Hi ,
my PSR1500 is a lousy controller keyboard. You'll have problems with bank changes.

On the other hand my PA800 works well as a controller keyboard.

Do you actually require an "arranger" keyboard, for your purposes ie do you play styles in realtime or are you mainly planning on creating music.

Do you actually need keyboard styles?? or do you create your music from scratch??

Another alternative ( if you use styles, but don't actually play them in realtime )may be something like Band in a Box software http://nn.pgmusic.com/demos/demo_bbw.php

As a soundsource you could use a synthesizer keyboard or software synths.

You may need to give a few more details on what you're actually doing.

best wishes
Rikki
