Analog Synthesizer with Dual VCOs, 3 Simultaneous Waveforms, 4-Pole VCF, Extensive Modulation Matrix, 16-Voice Poly Chain and Eurorack Format

An ultra-affordable homage to the iconic Pro-One synthesizer of the 80's, with all the features of the original and then some, the PRO-1 lets you conjure up virtually any sound with incredible finesse and ease. With its pure analog signal path, dual authentic VCOs with 3 selectable waveforms, plus extremely flexible VCF and VCA filters, the PRO-1 is sure to become one of your favourite keyboards. Owning the PRO-1 is like having your own personal time machine, enabling you to embrace the past or make your imprint on the future!

Versatile VCF
The very heart of PRO-1's sound is its classic 4-pole filter, which lets you freely experiment with the Cutoff Frequency, Resonance and Envelope and Keyboard amount, and full complement of ADSR (Attack, Decay, Sustain, Release) controls to dial in the perfect sound. PRO-1's filter Mode switch can be set to either Lo- or Hi-pass for selecting the range of your choice.

Authentic 3340 Oscillator
PRO-1's 3340 Voltage Controlled Oscillators (VCOs) provides your choice of up to 3 simultaneous waveforms (Oscillator A: Sawtooth and Pulse, Oscillator B: Sawtooth, Triangle and Pulse), with a selectable range of 4 octaves. The VCOs can be modulated via the envelope or the low frequency oscillator (LFO). Performance is further enhanced by the Mixer section, which balances the levels of the internal VCOs and noise generator. This amazing flexibility gives you the tools to be your creative best.

Eurorack Ready
Designed to handle the rigors of life on the road or in the studio, your PRO-1 can easily be transferred into a standard Eurorack case for the perfect integration into your existing system.

Product ExperienceI own it
Closest StoreBedford, Nova Scotia
I owned an original Pro-One for almost 25 years, until selling it a couple years ago. And so it was great to get those sounds back in my studio! I love this little reproduction; I paired it with a Keystep controller, and not only does it sound amazing, it's now actually fun to play (the originals have awful actions, clunky and uneven). I prefer the Behringer Pro-1 over the Model D for wild fx, created on the matrix on the left edge of the face. Of course, like all these little monos, it would have been even BETTER if they had engineered a way to store/recall patches...especially for live use, and on a powerful synth like this one. 5 stars.
