I just figured out how the Master Switches work. So brilliant, wish I had done sooner.
You can use to replace a controller, if you don't want to bring multiple keyboards.
Or, you can use it as a switch to give you more flexibility to add additional sounds to your setup.
Excellent!
Master Switches Topic is solved

Love that feature, too! Feel free to share the joy also in a review in the App Store. Thanks!
