The "bread and butter" sounds can be a bit lacking on the PX5S eg., guitars and brass IMO......but it is nice for other sounds outside of standard piano.......

LISTEN HERE

and HERE (6 different demos here - all nice apart from the nylon guitar IMO)

PS: John, good luck with your purchase - surprised you didn't like the key feel of the PX5S. But I'm sure you're very happy with your purchase.

Also, as above, I too would love to see Casio really shake the likes of Yamaha up and get in on the TOTL arranger market. I think they could do it and while they have had some lovely boards out the PX5S really seems to have resonated with buyers and the phrase I have used is "they're doing a Skoda"!!. Interesting times ahead.
