I would say that, with the current outlook, "NO" - you will most likely never be able to connect your WK-3300 to your iPad. Lack of standardization from brand to brand and model to model has hampered interest in music production apps on the part of Android app writers. There are some offerings, and they are getting better and more numerous, but they still have a long way to go to come abreast of the Apple market. More than a few of the Android tablet manufacturers even have their own sub-versions of the operating system, which further frustrates the situation. App writers don't like having to re-invent the wheel for every different brand/model on the market. It increases the design time and lowers the bottom line. When you buy a Camera Connection Kit for the older iPads or a Lightning cable for the newer units from Apple, you know that, if you connect it to a Class Compliant keyboard, it is going to work. To my knowledge, none of the Android tablet manufacturers make keyboard connection kits. All of the ones I know about are third party units. They appear to be well designed and well made, but due to the lack of hardware standardization on the part of the tablets, the connection kit you buy may not work with your tablet. I have three different Android tables, and each one has its own type of connector for interfacing to the real world. I think my big Samsung is the only one that would work with any of the third party connection kits. If you are interested in this, you should try a search on "music production apps" on the GooglePlay store to see what is available, but better yet, you would probably do better to look into one of the tablets that runs "full" Windows-8 (NOT Windows-RT). They come with standard connectors, have the class compliant USB-MIDI drivers built-in to the OS, but allow installation of aftermarket drivers for non-compliant keyboards just like a regular PC or laptop and run regular Windows software programs. You would be able to connect your WK-3300 or any of the newer units to that.
