if you're working in Real Band, you can also go to ACTION/DRUM GRID EDITOR
and use the editor to create whatever snare pattern you want.


You can also create and save other patterns, then insert your saved patterns into other songs with the menu selection: EDIT/ FILL TRACK WITH MIDI DRUM PATTERN

There are a bunch of presets already, but if you saved your original pattern in the same directory, it should show up in the list of available patterns

(this also works when you need more cow bell)
