I'm afraid this is the attitude I have to disagree with. Unless it IS 'barebones', it isn't YOU that is making good music. And, unless your audience is paying you no attention at all, they CAN tell the difference.

Let me ask you a question, Donny. Is it OK for you to lip-synch to someone else's SINGING? Now, the audience MIGHT not notice, and they MIGHT like it even more than your normal voice (if the singer is TOTL) or at least as well!

If 'no body cares!....' to quote you, are you comfortable with this? And if not, why, and what exactly is the difference between doing this and doing the EXACT SAME THING on your keyboard?
