If I purchase a single instrument first, and then the collection, can my purchase of the single instrument be applied to the purchase of the collection?

Unfortunately, due to App Store limitations, previously purchased instrument IAPs can not be applied to a purchase of the collection.This is because the Apple App Store does not support bundles for In-App-Purchases, only for Apps
