"Stereo"
Well, I suppose everything depends on the recorder, and I don't know anything about this Korg machine, but in theory, you shouldn't gain anything by recording the same thing onto two different tracks. Yes, it will be louder relative to the other tracks, but presumably you can accomplish the same thing if it's on one track simply by raising the fader on that track (okay, maybe you have to lower the faders on the others if you've run out of travel).
This is distinguished from ways you might record different things to two tracks, such as:
- "Real" stereo, with two mics on the same source (which you'd likely pan hard left and right at mixdown) in some arrangement like XY, ORTF, spaced, separated by a disc or mid-side (with a matrix to print to two tracks).
- "Pseudo" stereo, where the two tracks start out the same, but you make them different by putting a delay or something on one or both.
- Multi-mics for other reasons (which you might pan any number of ways), like one close up and one for room sound, or maybe you just use two mics because you don't know which will sound best in the mix.
- Full-on double-tracking, where you record the vocalist singing two whole separate passes through (here you'd tend to pan them both to the same place, like the middle). This can make and iffy vocalist sound better. You can also "comp" them.
that's mostly what I am doing.
