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.

Does anyone know why the PWM on the sawtooth oscillator was never copied by any other synth? It sounds really different from PWM on a pulse oscillator, and it can make some real good and very original sounds (of which the "Hoover" sound is only but one example).

Apart from a few software synths no one ever made SAW PWM possible again. Not even Roland themselves. Or do I forget some synth?

I'm an original owner of the HS-80 version. Bought in 1987, I believe, when I was in high school. Fat sounds. Best pad synth I ever owned. Was great for the prog-rock group I was in. Rush-esq. Still have it but half of the keys lost their touch sensitivity. Recently the lithium battery died so all of the user memory is gone.
It has the ability to record patches for storage onto a cassette tape. Does know if there is somewhere you can download patches in that audio format?

Really like the sound of this synth, very underrated machine indeed.
Is there anyone out there that can explain how to save patch patches within the synth itself? Is "write" the only thing need to be done?

This is a massive and lush sounding analog synth. A bit of a dark horse really. Nothing much to look at, but the sound is where it's at. Programming is easy and the are plenty of free software editors which make it really fun.

It may only have 1 DCO but there are 14 waveforms + sub + pwm + chorus. I can get Oberheim strings and thick Moog basses out of this beauty, plus of course those squelchy Roland basses too.

Roland = Analog = Heaven

Simple!

This synth's architecture is a little bit limiting, but it does sound great. I really like the sound of the DCO and the filters.

Unison Mode on the Juno Alpha 2 turns this synth into a monster mono-synth.
I don't know whether or not the HS-80 is capable of the same.
To enter Unison Mode hold OCT Down and Function while powering on.

Currently I have both an HS-80 and Juno 2 linked running at the same time a couple of Hertz detuned. It is thick, analog magic. If you can pick one (or two) of these synths up I highly recommend them.
