Sorry for the same reply, I was occupied this weekend. Yamaha has a "stock" XG set that it includes in most of its synths. Most of the arrangers include additional higher-quality sounds. So the QY does not match the better sounds of the synths. On the other hand, when you play a general-MIDI file or an XG song file, these are the sounds that are used even on the arranger keyboards. Since the MIDI files sound good to me, the QY drums are certainly serviceable. HTH.
