Quad LFO with Assignable Waveforms for Eurorack. Expand your synth setup and create even more intricate effects with the Behringer FOUR LFO. This compact Eurorack module comes with 4 voltage-controlled LFOs based on the incredible open source Batumi from Xaoc Devices. Each LFO comes with separate user-assignable waveforms and offers a slew of options for you to sculpt unique sequences and waveforms. The FOUR LFO provides a uniquely flexible platform that allows you to change and shape various waveforms and patch them into different effects to create wild and otherworldly soundscapes. Additional controls on the FOUR LFO include a zoom mode so you can more precisely dial in frequency settings; a reset and sync input for each channel; independently assignable reset and tap tempo inputs and LFO saw, ramp, triangle and trapezoid waveforms.
