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.

This is by far the best synth I have ever laid hands on. It does everything I could ever wish for from a single instrument including lush strings, pads and some nice SH-101 type mono synth sounds (using chord memory and portamento). Here's an all Alpha Juno-1 sound example:

The CR2032-T12 battery is soldered to the main board.

This is passable in chord mem mode (octaved not a chord) as a poor man's sh-101. It has a similar rubbery tone and waveform 3/mix similarity. Not much cop as a proper pad machine really, it sounds nice but it's very poor next to proper 2 DCO or 1 VCO synths. And of course it can't an SH-101 in reality, but if you can't afford a real 101 this can do a kind of weak/fake version. Though it won't fool anyone. And it only fakes it if you keep the resonance down, the res on the real 101 is amazing and the filter in the juno 1 or 2 is rather weak.

I have had this synthesizer for almost two years. At first I was disappointed that I did not manage to program good sounds. But after a while it went better and the breadth of sounds it can do! From pure "techno" sound to "Vangelis landscapes". I have previously owned include both Roland Juno 60 and 106 and the Yamaha CS 15 and CS 60, but this I am most pleased with. Fun to play, easy to program and cheap to buy!
