Okay, so I'm using 64 bit Logic to record Ivory II Italian Grand as a midi track. Okay, so if I just bounce, with default settings, I suppose that Ivory is converted to 24 bit aiff and then on to 16 bit without dithering. Okay, yeah, I'm just trying to figure this out, bit by bit, as it were. So, to recap: I played a tune, bounced, imported to Waveburner 1.6x then went to 16 bit 44 whatever for a CD. I noticed my tracks sounded a tiny bit bad, which they were actually 8 bits bad, because Logic send a file with rounding errors on to Waveburner because I accidentally had it set to 16 bit no dithering. Okay, so I should have checked the 24 bit box, no dithering to make the Ivory tracks retain the best sound, without truncation or dithering at that point. So, okay, I get it now if that is what is happening with Ivory 2. I mean, the fact that it's now 64 bit and I'm using Logic 64 bit refers to data, not audio, yah? Or no? Yep, pretty sure that 24 bit AUDIO (aiff.) is what I want to export to Waveburner for mastering. Then, (I have to re-record the whole album i.e. bounce 24 bit no dithering) after doing everything I want to do with the whole album in Waveburner, burn my CD with it set to dither going down to 16 bit. Okay, so that's what I'm going to do then, re-record everything. Maybe I should bounce in place? Do you? Am I, er, on the right track? Just a nod or something, eh fellers.....Maybe this is partly an Ivory 2 question, maybe Waveburner....a lot happens when one hits that "bounce" button.
