I don’t ever recall anyone saying, “Hey, you’re faking it, or you’re not really playing.” It’s more like I heard yesterday, “Where’s all those sounds coming from? How’d you do that”? I generally take the time to show them and provide a short demonstration. Most folks I know love the technology that’s been brought to musicians. Some of my closest friends are Ph. D’s in music (not me) and they are wow’d by what one person can sound like.
