Behringer Pro-1

F
ollowing the release of
their own take on the
Model D, Behringer’s
Pro-1 is an all-analogue
tabletop synth that
takes inspiration from a
certain classic by Sequential
Circuits, the Pro-One.
Originally released in 1980,
the Pro-One was said to be
inspired by a single voice from the
iconic Prophet-5 synth, but it had
a few tricks of its own. Behringer
didn’t mess with the successful
formula too much, as their Pro-1
is an all-analogue monosynth that
features two oscillators, a beefy
filter with its own ASDR envelope,
a subtly complex modulation
matrix, and a simple sequencer/
arpeggiator. Looking at the
architecture of Behringer’s Pro-1,
you’ll see that not much has
changed from the synth that
inspired it. There are two
oscillators, the first of which offers
sawtooth and square waves, with a
variable pulse width of the square
wave. There’s a four-octave range
for each oscillator, as well as a
fine-tune knob for those slightly
detuned sounds. The second
oscillator also has sawtooth and
square waves, but adds a triangle
wave into the mix as well, which
adds a nice warm, subby flavour to
the Pro-1’s sound.
Pro tool?
Each waveform can be turned on
individually for each oscillator, so
there’s quite a bit of timbral
complexity available before the
signal even gets to the filter. Each
oscillator has its own level knob in
the mixer section, and there’s also
a separate white noise generator.
When an audio signal is plugged
into the external audio jack on the
front panel, that knob becomes a
volume for that source. Oscillator
1 can be synced to Oscillator 2 for
those classic tearing/ripping
sounds that you’d associate with
many classic ’80s synth riffs.
