The Behringer 2600-VCO Analog VCO Module is an authentic reproduction of highly revered, vintage 1970s circuitry in a compact and highly flexible Eurorack module. Featuring four simultaneous waveforms including sine, triangle, saw and pulse, you can drastically alter the timbre and character of your sound quickly and easily. Each of the four different waveforms offers a tremendous range of frequency control from 10Hz - 10kHz or 0.03Hz - 30Hz in LF mode with a Fine Tune dial to precisely set your frequency to integrate with external modules, hardware or instruments. A host of connectivity options means that the Behringer 2600-VCO will seamlessly fit in with the rest of your modular system thanks to individual outputs per waveform to patch into different modules for unique and interesting sound design. Not only that but the Pulse Width Modulation can be simultaneously controlled manually and via CV input. An often-overlooked section of your modular synthesizer, the VCO is the heart and soul of your sound, with the 2600-VCO, it's never been easier to achieve the full-bodied and characterful sound from one of the most celebrated synths in history.
