Had the chance of getting my hands on this London Solo Strings library. But I've only seen the Viola.
I've not yet seen a review nor any comment exceeding 1-2 lines about this library. Strange huh?
Well i wanted to put a comment or two about it here:
Per articulation it has about 3 sounds per key mapped in the respective velocities. Unfortunately to get something hearable you have to press the key relatively hard. At about middle to 3/4 you get a relatively slow fade in. Hit the keys hard if you want a standard sound for quick notes. I find it not really convenient to play, rather annoying by the way the velocity is mapped.
The violin has the most articulations (26) the Viola only 16 (you can look them up) half of which I find not really helpful such as the "Viola short" and "Crescendo short/med/long" since one could simply modulate these articulations. They might be handy though when you want a constant fade in sound. Arco is the only real usable articulation for mainstream play but a key doesn't last very long you have to hit it again to sort of simulate a bow change. The keyswitch load has 4 KS for Arco/marc/spic/piz for live play. There is also a quartett instrument of all 4 mapped out in their respective zones across the entire keyboard. As far as I've noticed it plays not more than 1 voice when you hit a key.
But I guess you wanna know how it actually sounds lol. Just like from the audiodemos it has a authentic, dramatic and passionate sound and a nice vibrato (that you can't change). The vibrato varies from the velocity layers in MF seems to be passive at first and then fade in while at F it's stable and that's it with the customizability.
If you want to use it professionally, you got to erase the inscripted reverb (not convolution) first everytime, or save the kontakt state in your application.
Besides that I find it ok if you want to use it simply for composing solid string quartetts, the sound is simply "nice" but I'm not an audiophile nor have I really good ears.
The prize seems to be at about 350$. I don't know what to think about that since for 550$ you can get the 20gb package EWQLSO. London Solo Strings hits 4 gigabyte.
In my opinion LSS should be cheaper since it's programming is relatively simple. It wouldn't explode if there were atleast 1-2 more velocity layers of samples in the Arco articulation and a non-vibrato one that is clearly missing.
I hope this helps someone, questions welcomed.
