Timpani gliss. playback with NPPE

Is there a way to make this work with (at least approximately) correct NotePerformer playback?:

It plays a weird short roll between the notes.

Thank you!

I usually add a pitch bend event to the MIDI in the key editor for glissandos. Not sure if that will work with timpani.

What happens if you select the glissando and set the Playback type property to Continuous?

Then it disappears.
“White notes” gives the best result. Thank you for that idea!
