My problem is that the audio that comes out of Gigastudio 2.54 at 44.1k is perfectly fine, but at 48k I get aliasing noises, especially on transients. Like very high pitched resonances. It's quite noticeable when I turn up the treble on a bass pizz or a timp sound for example.
I initially thought this may be a clocking issue, but I've tried all varitions of master/slave - using different destinations - either into ProTools or into a Motu828 (I use a hammerfall 9632 as soundcard for the Giga PC). The bottom line is that it always sounds good at 44k but dodgy at 48k.
Is the sound at 48k perhaps cleaner in GS3? Has anybody come across this? Any help would be greatly appreciated.
