, except maybe for the look of the paint job. But it does offer Roland's latest technologies in their most portable and entry-level package. It really is a good general purpose keyboard for gigging but can also be good for advanced players looking for a cheap, quick and easy to use synth for lots of bread-and-butter sounds.

I have recently bought this synthesizer, also gigged with it. Sounds good on stage and off stage too. Havn't really been in a studio with it, but am sure would sound good in there too. The synth section is killer, expected greater diversity in the orchestra section, the given tones are good. It is a smart catch in this price. Encapsulating everything, happy to own a Juni Di... \m/

@broznik: Grimes used a Roland Juno-G for recording her albums, not the Juno-Di nor this Juno-Gi, which are newer ¨versions¨of the Juno-G, she uses a Roland GAIA now.
The Juno-di doesn´t even have a sequencer or sampler, and you can´t record audio on it...
so anyone interested in recording with a keyboard should not consider the Juno-Di for that purpose, i´ve read it`s used for singing along or live use, for performers :)

For anyone interested in hearing the capabilities of this budget Roland keyboard, have a listen to anything by Canadian artist Grimes - she's made two albums with one of these, a Roland SP-404 loop sampler and some multieffects! However I'm not about to start relying on preset keyboards, I enjoy programming too much :)

I bought one for its portability: 4 hrs battery life is OK, and I carry a spare set of batteries and a mains/car charger, along with the power adapter, a footswitch and a double x-stand, all in a gig bag. Travels easily. Typical Roland sounds, but way too many similar presets, and the piano samples are basic, perhaps due to the smallish wave ROM. Rhythms and arpeggiator are just basic fluff. Vocoder is fun. Mod knobs are useful, but its real strength is 128 note polyphony and the comprehensive PC editor. Well made, cheap and cheerful.
