The Lava Genie Sampler Guitar - What is it and how does it/the app work (in 'non-technical' terms!)?

Sorry - I am posting yet another video of the Lava Genie 'Sampler guitar' but, in this one I try to describe 'in layman's terms' what exactly the Lava Genie is, how it and the accompanying app (Lava+) work and, more importantly, why it ISN'T just a digital version of a guitar! Along with the normal (long winded) spiel, I have included a few shots of the Lava+ app (if you want to see the app 'in action' please check out my earlier '2 weeks on and I finally get it' video) and some example clips/songs/pre-sets.
