I played violin in orchestras when I was very young. I would sound awful today if I tried to play a violin, but when I play any virtual string instrument, I instinctively feel how I would use the bow and exactly when I would play vibrato. That's ground into my unconscious from all those years of practice and performance.
I suppose I could use key switches to make the Bohemian violin play like I would, but I don't. I just play the melody on the keyboard.
It sounds like a violin to me, but it's the built-in performer, not 10-year-old me. As far as the bow goes, I often feel like the Bohemian violin is playing me rather than the other way around. It often changes bowing direction sooner than I would. But that's on me--it's capable of doing more.
I have not and will never create mockups of classical music on it. What I do is improvise and write my own music, and the music I write is for the performer to play. I don't feel overly harnessed by limitations.
What I like about the interview with Virharmonic Developer Ondrej Pochyly is the suggestion that the next expansion of BV will let me play it more in my own way, without key switches. Also, it seems like his number one goal is to have their libraries never be outdated.
I never mind waiting for a developer to be ready. Not with the Cinematic Studio Series and not with Virharmonic. Anyway, I love it as it is. Getting more is just a gift, as far as I'm concerned. Maybe not for all you pro composers out there.
I think that Virharmonic might want to consider taking a page off of the Cinematic Studio Series's book and stop estimating release dates for the expansions, except in a very general way. Less information may be better. If more expansions come out in 2019, people will be delighted, just as they were when CSSS suddenly dropped.
