Yes good stuff...I have seen this before...very kool demo.....aside from the great tracking & quality VH you get with this TCHm unit compared to most of the arranger KB on board processors this is a perfect example of why I would never use a headset mic ever again...working the Mic with your head at different angles is imperative to achieving great vocal dynamics when singing. The Harmony M also works better via midi signals with some KB's vs others also which has been my experiences regarding chord tracking. It's not a magic box.....you MUST know how to utilize singing with VH where & when & what type to apply it in a song because inexperience sounds gimicky just as easily through it.
