Quote akkk:yes, BUT have you made sure you have MUTED the channel you are recording TO. Otherwise it will be routing back into the mix through the output going to the summing mixer and will cause a weird phasing in the mix.
Sure your not listening back to the mix back through the same output whilst recording it? IE - is the channel MUTED that you record to OR is it going out to an output that is not part of the summing mix.
Nothing is coming out from rme while recording, there is no loop, I remove all the output cables, only recording inputs of RME. I listen with headphones out of rme headphone socket if I need to, but don´t make any adjustments at this point.
You said you were recording the output of a summing mixer? Well whats feeding the summing mixer? Are you accidentally sending the mix down to the summing mixer?
