While I see this has great reviews which I am sure are legit, this interface was a big waste of time for me.
I did a lot of research, but apparently not enough. I had no idea that while a simpler inexpensive Focusrite can work seamlessly with most pieces of keyboard hardware, this RME is not enough to power a simple single synthesizer with monitors unless connected to a computer.
Secondly, while RME support was initially quite prompt in answering to issues involved in running necessary updates, they generally appeared to be noticeably unpolished and unhelpful. The update process is not necessarily correct on the RME website, and as many have mentioned on Youtube, tutorial and information videos are best referenced from individual users.
