I use the Composer for about 99% of my recordings - it's one of the most valuable parts of the KN7000. It allows me to produce much more authentic backings for my sequences, rather than the constantly repeating 4 measures within built-in or 'normal' styles. I also use it for live playing when backing a vocalist. The great thing about it is that you can include these little 'figures' and nuances which help to make a song/tune more authentic and each of the 4 variations can be up to 16 measures long. The 'Fill-Ins', Intros and Endings, can also be up to 16 measures.....
