This adapter holds exactly what it promises. This can be a class-compliant USB MIDI device such as the connect (with me running iOS 8.1) and used with compatible apps Novation Launchpad to an iPad.
Caution: Because the launchpad needed (like some USB devices) too much current, there is an error message when it connects directly to these adapters. But with a USB hub with external power supply between all works.
