Well, what I mean is that it's not possible in TotalMix to split the hardware outputs (eg AN3/4 into AN3 and AN4).
So if I want to route the Hardware Input 3 into the hardware output 3 only, the only solution I found is to pan hard left, otherwise it will be played either in outputs 3 and 4.
And if I want to route hardware input 3 into outputs 3 and 4 at different levels, I can't because the outputs 3 and 4 work as a stereo output couple (2 physical outputs but only one channel). So again I have to work on the pan of input 3 to reach the balance I want, which is not a very accurate way to proceed.
For example how can I route a signal from channel 3 of the DAW at 6 different levels into 6 mono outputs (used as mono returns or mono phones)?
So my question was : is there a way to split the stero output into 2 monos channels in TotalMix with the same "Stereo" button that you find on the inputs settings?
