its for sure not going to sound like 4 horns playing a chord, but not as big as 16 horns thats for dang sure. Add on top of it reverb and other things. Just lower the volume and mix/match solo/ensemble samples, even less like 16 [:)]
Herb's right that oyu need to pan them slightly different.
There are other issues that arise of course. As the solo samples are THE SAME INSTRUMENT, so no matter what you dont get the varied nuance of different instruments. This alone is one reason to mix ensembles if you dont have other solo horn samples (IMO). It may take some EQ and volume adjsutments (maybe only use the sparkle from the ensemble, or only the low mids, or a little of both..etc).
The only REAL issue with mixing matching ensemble of course is that you get that "chorus" sound on on note, but its usually buried enough, especialyl with reverb, to go unnoticed.
