Yes, I know, I actually was planning on getting VI Pro and a MIRx pack (Teldex, probably) just half a year ago, but I was really surprised that they implemented that too at that price point, and it's totally customizable (not sure if at the same degree as in VI Pro, but still very customizable). Glad I didn't buy those, though, specially knowing that I won't likely use the older VI Instruments VST anymore.To note, this was also a feature of Vienna Instruments Pro 2 plugin/software which is a separate purchase to the VI Standard or Full libraries as well as the VI Special Edition. If you own that plugin you can use the humanize function with the VI Special Edition libraries. The Synchron-ized version doesn't appear to have any new functionality compared to Vienna Instruments Pro 2. Nevertheless, it is a very useful feature and now you don't have to pay extra for it (or something like Synchron MirX)!
VSL released a quite excellent video that discusses a number of features that are now also present in the Syncrhon player in a musical context here, which I found quite enlightening:
The only thing I miss is mapping the velocity XF exclusively to longs (and legato, of course) and not the shorts, although that's something I guess I have to learn, I guess it's possible. Oh, and having the lower velocities trigger the portamento, that would be great! But, as I said, I think it's a matter of fiddling with the new engine and knowing what does what. I still remember when it looked like this. :D
