HI Steve

That'd be a million dollars question,right?

No secret at all,I use Korg Pandora PX4D straight into audio card,
I made review about the unit and there are also some settings I use
somewhere in my sub-board gear section,Pandora topic,be sure to check them both out.
As for doubling,I do not doubling at all.
I record everything in stereo and that's why it sounds kind a big.
Hope I cleared things a bit,let me know if I missed something.
