Clif, not to mislead you, It's been about a year since I sold my VA7..As I can recall we are able to trigger our own vocals for back up spots in realtime[instead of harmonizer], since the new upgrades I believe we can use the Variphrase in the arranger parts now[original models could not]. I have been considering the VA76 again because of this ability.Hesitating till word on a new model[???]
