Impaktor is one of my favorite iPad instruments! From the look and feel of the interface to the quality of sound output to the fast response from the developers...this is a fantastic value for the buck!
I had an issue with the mic after the iOS 7 update. Access to the mic became disabled for Impaktor after the upgrade, but was easily remedied in the iPad settings. All is right in the world.
