Ok.... Preliminary report from me, after using it 30 minutes is WOW!!!!! I hooked it up Easily...set midi channel transmit & other settings on Tyros...setup the Harmony M features to my liking, low/high voices,tone button, and started playing and singing....it really sounds fantastic.I'm using an external pedal for on/off & there is no glitches at all. The voice tracking is perfect & way above the quality of the Tyros VH (which to me is useless)...I'll use it on stage on tonight's gig for a real live checkout and see what happens through my sound system.
But as of now the TC Harmony M is Definitely a KEEPER in my rig!
