Hey @mark skinner thanks for the nice comments! The keyboard you hear is the midi guitar, it will play any midi plugin - synths, pianos what ever.... I don't play keys at all so I really love the midi guitar.
I had a hard time choosing between AD and EZ but went with EZ3. I really like it, it is quite easy to make a track super quick and very easy to edit the play to what I want, I usually change the kick pattern to suit.
