I just made a simple test file to listen for the shots and holds: couple bars of rhythm A, 2 bars of C., 2 bars C.., 2 bars C..., then repeat for B style. Mute all but the drums and generate/listen several times. Change style, repeat.
Some VERY different approaches to S&H and volumes. I almost always have to change drum volume for a bar, then reset. Would be nice to be able to do that for the second half individually make the first beat down 2, then back on beat 3... Oh well, 2018...
