Virtual Drumline VDL Template

I have viewed the "Dorico Marching Band Drum Mapping for VDL and downloaded the files. When I click on the VDL template 20-06-29.dorico file I get the following message:

This project references a Playback Template playback.user.vdl_hssehso_pro that is not installed on this system.

The other file in the downloads is VDL & NotePerformer.dorico_pt. Is this the file Dorico is looking for, and if so, how do I install it for use?

Welcome to the forum, jrunge. To install the .dorico_pt file, simply drag it onto the Dorico window, and it will be installed. You should then see new playback templates in the Play > Playback Template dialog.
