Testimonials
Love your libraries, they're unique and focused and at least personally speaking, not overcoded!
– Gareth Coker, Composer (Ori and the Blind Forest)
I own 9 String THeories Libraries and use them in lots of my productions from orchestral to rock to pop. Small in size, big in sound, super fast load times, high quality! Love these!
– Carlos Villalobos Jr, Grammy nominated composer
