Bill,
The first, absolute first thing that you have to understand, ASIDE from Real Tracks, Band In A Box has no sound of it's own. Even the Real Tracks is rather limited as far as sounds are concerned.

Since BIAB has always been, and remains, a MIDI orientated program, and requires a synthesizer to produce the sounds, the sound you are looking for must be in the synthesizer. Whether or not the synth YOU are using has the sound, I do not know. If it does, then you can use it. If not, then you can not get the sound you are looking for.

Because of the specialty that you are looking for, it is unlikely that any of the Real Tracks will have that, but you should audition them to see if there is a sound that is comparable. Other than that, tell us what synth you are using, if any, and maybe someone knows if that synth has a patch that will meet your needs.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
