Tremolo - multi note

Hello, a question about the multi note Tremolo in the attached example. There seems to be a slight delay/glitch in playback between each of the 4 tremolo pairs ( am using latest versions of Dorico Pro and Noteperformer for playback). Is there any fix or workaround to get a smoother playback?

Perhaps Dorico is emulating what an actual clarinetist would sound like attempting these tremolos.

It isn’t, rkrentzman, at least not Dorico – at best, NotePerformer.

Although I’m not sure what eboats means when he says “delay” or glitch. It could be very well just artifacts from the interaction between density of attacks and the samples’ attack time.
