(: Is a common mistake is a mistake in the 'in' to 'to' put Caution) and then plugged into a USB port to plug 'in' at the 'OUT' of the keyboard plugged in. As 'Garage Band' was started, I could losklimpern directly. Problems with latency I could not detect, can not tell the difference at a Tascam US-144, which I can now finally inserting elsewhere without ever umstöpseln.
Highly Recommended!
PS: Also runs without problems when it is connected to an Apple USB keyboard.

Addendum:
When writing this review, I had the Adapter for almost 4 months of use.
