This may be stupid, but is your master gain fader at 0db when you mix down?tweakin wrote:When I render from Cubase (32bit float WAV), then Import to Wavelab to use mastering tools, the sound is clean and sharp- quite similar to what Cubase plays back (only a few db quieter?!?), but when I use my mastering plugins and tweak the sound, I then "save as" (as a 16b/44k), the sound is heaps lower still when I play it back again...
Also, are you using SX 1? I seem to remember there was a problem with the way the pan laws worked in playback vs on mixdown, resulting in lower mixdown levels.
