As explained in chapter 26.5, the hardware input of channel 1 now no longer feeds the record
software, but is still connected to TotalMix (and thus to the Compressor). The record software
receives the signal of submix channel 1 instead – the Compressor's return path.
26.7 MS Processing
The mid/side principle is a special positioning technique for microphones, which results in a mid
signal on one channel and a side signal on the other channel. These information can be trans-
formed back into a stereo signal quite easily. The process sends the monaural mid channel to
left and right, the side channel too, but phase inverted (180°) to the right channel. For a better
understanding: the mid channel represents the function L+R, while the side channel represents
L-R.
During record the monitoring needs
to be done in 'conventional' stereo.
As TotalMix can invert the phase, it
also offers the functionality of a M/S-
decoder. The menu

a macro to simplify the setup. First

After a mouse click TotalMix sets gains and pans correctly. Of course
these settings can also be performed manually. Repeat the last step to
remove all routings (

).
The M/S-Processing automatically operates as M/S encoder or decoder, depending on the
source signal format. When processing a usual stereo signal, all monaural information will be
shifted into the left channel, all stereo information into the right channel. Thus the stereo signal
is M/S encoded. This yields some interesting insights into the mono/stereo contents of modern
music productions. Additionally some very interesting methods of manipulating the stereo base
and generating stereo effects come up, as it is then very easy to process the side channel with
Low Cut, Expander, Compressor or Delay. The most basic application is already available di-
rectly in TotalMix: Changing the level of the side channel allows to manipulate the stereo width
from mono to stereo up to extended, stepless and in real-time.
