A long time ago, before Giga 3, someone told me that MIDI panning (using the pan controls in Sonar) is not a good idea, because it's not "true" panning, and you lose stereo information. He said to pan using the DSPs in Giga.
Now that Giga 3 is out.. does this still hold true? I notice when I pan in Sonar, it changes the panning on the mixer in Giga.. but not the DSPs, obviously. Is it OK to use Sonar to pan? Am I "losing" anything by doing this? Or should I still use the DSPs to do panning, and set up left/right/center DSP presets?
