I have a friend that is an accomplished keyboardist, guitarist and drummer...What he can do with the keyboard to emulate a guitar or drums is unbelievable..The best I have ever heard or seen....He thinks like a guitarist.over laps his hands and picks the correct order of the voicing for strums and voicing of chords..the exact intervals of a guitar...

And he is just as good playing drums on keys...

BTW: he is no slouch on keys either...
