Welcome to the forum from another trumpet player.

Garritan JABB is pretty reasonable when compared to the price of some dedicated horn libraries. I confess I haven't kept up with all the possibilities because writing and recording horn parts is something I do for other artists on their CDs.

Just a comment on the 'strings' part: BIAB has long outgrown the original choices of instrument buttons shown. Styles, both RealStyles of RealTracks and MIDI parts including HQ tracks can be many instruments. Since most songs still have drums and bass etc. these other instruments can often be found on the strings or guitar track, and even piano. Just make a mental note of what's what. [On a hardware mixer, I would use masking tape and a magic marker to make a scribble strip.]
