Did you look at the clip of what I referred to dreamer ? He is playing arranger style on a kuzwiel keyboard. He did not sequenced the entire song from beginning to end. He programmed parts just like an arranger . Then he brought in those style parts as and when he wanted to live and not in a linear sequenced order like a typical sequenced backing track.The point I was making is that it does not matter what the name is on the keyboard . What matters is who is playing the keyboard and what their creativity is . Look at the clip .
