I have edited some perc instruments with custom playing techniques (and note head sets) in Setup mode. Is it possible to migrate them to other projects with the same instruments?
If you bundle them up into a percussion kit, you can then export that kit from the Edit Percussion Kit dialog, and then import that kit into another project: once you’ve imported the kit into the new project, you are free to separate the instruments again and remove them from the kit etc. if you wish.
