I have a few things to say about the app. It looks cool and sounds amazing. I found UI a bit confusing and if it was up to me I would have designed it completely differently. But good news is that I got used to it quite quickly. I like seeing big players making cool iOS music apps. iMaschine is definetely a step in a right direction. I would welcome an iPad version. All NI developers have to do is create an iPad UI for it, the sound engine stays the same. It comes down to whether Native Instruments wants to do that or not.
