Ah now I see, thanks Noah.
If I had a MK8 and a MK41 and wanted to record raw, I just keep them as separate channels and record normally as ISOs - yes? With this scenario I would then need to do the flipped of the phase, etc? Or does the DAW do it?
If you aren't using the recorder's Mid/Side
recording mode and record each channel directly, you'll record ISO Mid and Side channels.
The three primary options for converting from the ISO Mid and Side recorded channels are to-
1) Use the recorders Mid/Side
playback or monitoring mode to listen to or otherwise output L/R.
2) Use a plugin or the built-in Mid/Side conversion features of a software editor to convert to L/R.
3) Use an analog mixing desk or software multitrack editor to manually convert to L/R by:
Bringing up a copy of the raw Side channel in a second channel strip, inverting polarity on that channel, panning the non-inverted Side copy hard left and the polarity-inverted copy hard right, linking the two Side channel levels so their faders move in unison, bringing up the Mid channel on a third channel strip panned to center, and adjusting the Mid/Side ratio via the relative positions of the single Mid fader and the two linked-Side faders.
You only need to do the polarity-flip thing with the third option.
