everything is ok, but ...
I write a lot of for string quartettes were I use from the notation folder the solo violins (Guarneri, Strad etc.). But for my ears the sound very "sharp" . I am missing the warm resonances from the body of the instrument or a full tone. So they are also not in balance with the violas. It seems that they would be played near the bridge.
Is there a way to get a warmer sound also in the middle range of the playable spectrum?
Sorry I couldnt express it more clearly but if wanted, I can post a mp3.
