Hi Nicoloa,
there is no difference in the samples. The changes made in the Syn version are available as update for the VI version as well (look in MyVSL).
The main differences with the Syn version is:
- Included reverb, panning (different presets), but you can disable that and use the dry sound like in the VI version
- matching volume with all Synchron / Synchronized instruments
- ready configured Violin II section
- new and modern player with some additional cool features (but things like auto-divisi and sample stretching is still not implemented)
In short: the Syn version is ready to use: Just load the instrument and start composing / programming.
Is the upgrade worth it? If you have problems finding the correct panning and reverb settings or don't have the time to tweak them, it's imo definitely worth it. The included IR reverb is just perfect, and it uses less CPU power compared to MIR Pro.
Best, Ben
