Alternative solo strings update

I’ve recently purchased Alternative solo strings and been debating quite some time whether to go for this or the Solo Strings library instead (I already owned solo cello and violin and they are incredible). After installing I instantly wished there were more articulations for each instrument and legato (or performance) patches for bass and viola too. I have to say that I’m glad to have finally settled for the Alternative library, The sound is incredible, very detailed and dry which is the primary reason why I was looking for something like this. The only downside is that not including the same articulations present in the Solo Strings, it feels a bit outdated or at least not as complete. If possible I would absolutely love to see an updated version of Alternative Solo Strings, possibly including these other features, legato versions of viola and bass and a controllable vibrato too. Thank you for your consideration.
