>> If you are playing a song with a tempo in between the tempos of the Real Drum .wav files how do you tell which .wav file BIAB is using??

The name is written in the top title bar.

>>> Also, does anyone know if it is OK to put a semicolon (;) in front of a pattern so that BIAB won't play that pattern?

Yes.

Another approach is to write a line like this

BarsBlocked=23,45
; the bars blocked will prevent any pattern with those bar numbers from playing in the style
; these bar numbers are numbers in the realdrums wav file

for example, for the BossaBrushes style

c:\bb\drums\BossaBrushes_100_Style.wma is the WAV file
c:\bb\drums\BossaBrushes_100_Style.txt is the txt file that you put the line BarsBlocked=23,45
To determine bar numbers, load the wma file into BB and play it. Note that the bar numbers start at -1 (first 2 bars are a countin).

Have Fun!
