Hey all, Does anyone know if there is a hardware controller for iPad that will enable me to easily rewind by about 5 seconds for each click? I'm looking for such a device to listen to my lectures which I need to rewind occasionally to catch what my professors say. I guess controllers which require you to hold onto the "previous track" button to rewind would be okay, but inconvenient. The ideal would be a dedicated rewind button that will go back a few seconds in the audio. Thanks in advance!
