Roland Alpha Juno-1

The Alpha Juno is a great sounding Juno type synth! Not quite as warm in sound as the previous Juno's but still a nice addition to any techno synth rig. 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. The PG-300 synthesizer programmer gives you traditional slider control of each parameter for much easier and faster editing.

Other nice touches include better MIDI implementation than previous Roland synths, 64 presets and 64 user 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 Alpha Juno 1 was soon replaced by the Alpha Juno 2 which added a few MIDI & keyboard enhancements. The MKS-50 is an upgraded rackmount version of the Alpha Juno. The Alpha Juno is used by Mundo Muzique, Vince Clarke, Matt Megaton Haines, Paul Hardcastle, Massive Attack, Bomb the Bass, The Prodigy, Youth, Joey Beltram and Human Resource.

The HS-10 Synth Plus 10 is an Alpha Juno for the casual home user, with a slightly less appealing cosmetic appearance, and the HS-80 was a similar repackaging of the Alpha Juno 2.

Great bass sounds, IMHO. Subjective, sure, but there are MUCH weaker analogues out there. AJs are harder to find nowadays, I had to drive for 2 hours to get one. Totally worth it. I miss velocity sens (Roland are STINGY), but I can live without it.

The alpha dial is fiddly but I was able to program the AJ1 effectively within half an hour. There aren't many parameters which helps. Only one LFO, and negative values aren't possible, but the osc sounds GREAT: sub osc can be set to various octaves! Classic chorus, clear at the top end, good filter.

It's not all that versatile but I love it!

Perhaps it's not as fat as some others, it's not as loud and aggressive, it's not that versatile, it's not that punchy and it's relatively ugly. But - it is all those things and - it has incredible character. It won't impress the cool crowd instantly because it doesn't do generic synths sounds well, nor can it be programed ad infinitum. But it has a deep, warm and haunting, even melancholy quality at its core that can't be replaced by any other beast. Its warm and soft strings beneath an acoustic guitar track almost disappear, but add great depth and warmth. That's just one example. 5/5

This was my first synth. While it can definitely do all of the signature Roland sounds I eventually found it too crisp and bright sounding for my tastes and moved on to a 106 which offers much more in the low end department. On the plus side it is very compact and lightweight. It can also make some complex evolving drone sounds that other previous Roland synths can't manage.

If we are only talking sounds the Juno 1 is a highly capable analog synth.
Tremendous for leads, bass, luxuriant strings and pads, brass and the like!
My chorus was a little noisy and of course the alpha dial can be tedious.
Not nearly as stylish or hands on as a 106 or 60... But again a super solid little
player that will fit into a mix extremely well in most all genres of music.
