A B C and D are all mono ins, only stereo if combined
Just set to a single input (like A) instead of AB or CD (or A+B/C+D)
A is only left if paired with B, etc.
For your application you could have:
A4 Left to OT A, to a thru machine input set to “A” only
AR Left to OT B, to a thru machine input set to “B” only
WMD Out to OT input C with Recorder for Flex track set to “C” only
106 Out to OT input D with Recorder for Flex track set to “D” only
With the appropriate recorder trigs and playback trigs on the respective flex tracks and corresponding record tracks set accordingly.
They will all play out Main or Cue across both the Left and Right outputs by default However, you can have them all go out in through four single outputs by setting each like this:
First set the project to “Studio” Mode (this allows for four mono outputs: MainL, MainR, CueL, and CueR)
A4 thru machine panned hard Left, Main vol 127, Cue vol 0
AR thru machine panned hard Right, Main vol 127, Cue vol 0
WMD flex machine panned hard Left, Main vol 0, Cue vol 127
106 flex machine panned hard Right, Main vol 0, Cue vol 127
You could set track volume lower than 127, but in my experience for this type of application is better to keep track vol at 127 and attenuate volume at the AMP VOL setting.
In this way you have four mono signals going in, being processed etc and going out in mono, separate the whole way through the signal flow, out into four separate mixer channels for example.
This is how I actually run my OT as a matter of course, just with different names for the hardware, etc; and different input assignments depending on the situation (like if I do want stereo input/output for a given application)
Hope this helps. Took me a while to get it down in the beginning.
