If you have the RAM, the SSD space, and the time to learn it, buy the Chris Hein Horns Pro Complete . It is the last brass library you will ever need. For everyone else, the standard Chris Hein Horns Compact (a lighter, cheaper version) might be a better starting point.
The library features a complex but unified UI across all instruments, providing: DSP Effects : Includes 6 integrated effects (EQ, Compressor, etc.) and 21 high-class convolution reverbs Transient Designer
: Reviewers note it offers "modeling-like" control over individual instruments, including independent LFO-vibrato types
