I have recently got a microbrute synth. I updated the firmware and everything seemed fine then it has just stopped making sound. I have tried reverting to the basic patch, checked all my connections, tried different cables. I am not a noob to all this, it looks like the synth has a fault. I don't know whether it is to do with the firmware or it is just the synth but I have only had the microbrute a day. what can I do?
