I asked the question about the track delay for VSL Synchron Woodwinds, because I have - once again - started a template, this time with all my orchestral on a local VEPro and on a PC VEPro. Following the guidelines from David I have created a long and short version for every instrument. I have far too many libraries and the main part are from VSL, so this discussion about "to track delay or not to track delay" made me test a VSL Synchron Strings Pro staccato (short) patch + Synchron Strings 1 long patch against a snare from Superior.
As expected the snare is right on the beat, but I found that a track delay of -70 ms was needed to make the staccato strings line up and surprisingly the long string patch also sounded quite on time with a delay of -70ms.
Please take a listen and let me know if you think that I'm right about that!
