You could create your own RealDrum set to play just the shots/holds you need but you would need to use F5 to change drums then F5 again to return to normal drums.

Or you could edit the real drum text file (use ; in front to comment lines out) so it only has one shot to choose from, and even add that shot as a custom made one to the end of the wav/wma file, just backup the original text & wav file and experiment with it.
292 is the bar that the shot is on (with the track starting on -1 then 0 as the 2 bar countin) just drag the real drum track into RealBand set to the same tempo as the drums.

Here are some examples of defined shots:

Shot,1,82,-2,455,1,100
Shot,0,83,5,360,1,90
Shot,1,171,240,200,1,80

The six elements that come after the text "shot" are explained here in further detail:


Type of shot
The type of shot needs to be either 0 or 1. If 0 is entered, the shot will be used when chords are entered with two periods (shot) or three periods (hold). If 1 is entered, the shot will be used when chords are entered with two or three carets before them (8th & 16th note pushes).

Bar number in style wave file
Like with patterns, you need to remember that RealDrums styles use -1 based numbering, so you need to subtract 2 from the bar number as you see it in your audio editor. More than one shot can be played in a single bar, and you would use the tick adjust amount to distinguish between the two.

Tick Adjust
The shots do not necessarily have to occur at the bar lines, and the tick adjust can be used to tell Band-in-a-Box® exactly where the shot starts. Simply measure the number of ticks from the downbeat of the bar number entered to the start of the shot, and that is the number that should be entered here. If the shot starts before the bar number that was entered, a negative number should be entered here.

For example, if a shot is recorded at bar 82, but on closer examination it appears that

Shot,1,82,-2,455,1,100

In another example (see example 10 below), a shot is played at the third beat of bar 171. In this case you need to use the tick adjust to indicate that it a full two beats after bar 171. Since one beat is 120 ticks, two beats would be 240 ticks, and it would therefore be entered as such:

Shot,1,171,240,200,1,80

RealDrums Style Example 10

Example 10: Here the shot begins at bar 171 (173-2), at the third beat, or 240 ticks into the bar.

Duration
Unlike patterns, which use numbers of bars for durations, the shots use ticks for durations. So, for example, if a shot lasts for three beats, you would enter 360 (3 beats * 120 ticks per beat).

Here is an example of a shot that lasts for three beats:

Shot,0,83,5,360,1,90

For the best effect, the sound of the shots should decay naturally, and the entire length of the shot including the decay should be entered in the text file. This is especially important when all other instruments are silent, and all you hear is the decaying sound of the drum hit.

Weight
The weight for shots works exactly the same as the weight for patterns, except that there is no need for the use of 0 or 9 weights. This number should be between 1 and 8, with higher numbers representing a greater chance that the shot will be selected each time.

Volume
The volume of the shots is represented by a number between 1 and 127. If 90 is entered, the volume will not be adjusted at all. If a number between 1 and 89 is entered, the volume will be lowered accordingly, and if a number between 91 and 127 is entered, the volume will be raised accordingly. It is generally easiest to test the volume amounts once the style has been completed.
