I normally use an RME UFX which has a firmware based mixer allowing you to create submixes independent of the computer. It’s built into a rack along with other devices including my in-ears wireless transmitter, my eigenharp interface, a network router and stuff. However, for something I"m hoping to do soon, I need a simpler system so I can just carry audio interface, keyboard and laptop. I only need inputs to get a mix from the band monitoring system but I would like there to be a firmware mixer so I can create submixes without using the computer.
Anyone know of a really good sounding audio interface with the above functionality? I’ve thought about the RME UCX but it’s really expensive.
