Behringer Four Lfo, Modular Lfo Synthesizer

The Behringer FOUR LFO is a compact Eurorack module that delivers four voltage-controlled LFOs based on the acclaimed open-source Batumi design by Xaoc Devices. Each LFO offers user-assignable waveforms including sine, square, saw, ramp, triangle, and trapezoid, with a frequency range spanning from 500 Hz down to an ultra-slow 28 hours. The module features four faders for real-time control, plus modes for free, quadrature, phase, and division operation, along with a zoom mode for precise frequency adjustments.

Connectivity includes reset and sync inputs per channel, assignable reset and tap tempo inputs, and outputs for sine, square, and assignable waveforms. The FOUR LFO also provides a USB port for easy firmware updates. Designed to fit standard Eurorack cases, it requires 12 HP of space and draws 95 mA on +12V and 69 mA on -12V. This module is ideal for creating evolving modulation, complex rhythmic patterns, and experimental soundscapes.
