Dorico Template not loading all the VST's

Created a template based on OT’s Beaufort library and saved the combined Endpoints at the bottom of the rack based on the project as seen below.

A new project was completed with the following players

Solo Trumpet. (single player)
Trumpets a3. (section player)
French Horn (single player)
French Horn a4 (section player)
Trombones a3 (section player)
Bass Trombone and Tube (section player)

I made absolutely certain which are section and which are single players–(I’ve been through that problem before). It’s the same as in the template. Alas, when running the template I get this:


The last VST is missing - Bass Trombone and Tuba. Anyone have and idea why the Playback Template doesn’t put the last VST entry in?

Can you share the playback template itself and your example project so we can take a look? Even if we don’t have the VST plug-ins you’re using, we should be able to see something about what assignments Dorico is (or isn’t) trying to make.

Hi Daniel,
Hope you can find something causing this issue. I am rather baffled by this. To save typing in the Players I included an empty project with just the Players so you can run the template against it and quickly test.

In your original score you used to make the template/endpoints, the “Bass Trombone & Tuba” staff is a Bass Trombone renamed. In the “Empty” version, it is a Contrabass Trombone renamed. That would probably be the reason it doesn’t know what to load, it isn’t the same instrument.

If instead of a Contrabass Trombone into the “empty” version, you load up a regular Bass Trombone, it will probably work.

Thank you again, mducharme! I deleted the Bass Trombone & Tuba player and created a new player, this time using the Bass Trombone and indeed this works! Happy again! So Dorico is matching the original players instruments in order to make the template work. It has been rather a mystery to me as to what Dorico was matching up to make the template load correctly. Now I know it is the original player in setup mode. Glad to have that piece of knowledge. One more question: How did you determine that in the “empty” version I had used a Contrabass Trombone instead of a Bass Trombone? I need to to be able to discover this. Thanks again for bailing me out of another mystery.

To do this, you can “Edit Instrument Definition” for the instrument:

In reality you don’t have to change anything in there, but it will show you which instrument definition is used underneath.

When that window opens, you can mouse over the selected instrument definition name on the left hand side and a tooltip appears that shows you the ID code for the instrument. I believe this is the unique ID code that Dorico uses for matching purposes, to make sure it is loading the correct instrument sounds.

I also assume it likely does an “if includes” substring match instead of an “if equal to” exact match as there are some instrument variants that are the same instrument but are different ways of notating it, like there is a “.trebleclef” variant in the case of the bass trombone. Probably they would want to match instrument.brass.trombone.bass and instrument.brass.trombone.bass.trebleclef the same because the clef difference itself would not be enough reason to load a different sound.

(Perhaps Daniel or someone else might chime in here with some of the technical details because I’m a bit curious about this too.)

This is great! So now I know how to check if I’m using the correct instrument. Debugging of non-working templates is going to be a whole lot easier. It’s easy to lose the sense of what the “source” instrument is when they become renamed but if I’d only known how easy it is to find. But now I know. Thanks again for this!
