Donny, when was the last time you sang through a Tyros5, PA4X or Genos. Now, I have now used the Genos, yet, but I will this spring. However, I have used the T5 and PA4X and they sounded and worked as well as any outboard vocal processor I have used. Of course, I don't use midi files, so I cannot attest to that aspect. I can hear quality, and the quality provided by today's arranger keyboard onboard vocal processors is top notch.
