If Dorico doesn’t have a definition for a specific percussion instrument that you need, I would suggest repurposing another one and editing its name, which you can do in the Edit Percussion Kit dialog. Make sure you make a note of which instrument you use for which other one, because this is critical to getting playback of the correct sound working.

You’ll need to connect your percussion kit instrument to the appropriate percussion map, which you can create in Play > Percussion Maps and which allows you to specify which instrument and playing technique corresponds to each MIDI note in the percussion kit. I wrote a detailed walkthrough of how this all fits together, which you can read here.

I’m afraid there isn’t, which is a shame, because it would be really useful to us as well! But I asked our sound designers whether they could provide it, and because these sounds came to us many years ago from our colleagues at Yamaha, I’m afraid nobody appears to be able to lay their hands on a precise list of the sounds.
