sounds according to the instruments

Writing for percussions, I selected “Temple Blocks” in non chromatic percussion. I have a 5 lines score but , I can only hear two different sounds, one “high” on the upper 3, and one “low” in the two remaining lines. How could I have a sound that matches the graphical outlook?

Yes, I’m afraid there is no designated temple blocks patch in the sounds that come with Dorico, so only two different pitches are available in the default sounds.
