Some Native Instruments products, like KOMPLETE bundles, are available as a download version or a product box. Additionally, all hardware products (MASCHINE MK3, KOMPLETE KONTROL keyboard, etc.) come with accompanying software bundles like KOMPLETE Select.
If you order a software bundle as a product box or a hardware / software bundle, you have to wait for the shipment to arrive in order to activate the software. The package includes the serial number you need for the activation.
