Actually, I'll look into the possibility of changing the listed faders in the mixer, but it's not a big deal as long as I remember how to use them. I must say, it is really cool to get an answer about this from a notable physicist as such as yourself! I have learned a bit about the Unruh effect earlier, and I think another student did a Master's degree on that subject under Prof. John Magne Leinaas here in Oslo, so I recognized your name immediately... Well, thanks again for the info.
