I have broken down and purchased the apple lightening connector but now need to also purchase the male USB to male USB cord to try it out. How come with the lightening connection this will work (hopefully)? Want to understand the mechanics of this extra intermediary before sending my husband out on a hunt for it. Also this now adding to cost ($30 for lightening, $30 For USB connector).
Seems that there are still many things to work out when using the iPad as your primary device. Willing to tackle a learning curve but need better directions rather than relying on forum post questions.
So it sounds like your keyboard has both a USB to Device port and a USB to Host port. This can be a bit deceiving. The USB to Device port is shaped just like the USB ports you would find on your computer, which is why your iPhone charger cable fits in it. This port is used for transferring files (like music files, documents, etc.).
The USB to Host port, which is shaped more like a square, is used for transferring MIDI signal between your keyboard and whatever it's connected to. This is the port you'll need to use to allow Playground to know what you're playing.
The cable you'll need to connect your keyboard with the iPad is a USB A to USB B cable like this:

Once you have that, and the adapter that corresponds with your iPad's charging port, then you'll be all set.
