Hm. Sounds and looks to me like it was all faked. But if not - well done.
I must admit, I'm a bit suspicious too. But in a friendly way, cause if it's not, then that's fantastic!
But considering carrots are all about the same size, how did you get the pan pipe carrots and the slide carrot to by such different pitches? And also, how did you manage to get NO glissandos with a slide carrot? I could never even do that on a trombone, much less a vegetable!
