have a look at this you tube clip of the Korg M50 using 'templates' to write songs.

What struck me is that i could reproduce what the demonstrator did in half the time using the PA1X by simply using an existing style drum pattern, muting the other voices and then over dubbing my own original chords , instruments etc either using the style to get the chord structure of the song done or simply using the drum track and then recording all the other parts myself. This is precisely why the youthfull arranger market is ripe , all that needs to be done is to show the complete flexibility of a totl arranger like the Korg range.

anyway here the clip
