Actually I find my PSR740 quite an expressive instrument. I miss the feature that I had on the PSR730 which allowed me to map the modulation wheel to the filters, this offered useful control over dynamics. I believe its possible though with the expression pedal. I do though miss portamento, the monophonic type that allows one key to be held and another to be pressed so that the pitch bends up or down without the attack phase. In terms of expressive sounds, an expression pedal takes a bit of getting use to. Careful use of dual voices (in the case of the 740 or triple on the 8000/9000) can produce some nice results, especially with XG technology - but perhaps a breath controller adapted to fit the expression pedal input would be the best idea? The DSP's can also help out, again using the registration memories helps to make the changes in performance. Try changing the modulation wheel to other functions such as volume control or brightness, or even altering the level of voice R2 (or R3) - the same can be achieved with the foot pedal.
