Apple’s GarageBand website (https://www.apple.com/mac/garageband/) says that new features are coming to the music creation studio. The update will arrive right in time for the debut of Apple Music, Apple’s new streaming music service.
The site says the new features will be available on June 30 in the United States and as “coming soon” in other countries, which is consistent with the Apple Music website. However, Apple doesn’t say what the new features of GarageBand will be.
