You know, I've heard of EWI's, but I've never actually seen/played one, have you? I didn't realize that you played the melodica. Any tips? As for your question about playing it like a keyboard or horn, I think the answer is both. I will hold down a chord and let the breath do the work and then I'll also hold down the breath and let the keys do the work. But the use of breath really allows you to give it some emotion. It's a pretty simple little line at the end of this recording, but if I were to play those notes on a synth it wouldn't be nearly as "emotionally charged" -if it is at all. You can tell it's being pushed out by something and that makes a difference imo. I'm sort of captivated by this little instrument. Can't believe I waited this long to get one.
