I'm also using a laptop in my number, specialy during long parties. I use it in Uncle Dave's "functional" sense, mainly to store and play MP3 or WMA. I have several playlists of songs ready for several ocasions, and use them when I'm resting, or when I'm in a mood to dance along with the crowd! :-)

Uncle Dave, I suppose you make use of the PSR2k internal sounds by utilizing the MIDI IN device of your laptop connected to MIDI OUT of the keyboard. Am I right?
