Roland Alpha Juno 2

This is an upgraded version of the Alpha Juno 1. It adds an extended 61 note keyboard with velocity and aftertouch and an external memory cartridge slot. Other than that it has the same great sound and features as the Juno 1. Sliders and buttons were replaced by membrane buttons and the Alpha Dial which is used to edit and browse through the extensive selection of parameters: DCO digitally controlled oscillators, LFO, bend, ENV, pulse, waveforms, noise, PW/PWM, high pass filter, VCF (filter) with freq/env/res/lfo/kybd, VCA envelope, chorus, and more.

Adequate in the studio or on the stage, the Juno 2 has 64 presets and 64 user memory patches, a nice LCD display, an LFO capable of a very slow rate for some cool sweeping effects, and a great bass sound (especially nice for acid basslines) and noise effects! It also has chord memory which is perfect for rave & techno, portamento and keyboard transposing. The PG-300 Synthesizer Programmer gives you traditional slider control of each parameter for much easier and faster editing.

The HS-80 is an Alpha Juno 2 for the casual home user, with a slightly less appealing cosmetic appearance. The Alpha Junos have been used by Mundo Muzique, Vince Clarke, Matt Megaton Haines, Paul Hardcastle, Fatboy Slim, Massive Attack, Bomb the Bass, The Prodigy, Faithless, Youth, Joey Beltram and Human Resource.

And I'm not the only one who thinks that, who KNOWS that, check the attack magazine top ten under-rated. THere is Juno 2 and number 2 and for good reason. This thing through some effects is so potent, I've not seen many other synths in this price range that can turn their hand to every kind of sound so well, best leads, great bass, amazing sweeps, brilliant pads, nice perc, great fx and even does a mean E piano or two. The PWM and Chorus are sublime and so pretty sounding too.

Right let's get this straight. Alpha Juno 2 is one hell of a good synth. Don't matter how limited it may appear, or how toyish it may seem from the interface - with a breakout programmer (even a generic sysx box) this thing rocks. It is so flexible, always sounds good, and is way more interesting than the early, simpler Junos. Sounds every, and I mean EVERY bit as good in the mix (you know actual songs that count) as the Juno 60 etc, but does things they can't. It's keyboard is superb quality and it has exactly the right features for the price! TOTALLY UNDER-RATED!! One of my top 3 under $1000

I have owned the Juno 6 the Juno 1 two MKS-50's and a 106. I just picked up a Juno 2 after selling all my synths a while back in favor of VST's , I now use the Juno 2 to control my VST's and for its wonderful analog , The alpha series IMHO are the best analog Juno's that were made. Alot of people call them hybrid analog digital synths which is totaly incorrect the Osc's are analog but digitaly controlled & stablized. Unlike synths like the ESQ1 SQ80 and DW8000 to name a few which use low bit samples and multiple waveforms for the OSC's. You cant go wrong with a Alpha Juno.!

Oh and definitely get this over the Alpha 1 if you plan to control software/rack synths with it as this outputs (and uses) velocity and aftertouch. The Juno 1 doesn't! The only juno to ever have this good a keybed (in feel) and keybed features (as above) - for me the best Juno, and it sounds great. I'm not a fan of the 106 at all, too simple.

Great things can come in small packages! This thing is compact and very handy as a desktop controller synth for software due to this, furthermore it sounds great on it's own too. Definitely analog but with a more refined sheen than older synths. The multi wave oscillators are fairly unique sounding too. You can connect this to any generic midi control box for full hands on programming. Good for bass, leads and some pads. Used by many top acts for it's sound even without the hands on sliders of the older junos.
