I find this thread to be the essence of arranger keyboards. I've had very limited exposure to a variety of manufacturers arranger keyboards, but it seems to me
manufacturers have not drilled this vein much deeper.

Imagine if some keyboard manufacturer would put something like "Band in a Box" with expandable 1000's of templates into an arranger so that you can synthesize a style by taking 1000's of small midi clips of drum tracks, bass riffs, left hand riffs, strings etc. and morph them into any beat and tempo and assemble them into a brand new style quickly and easily!!!

This to me would be a HUGE incentive for purchasing a new arranger.

I don't use UD's method of 10 simple styles for all my songs, but instead try to get as close to the original song as possible. In this regard I find arranger keyboards very frustrating when I cannot find the style that is the most appropriate for a given song.

The other point here is that, if you use the same few styles, you get that cheezy "Oompa" scenario going. With a creative style maker in the arranger, you can create endless flavors of styles to keep things fresh and interesting.

Anyone else feel this way?
