There's no such function in Maschine unfortunately, but maybe someone knows of some other way? Maybe apple scripts? Or maybe some software that can read/write both formats?
For example, I have the Arturia V-collection, which is super great. With LOTS of patches. But I would like to have them all in Maschine's library, and be able to search, and preferably have the same tags as in The Laboratory plugin. This is asking a lot, I know, but it would be so great if it worked! And not only Arturia, but all plugins out there! Imagine!
