Having been a violinist from childhood, I am quite familiar with the technique you describe, but I am suggesting that, in music of moderate or fast tempos, it is far more common to use the open string sound than to use the technique you are describing (with sympathetic - - frequency modulation - - vibrato played an octave above). Moreover it obvious that most composers count on hearing anon-vibrato sound when writing for the lowest open string on a string instrument (e.g. the open G at the beginnng of the prelude to Act III of Wagner's Tristan).
In the Vienna Instruments solo viola library there is vibrato on the open C string in
the sustain vibrato patch
the perf leg patch
the perf marc. patch
the perf. leg. (fa) patch
the perf. trill patch (particularly unrealistic).
There is a non-vib open string on:
the non-vibrato sustain patch
the long detaché patch
the fast patches (staccato, spiccato)
The violin is about the same,except that the long detaché patch has an open string vibrato on G.
The cello has open string non-vibrato samples on most of these same patches. The expr. patch has, as on emight expect, vibrato on the open C.
From my experience as a string player the ubiquity of vibrato on the lowest open string of the viola and violin in the VI Solo String library is not an accurate portrayal of string practice. It woud be most helpful if there were a way to change the sample used for these notes to non-vibrato without having to load the entire non-vibrato patch.
