Behringer Four LFO Euroack modulation source
2,5 / 5,0 | 
The Four LFO is Behringer’s take on that solid source of modulation, the XAOC Batumi. It offers excellent LFOs in a cheaper and less lovely package.
Four LFO
We already know that Four LFO draws heavily from the Batumi, and the debate will no doubt continue to rage about whether that’s a good/decent thing or not. XAOC did make the Batumi firmware open source, and Behriner has also made the odd change to the hardware. Most notably, it’s bringing the “Assign” options to the front panel rather than having them around the back as they are on the Batumi.
The general idea is that you have four independent but also syncable LFOs. The LFOs are represented on sliders with glowing LEDs showing the speed and movement of the voltage. Each LFO has three simultaneous outputs giving you a permanent sine and square wave plus an assignable output. The Assign output can be switched between ramp, triangle and trapezoid waveforms. The four channels are not separately assignable; they all take on the same shape.
The LFOs can run freely, or you can run them in Quadrature, Phase and Divide modes. Quadrature takes the first LFO as the master and runs the other three at 90-degree, 180 and 270 angles respectively. Phase mode is similar to Quadrature mode, except it lets you set the phase shift of each. And Divide mode sets LFOs 2, 3 and 4 to time divisions of LFO 1. The LFOs can be individually synced to a clock, and they also have reset inputs.
The Batumi is a brilliantly useful LFO source to have in your rack. The Four LFO offers the same functionality in a slightly wider, less beautiful and cheaper package.

Nice to have! Maybe I will get it, because of the sync option and the price, it could be useful….. I have the doepfer Quad lfo, nice to have it, but no sync….. So get it or not? Maybe!
The purpose of open source is to leave knowledge to mankind, which will help mankind to do their good. There is nothing Behringer has done wrong here, even if some try to misunderstand something here. But everyone, every company has the right to develop their products based on open source. So for me, I am happy with this!
