Here’s what Behringer say:

Making its debut in 1981, the monophonic Sequential Circuits Pro-One quickly established itself as the synthesizer of choice for numerous artists including: Thompson Twins, the Prodigy, Depeche Mode, Vince Clarke, New Order, Prince, Soft Cell and a host of others. An ultra-affordable homage to that iconic synthesizer 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!

True to the Original

Great care has been taken in engineering the PRO-1, including the true to the original analog circuitry, legendary VCO, VCF and VCA designs, all of which combine to make it easy to recreate the classic sound performance. This highly-focused attention to detail is what gives the PRO-1 its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects – and all the way out to the otherworldly sounds of your imagination.

Big, Fat Tones

The inspired synthesizer tracks laid down in the 1980s and ’90s are etched in the annals of progressive rock, wave, EDM and synth-pop music forever, making them truly classic in every sense of the word. The PRO-1 lets you recreate all of that magic – or design incredibly fat and original sounds that will make you a legend in your own right!

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.

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.

16-Note Poly Chain Ready

While it is a monophonic instrument (one note at a time), PRO-1’s 16-note Poly Chain function lets you combine multiple synthesizers for up to 16-voice polyphony – plus provides vastly improved reliability and stability over its 1970s and '80s predecessors.

Onboard Sequencer & Arpeggiator

PRO-1’s dual 64-note sequencers allow you to record and playback your choice of 2 unique patterns, which can be played either in Keyboard mode, where you create and store the pattern, or Step mode, which allows you to interact while composing the pattern. The onboard Arpeggiator switch features 3 positions, Up (ascending), Down (descending) and Off. Both sequencers and the arpeggiator are fun, mesmerizing and totally addictive...

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.

Mr Eric Standen19th Jul 2021

Berhinger have had a lot of bad press lately because of there pursuit in bringing affordable gear to all but they have done it again with the Pro-1. I’ve never owned an original let alone played one but the sound of it on countless Eighties songs can’t be wrong. It’s small, a fraction of the size of the original but still looking as good. It sounds great and no doubt in better hands than mine an A /B comparison would reveal many similarities. Although the manual leaves a lot to be desired if you do a search for the original Pro1 manual online that would be a great starting point. It has helped me. I can’t comment on build quality as I’ve not had it long enough. But, as with any instrument, treated with care it should last. What’s not to like for an inexpensive foray into analogue synthesis.
