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.

it stopped working, the keyboard will not boot up. the screen has a small line on the top left corner. when i power it on, the lights come on but nothing comes out of it. does anybody know what this could be?

A little note: "Brilliance" under "Tone Modify" on the Alpha Junos controls not only filter, but the PW/PWM. I noticed that when I decreased brilliance on a string patch and the PWM became more subdued making it a square pad.

I like how you can set the chorus speed instead of having it fixed at one or two (relatively fast and obvious) settings like the other Rolands.

The action is very comfortable to play. Glad I got this instead of the Alpha Juno 1, I heard its action doesn't feel so good, and at least for me the smaller size isn't much of a benefit.

Beside the design of the top panel, Im impressed by everything. Happened to find it on the local classified, & have taken it home today with less than $200 paid.

Better than many expect, the Alpha Juno's offer an all-round solid analog sound, which might not blow you away, but will certainly offer up plenty of warm-ish strings and pads, solid basses and softer leads, as well as some more out-there sounds. However, the membrane switches and lack of hands-on control takes away a lot of the fun, unless you get a good programmer like the PG-300 to go with it - but that lifts the price into range of maybe more desirable options. As such, this is a useful instrument which had (and has) a hard time fending off the competition. At least it's still cheap.
