I am trying to understand how drum substitution works. As an example, a line from the a_pgmusic.ds file is:

JAZSIMP.sty=JazzBrushes/4,Jazz/4

What is the relationship between each of these entries and the RD Settings 'Favor Brushes/Sticks' and 'Favor Artists'?

My theory is that the first entry (JazzBrushes) is the default brush kit and (Jazz) the default sticks kit. If the Favor Artist is selected, the '#1' is appended to these.

Am I correct?

Thanks,
R
