I've been going through the instrument sounds in my score manager. I noticed that 1) many of the brass instruments only play as a group of them in unison, like the trumpet. Is the "chorus" effect the sound of the sample itself? Or is this caused by a midi controller for the "chorus" effect? I want to make it sound like one trumpet.

By the way, the trombone solo seems to sound fine.

My other issue is that most instruments have vibrato. Is the vibrato part of the sound itself, or caused by a "vibrato" MIDI controlleer setting that can be adjusted or set to 0?
