Recommended For: Classic big, punchy, analog
Oberheim sound. Excels at
everything a vintage poly synth
does, but with a broader tonal
palette and greater reliability. Fat
tone, ease of use, built-in effects,
and portability make it a natural
for on stage. Equally well suited
to studio work due to its superb
sound and ability to sit well in a
mix. Sets the standard for modern
analog poly synths.
1 sustain, 2 expression 1 sustain, 1 volume,
A sound designer and performer’s
polyphonic dream synth. Super
versatile, it has the depth of a
modular but is faster and easier to
use. Crystal-clear tone is great for
complex pads, effects, and evolving textures, but handles classic
synth sounds equally well. Nearly
endless sonic possibilities.

Classic thick, warm, analog
sound. Great for vintage synth
tones and more through its exible modulation matrix. Two-part
sound stacking and splitting
adds variety and exibility. A
solid analog poly performer in
the studio or on stage.
Like the Prophet 12, a sound
designer’s dream that performs
as either a mono synth or a
4-voice paraphonic synth. It has
the depth of a modular and the
CV connectivity to interface with
one. Sophisticated multitrack
sequencer ties into mod matrix
and adds vast possibilities.
Massive sound is well-suited to
leads, basses, effects, complex
evolving textures, and more.
Nearly endless sonic possibilities.
Like a 4-voice, 4-part multitimbral
Prophet ‘08 with additions such
as 2 sub oscs and a feedback
loop per voice. Same classic
warm, analog sound as Prophet
‘08. Great for vintage synth tones
and more through its exible
modulation matrix. Four-part
multitimbral operation adds great
exibility. A solid analog poly
performer in the studio or on
stage. 4-part multitimbral operation makes it great for sequencing
multiple parts.
All-analog mono synth. Classic
fat sound. Great for vintage synth
tones and more through its exible modulation matrix. Compact
and affordable but has a big,
powerful sound. Maximum bang
for the buck.
All-analog mono synth. Same
sound engine as Mopho but with
a 32-note keyboard. Classic fat
sound. Great for vintage synth
tones and more through its exible modulation matrix. Compact
and affordable but has a big,
powerful sound. Maximum bang
for the buck.
All-analog mono synth. Same
sound engine as Mopho but with
a 44-key keyboard. Classic fat
sound. Great for vintage synth
tones and more through its exible modulation matrix. Compact
and affordable but has a big,
powerful sound. Maximum bang
for the buck.
All-analog, 4-voice poly synth.
Same sound engine as Mopho
and Mopho SE. Classic fat analog
sound. Great for vintage tones
and more. Flexible modulation
matrix. A compact and versatile
performer in the studio or on
stage.
Monstrously powerful analog/digital
hybrid mono synth with true stereo
lters and ampliers. Has both analog
warmth and digital grit. Digital waveshapes from the Prophet VS, distortion,
tuned feedback, and bit crushing can
create edgy, aggresive textures unlike
any other synth. A sound designer’s
dream with a truly massive sound that
can go from smooth to threatening with
the turn of a knob.
