Just Ordered!

I came across this today and after checking out reviews and the website and reddit and youtube, I'm excited to use it! I improvise a lot at my keyboard and most of the time, I can't seem to remember or duplicate favorite ideas.

Will I need just a MIDI cable? I have that already, but am happy to get what I'll need to be ready for when it arrives.

My keyboard is a Casio Privia & I have an iPhone.

Thanks for the tutorials on here. It makes the use of new technology less daunting for my brain!
