Update:........
I used it last night full bore on a 4 hour gig with the Tyros & give it Two Thumbs Up from me.....for My needs I'll never be tied down to a "On-board" VH unit again using any keyboard, although there is a few models that have quality VH inside......but this versatile little unit is just what the doctor ordered. I recomend it for sure.
Enjoy
