Dorico, BBC So Discover and percussion

Hello! I loaded for my project a playback template from BBC So Discover. Everything is wonderful except for percussion set. For example the woodblock part plays snare and motst others play bassdrum. How can i change or route it so, that the woodblock part triggers the sample of woodblock in BBC So etc.
Thanks

There’s probably some problem with the percussion map. Are you sure it’s set properly ? You can check that out pressing the cog icon, in the BBCSO Discover area, right panel in Write mode. The channel that should have percussion should have a percussion map along, not an expression map.
