knowing that the review process for apps seems to be rather rigid to some extend I would like to ask if there are any special requrements for an app that is targeted to work with certain Midi interfaces only. The particular reason I ask is that this app can not really be tested when not connected to such an interface. Thanks
In the meanwhile I submitted my app and it got rejected in the first phase because I did not include a demo video. So after I created one and put it on YouTube, provided Apple with the link, everything went well.
So as a definite advice not to loose time until Apple comes back after a week or two to just tell you to provide a video - include it right from the beginning....
