When you turn the thing on the first time, drums should sound like drums, highs and lows shouldn't need much adjustment. Effects should be set at least in the ballpark. You shouldn't have to load piano samples, or any other samples, for the thing to sound like the instruments you are emulating. If it has vocal harmonizing, it should have some presets that sound pretty much like someone singing harmony with you, and shouldn't need a lot of editing. Is that asking too much?
