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.

What The . . .?
The one and only Hoover machine, responsible for one of the most (over)used sounds in electronica.
Many will say that it isn't as warm as a 60 or 106, but the Alpha has its own unique sound, which makes it a relevant addition to any studio.
You can find used models for next-to-nothing ($150-$200), so, if you're in need of a little "What The . . .?" Hoover in your mix, why not skip the samples and emulation and get the real thing?

the alpha juno 1 and 2 ( i own a 2) are hands downs some of the BEST synths ever made by roland! the presets are even killer but when you start programming and using sysex to sequence with the alpha juno, that's when the REAL fun begins!

Mmmmh.... I think there are some mistakes...
The Juno-2 doesn't have 3 DCO per voice but one DCO with several simultaneous waveforms...
And the envelope is not an ADSR (like the previous models) :
T1 / L2-T2 / L3-T3 / T4 is more powerfull than a 'standard' ADSR...

I recently got an Alpha 2 off of craigslist and absolutely love it. It is so much more fun and musical than I expected. The rich analog sound, responsiveness, etc.., is so much better from a true hardware analog synth like this. Highly recommended.

Wow "il", that's not true!
The Alpha Junos are one the most underrated synths out there!

JX vs. Juno = apples & oranges really..

Most people think this synth is totally Digital because it looks that way and doesn't have the typical wooden ends and knobs :)

It was the fad of the times; futuristic membrane buttons and little LCD's!

It's awesome, I love mine to the max!
