If you have already read the
history of the Roland MKS50 elsewhere on the site, there's not much
to say about the Roland Alpha Juno 2.
It followed on the tradition of the Juno series by offering
a single DCO (digitally controlled oscillator) into a filter into
an output amplifier with a simple LFO and envelope for control duties.
Across the outputs was a chorus unit to beef the sound up.
However, the single oscillator could generate several
octaves at once and had a rich and powerful PWM that could be used
to fatten the sound quite considerably. Of course, it also had the
crisp and punchy filters that the Junos were favoured for and that
chorus unit helped give the thing a real richness that even some
true two oscillator synths had trouble competing with!
The Alpha Juno 2 was (not surprisingly!) the successor
to the Alpha Juno 1 but simply added an extra octave to the velocity
sensitive keyboard - nothing else significant was added to the synth's
