Playing technique duration

I’m trying to set up an expression map for Timpani with BBC Symphony Orchestra. I am using two kinds of beaters in the playing techniques:

“puffy (beater)”


“rods (beater)”

The puffy (beater) works as expected, but for some reason “rods (beater)” applies only to the note it is attached. After that, it switches back to natural.

Is there way to control this behaviour? I would think that it would be the “has no duration” box, but that doesn’t affect the playback for me.

Check that the playback playing technique for “Rods (beater)” is set to be a Direction rather than an Attribute in the Edit Playback Playing Techniques dialog.
