or, here's another trick muso made me think of -
If you really want to get precise, many of the RDs have each drum recorded by itself at the end of the file.
In Realband, these can be Cut/Pasted anywhere on any track, or used as 'samples' in a VSTi sample player.

On these tracks the sky is the limit. Create whatever drum pattern you want. <grin>
I've only toyed with this for testing, as there is usually a RD track/variation that gets close enough, or gets used early enough to serve the purpose.

It's a different workflow (not done from the Chords window for example)

Make your sound your own!
.. I do not work here, but the benefits are still awesome
