I have an RML16. Today I took it out of its box to test it, but it only gives me red light. I do not have a computer with a firewire port, but since I just want to mix it live, download only "UC surface" and tried to make it run but always RED LIGHT.
When you just bought the mixer, do you need to download capture and studio one? I can not just download uc surface and use it as normal mixer?
