Here is an example of the problem (can be heard on the first couple notes)

The problem is that it seems inconsistent whether a spicatto sound can be repeated in a desirable way. Not only is it note dependent, but different libraries have different requirements for offset, sometimes on a per note basis. Which makes it a nightmare to try and sync them.
Is there any library with solo strings (violin, cello, viola, bass) that is especially good at this bowing effect?
