Hi. Does anyone know of some good plug-ins? I need strings (orchestra), choir, grand piano, electric guitars and some percussive like glockenspiel and music box. Rock drums wouldn’t hurt either.
Thanks in advance.
It’s all opinion but, for what you describe SampleTank 3 does a fine job for all the sounds listed. Of course there are others that cost less and more. SampleTank is not cheap but, not the highest either… 
Good luck.
Regards.
