Sorry I didn't see this before. Thanks The Darris for your answer. It calms down my thought that I had bad samples here and there.It's the harmonics of the instrument resonating in the studio. This, to me, is a natural characteristic of the instrument. However, some careful EQ'ing can help tone it down if it is too much for you. You won't get that with VSL because of the fact that they recorded it dry. Dry rooms won't pick up on the harmonics as much.
VSL has a perfect tuning that at times felt too perfect. Only the humanization feature will help. Nevertheless, having now the spitfire woodwinds, even thought I love the sound of them, I miss that "perfect tuning " because some times I find some notes in some instruments to be a bit too off, specially the release samples. I am sure now, that it's better to combine samples, maybe SSW with orchestral tools woods combined. I also miss the "runs" a lot in the SSW samples. Nevertheless, the runs in VSL were not tempo locked, which was a bummer. You could only get the tempo lock working by using the additional "sequencer" tool that VSL instruments pro has (up to my knowledge). Anyways, thanks again Darris.
