Not exactly a love drummer. For for studio work many drumms are compressed. For CD's thes drums save a lot of post production work. The whole keyboard seems to be designed in that regard,

The Korg has many instruments that sound far more in your face live which would have to be tamed in a polished CD again depnding if you you are recording Standards and Pop tunes.

Heavy Rock,,,this is NOT the keyboard. I have not heard a rock guitar chordal progression I would use. I have to pull the Fender off the wall to get those. BUT the leads are great especially if you use the loop inserts to you favorite guiar processor.

The "poppy" example above is at the limit of what I would use asa rhythm guitar.
