Usually I write some pithy blog about how to do something awesome in Mainstage, but today I decided to give you something free instead: my custom built Mainstage 3 template for writing out the Nashville Numbers system.
Here's how it works:
1. Open your template, then click on one of the folders in the template.
2. When you're writing out your Nashville Numbers chart, make sure you've selected the actual song folder itself, otherwise your chart will disappear when you switch patches.
