Roger,
It is so easy to do yourself. Go into COMPOSER, use DRUM 1 and clear track. Choose STANDARD KIT 1 in PART SETTING. In STEP RECORD click on LENGTH AND use 16th, 16th/3 or 32nd note, depending on how fast of a drum roll you want. It also depends on how fast the song is. A fast song might be better for 16th notes - slow song, 32nd or 32nd/3. Depending on length of drum roll that you want use D1 as the key to play. Keep pressing D1 for the length of drum roll. At the end of the drum roll length press C#1. Volume of D1 for the roll, set VEL (loudness) around 90 to 100 and the crash symbol C#1 to around 120 - 127 VEL then save.
