I’m just getting near to the end of a task of trying to import a dozen various old MusicXML files with different orchestrations and different instrument names at times to create a single project. It has been somewhat frustrating to say the least. Dorico offers the feature to “Create All New Players” or to “Merge with Existing Players Where Possible”. If you choose the latter then an entirely new orchestra is chosen with all the instrument names duplicated which is fine is you really do have different instruments. However, Dorico only seems able to merge if the names are identical. There is no way than I can see that you can tell Dorico that a Horn is the same as a Horn in F which is the same as a French Horn and/or French Horn in F.
Is there some clever way to reduce the workload here? What I feel is required is at the import stage is an extra dialog giving the possibility of getting Dorico to treat instruments which actually are the same as the same once Dorico has analysed the MusicXML file and could present for instance a list of clearly related instruments for confirmation or otherwise.
