Re:Bouncing Tracks - Sequential vs Simultaneous
Forget bouncing, have a look at Freezing tracks. This is what you need if your compy is struggling.
I don't know how the structure in SONAR works exactly, but bouncing each effect separately will either be exactly the same (ie the math is no different) or there will be losses from the rounding. Depends on how SONAR works in that respect. If there is a difference, it will be VERY small, as Beagle said. Actually, there would be a difference. When performing one plug bounce, SONAR steps up to 64 bit, does it's stuff, then exports your bounce at 32bit (standard). There will be rounding loses here. But if you do it all at once, it stays in the 64bit domain up until the final bounce back to 32bit. But if you set your bounces to 64 bit then I assume it would be the same.
You can do a simple test by making a track of either bounce type, lining them up perfectly, flipping the phase on one of them, and summing together. If there is ANY noise at all, then there has been a loss in information. And you now have that loss right in front of you.
