Analog Synthesizers / Keyboard / Roland / Under £500 / Vintage

Roland Alpha Juno 1 Analog Synthesizer

The Alpha Juno is a slightly cut down version of the Roland MKS 50/MKS-50. It still sounds fab but unlike the MKS50 it’s a keyboard version with membrane buttons and a small LCD display. It really benefits from having an external controller to get under the hood of the exterior to program your own patches the casing is heavy and well built. You can get a Roland PG-300 external controller to do just this or the Kiwi Technics PE (Patch Editor) which can be purchased new here on their website if you are finding it hard to find a used PG-300.

It has 1 DCO per voice, pitch bend, LFO, Sub, pulse, sawtooth, noise a sub oscillator to form your patches. Pulse width, portamento the classic chord memory for old-school rave and techno sounding riffs, and a chorus effect thrown in for good measure.

This model has a successor in the form of the Roland Alpha Juno 2, the newer model added MIDI and keyboard improvements over the Juno 1.

It has been used in the past by acts such as The Prodigy, Massive Attack, Vince Clarke, Human Resource (the dominator/hoover sound early rave music)!! And many more…

 

 

FINAL WORD:

Solid vintage analog synth sounds, but you could get a Roland MKS-50 Rackmount unit which will save you space and adds better features read here for more info.
