Authentic '80s Analog Circuitry is Back

Inspired by one of the most influential monophonic analog synthesizers from the early '80s, 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-analog signal path, vibrant four-pole analog filter, and built-in arpeggiator and step sequencer. Whether you want to conjure the classic bass and lead sounds from the '80s, or simply want to expand your analog synthesis capabilities, there's big value in the Behringer PRO-1 semi-modular analog synthesizer module.

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 analog 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.
