Behringer Pro-1

Synthesis Types: 

Inspired by a legend. The Behringer Pro-1 Analog Synthesizer is a faithful recreation of a classic monophonic synthesizer that shaped the electronic music sound in the late 80s and early 90s. The Pro-1 Analog Synthesizer employs dual 3340-type chip oscillators and a 3320-type chip 24dB 4-pole filter. These premium-grade chip circuits deliver classic analog grit and warmth, allowing you to generate powerful sounds on the fly.

Real analog sound

The dual VCO design of the Pro-1 beautifully recreates the classic sound of its predecessor. It utilises 3340 and 3320 semiconductors so you can faithfully recreate the iconic timbres of monophonic synthesis. You can use three simultaneous oscillator shapes - for Osc A these are Saw, Pulse and Osc B has Saw, Triangle, Pulse waveforms. This gives you a wide palette of sounds for you to develop your sound with.

Extra special effort has been given to the design of the Pro-1. It features true analog circuitry meaning that you get amazingly warm tones with minimal effort. The VCO, VCF, and VCA are combined to give you that classic sound performance. This focus and attention to detail has given the Pro-1 it's unique, vibrant, and complex sound.

A huge selection of controls

Allowing you to dive deeper into the sound creation - the Pro-1 is built for experimentation. In order to allow you to take control, the Pro-1 has 56 controls, buttons, and dials. The layout is clean and intuitive meaning you can experiment and perform the way you find most comfortable.
