Dear Don,
Try Q8BEAT1 on the Keyboard, it fits in very well with "POWER OF LOVE", originally sung by Jennifer Rush, I like the powerful drum beat on this style, try all the variations, number 3 has a very full sound. I have found these styles untilise the DSP to great effect, so hearing them on your computer will definately not give you a good impression.
Also I like playing big band music, I have found applying "ambience" DSP to the big band styles gives a very authentic live effect.
Note to DNJ, you mention you found the PSR9000 speakers very poor, if you are talking about overall volume then I had the some impression to start with, then I realised all the individual section volumes, including style, are factory set at just over half volume, turn these up and the keyboard has more than enough volume capacity for home playing/ small hall.
Also, I have edited one of the Bass/Chord hold styles to incorporate "live strings" in the bass, have put "live" strings" in the left, choir/church or strings in the right, play some large chords with both hands, the sound is monumental, the depth of bass is incredible, try it. I have yet to find a keyboard that can provide this depth and volume of sound through it's own speakers.
Paul.
