Just guessing, but I’d check that you also made the stave endpoint connect to the proper VST Instrument plugin. It does sound like it’s still pointing to Note Performer.
You’d check this in the Play Tab. Click the Instrument track/stave you want using the alternative sample library. Click the “Track Inspector” tab. Make sure in the “Routing” tab, that the Plugin AND the channel is correct.
I.E. Here I have the Piccolo track highlighted. I can see in the Track Inspector that it is routed to an instance of Bidule/ARIA that I’ve setup in my playback templates to be named COMB2 Piccolo. It also transmits over Port 1, and Channel 2. In this case I have 4 soloists loaded in odd channels 1, 3, 5, 7, and 4 tutti sections loaded in even channels 2, 4, 6, 8. This particular arrangement only needs one tutti section tho’ and it’ll use channel 2.
I can also click the cog in the Routing tab to make sure it uses the expression map I need involved. In this case the default Modulation Wheel Dynamics map is fine for the library/situation.
This particular plugin (Bidule hosting ARIA) also spans 16 faders on the Dorico mixer by default. I’ll only be using 4 of them for my piccolo sections, so I can limit it to 4 stereo channels here as well.
Since I’ll be using this Piccolo section in future projects, I can also 'Save Endpoint Configuration" from here. Later I can use that configuration to design my own custom Playback Templates.
And here’s a quick glance at a wind band template I’ve made for the Garritan Concert and Marching Band library. If I know I’ll be working with a wind band score, I can chose this template and Dorico will do his best to use my favorite sounds. If it can’t find them, It’ll revert to the closest match it can find with HSO and/or HSSE content.
Extra info on building complex instrument templates…
This particular score doesn’t call for everything my COMB2 template supports. I built it to provide two to four soloists and two to four tutti sections for each instrument family. When I built the template I made a huge empty score with staves pointing to all the instances/channels I might need first. Saved the Endpoint Configurations, and now the template can support pretty lush arrangements with many different parts.
It’s possible to build up your templates a little at a time too. You can ‘overwrite’ endpoint configurations with newer versions as they ‘grow’ to support larger scores. I did find that things are more consistent and predictable if I go ahead and load up a huge empty score template and set things up there first tho’.
