Right now, the GOS library is all ensembles, 1st violins, 2nd violins, combined 1st and 2nd, violas, cellos and basses. There are apparently a ton of solo violins that are recorded also but that will be a whole other library I think or a huge addition to this one. Right now this is the king of strings ensembles and Garry will do the same for solo strings that he has done for ensembles. As I always say, prepare to be humbled.
Hope this helps
