Audiobro Modern Scoring Brass. The scripting and all the detailed tweaking that can be done would be great, but the samples suck! The instruments mostly sound awful(I'm talking tone-wise, not even scripting. The trombones don't even sound like trombones) and/or are very difficult to mix especially with eachother. The library takes gigs and gigs and is still missing a ton of dynamic range. It sells itself as a library that takes a lot of tweaking-and it does, but the results are honestly never even close to other libraries IMO. The content simply isn't there to be manipulated.
That's all not to mention the performance issues I've had. It seizes up constantly (I'm talking several seconds of the interface freezing happening randomly but frequently on the scale of only dozens of seconds in distance) and saving a project with any of these instruments loaded takes significantly longer than with any other library. But hey, performance issues can just be my own system not playing nicely. Your mileage may vary.
