Thanks Dietz and DG for your suggestions, I am a newbie to VSL and will certainly look into the documentation fo MIR. I am still working my way around.
While I do understand that instrument sounds depend on the stage and make (e.g., stradivari vs guarneri ) the fundamental timbre should be within a certain range for any violin in any stage. That is what I was expecting out of VSL...a clear timbre 'out of the box' without the need for any digital tweaking. But it seems that the timbre is somewhat harsh with VSL and also MIRx and MIR pro seem to my ears to change the timbre, at least for some notes.
Anyways I uploaded two versions of a string quartet Iam working on, one with Algo reverb and the other with Mozartsall, conductor position. You can probably guess which one is which,

I hope someone can give me feedback on the sound qualty and if this is expected out of the solo strings, and if it can be improved.
All this aside, I am thoroughly enjoying the the masterful programming of VSL and their Sibelius integration.
EDIT...just wanted to reiterate that in making this recording I did not do any post processing...it is played straight out of Sibelius notation. I did not touch a single controller on the MIDI keybord. So I REALLY appreciate VSL providing outstanding integration with Sibelius (rather than leaving it to 3rd party like soundsetproject etc.,).
