If you would also give the option to patch bus outs back to input channels, or at least allow free routing of the FX rack units it would make M-S processing possible 🙂
you can select the stereo image options in the preamp
Stereo Image–This section is visible only when a stereo input channel is selected.Touch the mode to select from the following options:L/R = standard left/right.R/L = switched left/right.L-Pol/R =standard left/right with switched polarity on left.R-Pol/L =switched left/right with switched polarity on right.Mono =left and right fed to both channels.L/L = left fed to both channels.R/R =right fed to both channels.M/S =for decoding a mid/side array (outputs M+S/M-S).
For normal M/S use, the mid signal/microphone should be patched to the odd channel and the side signal/microphone should be patched to the even channel.The width control can be adjusted in 1% increments from Mono (0%) to Stereo (100%).
