BEHRINGER PRO-1 

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

Authentic 80's Analogue Circuitry is Back

Inspired by one of the most influential monophonic analogue synthesizers from the early 80's, the Behringer PRO-1 semi-modular synthesizer packs a huge range of classic synth sounds in a convenient desktop module.

Use it on its own without patching anything, integrate it with a Eurorack modular synthesizer environment, or even combine multiple PRO-1 modules to create a monster poly synth — up to 16 voices!

However you use it, PRO-1 is sure to impress with its all-analogue signal path, vibrant four-pole analogue filter, and built-in arpeggiator and step sequencer.

Whether you want to conjure the classic bass and lead sounds from the 80's, or simply want to expand your analogue synthesis capabilities, there's big value in the Behringer PRO-1 semi-modular analogue synthesizer module.

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 analogue 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 analogue 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 1980's and 90's 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

The Behringer PRO-1’s 3340 Voltage Controlled Oscillators (VCO's) 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 VCO's 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 VCO's 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 1970's and 80's predecessors.

Rock Right out-of-the Box!

The Behringer PRO-1 comes ready to rock, thanks to its default signal routing that doesn’t require lifting a single patch cable to instantly create amazing sounds.

The semi-modular architecture lets you easily tap into the inspired sounds of 1980's and 90's progressive rock, wave, EDM and synth-pop music synthesizer tracks that made rock and roll history – or to design incredibly fat and original sounds that will make you a legend in your own right!

The Envelope, Please...

Make that envelopes! The PRO-1’s Low Frequency Oscillator (LFO) features your choice of Sawtooth, Triangle and Pulse waveforms with a sweepable frequency range from 0.1 to 30 Hz – plus 2 separate Envelope generators for modulating the VCF and VCA.

Onboard Sequencer & Arpeggiator

The Behringer 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, mesmerising and totally addictive...

The LFO, the Matrix & More…

Thanks to its dedicated and fully-analogue LFO, PRO-1 lets you choose from triangle, pulse or square waveforms and features a single Frequency control for ultra-easy operation. Additionally, the onboard Modulation matrix lets you set the Amount of Filter Envelope, Oscillator B and LFO modulation is applied to the signal, and how.

You can even modulate the pulse wave via the LFO, envelope or manually – for sounds ranging from mild to wild!

Controls & Connectivity

We just can’t help ourselves – like you, we're gear-heads, too.

For those who want the numbers, PRO-1 has 56 controls, all laid out in a highly-intuitive format that puts the joy back into your music creation. And you can expand PRO-1’s tone-sculpting capabilities beyond your wildest dreams by utilising the patchbay for incredibly vast and flexible patching options!

Drone mode — explore endless soundscapes

When it comes to creating ambient drone sounds, the Behringer PRO-1 has you covered with its switchable drone mode. Just like it sounds like, drone mode turns the PRO-1 into an "always-on" synth, no need to trigger notes or envelopes.

It's perfect for recording soundscapes, layering an ambient bed under your other synth and drum sounds, and much more.

Create a monster with 16-voice Poly Chain capability

As a single-voice analogue synth with vivid oscillators, a delightfully fat filter, external audio input, and a ton of patch points, the PRO-1 synth module represents big value on its own.

And with support for up to 16 voices in Poly Chain mode, you can keep adding modules to your rig to add more sonic potential. Simply connect each PRO-1 module to the previous module's Poly Chain output to add another synth voice.

Ready for Eurorack

The Behringer PRO-1 module is a sweet synth for desktop use on its own — and it really shines when you start patching it in with other modular synth gear.

With lots of patch points to play with and ample controls for hands-on sound shaping, the PRO-1 module will definitely get a lot of use in your productions.

Unleash Your Imagination

When it comes to not just pushing envelopes but creating them, PRO-1 gives your imagination its voice – and it’s so very affordable.

When modern performance calls for classic analogue sound – it calls for the Behringer PRO-1!
