The suggestions for a pop horn section given earlier are probably the best bet. I'm not sure that there a lot of choices for this among the included Cakewalk instruments.
I like Dimension Pro, as it is a remarkable synth instrument with a lot of content. But using it as a ROMpler out of the box, for bread and butter sounds, based on the bundled content has never been its strong suit. In my opinion that's because of a limited number of sample types and articulations for each instrument.
So here are a couple of other 3rd party options to consider.
I think that AIR Xpand!2 has a very good variety of brass and woodwind patches in various articulations and sections. It's a great VST ROMpler to have available that contains many varied real instrument sounds. Not programmable like Dimension, and doesn't have the synth/sampler functions, but is very broad in coverage of bread and butter sounds, and most of the sounds are playable. Has macro controls for attack, decay, release, etc. It is 4 part multi-timbral (compared to the 16 parts in TTS-1), but no General MIDI. Great for sketching up a sequence, or using as background tracks.
This often goes on sale for $1, and was even free at one point last year. Unfortunately, it doesn't seem to be on sale right now. Probably should watch the deals forum here for this to go sale again.

I noticed that PluginBoutique is selling the Garritan Jazz & Big Band 3 for 50% off at $74, that seems to include a lot of brass and saxophones.
