It's obviously the color of all the cables!

If you simply go out and purchase yellow cables for all your left channel audio runs, and green cabels for all the right channel audio runs you be feeling relieved that they are sorted.

If a synth isn't doing it properly, make it sleep outside for a night like the dog he is. You'll see a new attitude the next day when you open the door and let it back in.

I guess this doesn't make sense, but it doesn't really have to at all.
