Keyswitch alternatives in percussion maps

Could someone with more experience let me know if it’s possible to make a percussion map in Dorico which would allow access to all these sounds:

My attempt only ever results in 1 tam-tam (with KS 24) sounding

I think in principle this could be done, but you will mainly be stymied by the fact that you need multiple gong instruments representing the different sizes: you won’t be able to access all the sounds from a single gong instrument, because all of the techniques are the same, but the actual gong is different. Currently you can’t define your own instrument type, so you can’t define gongs of different sizes.

Ah, OK, thanks Daniel! For now I’ll try to work around it.
