Wow! Just got Quantum Leap Brass. This stuff is incredible. Really different from all the other libraries. I mostly use orchestral samples and I was really impressed by the dynamics of the french horns. Orchestral trumpet is really strong too. I layered the staccato tuba, staccato solo trombone, staccato 4 french horns and the staccato trombone section - HUGE is an understatement. Got to check out more sounds.
