For this price this is a great analog synth, more than that... I haven't had any complications using it. The sound is fat like a real moog. Using it with ableton and sending midi via usb works like a wonder. Did'nt even have to install any drivers. If there is anything Behringer could improve, it would be a vst plugin to control the parameters and be able to automate them. Also, the DC cable could be a little bit longer and of better quality.
