Dennis, I think we should all appreciate the time PianoManChuck put into making his videos....but I do understand its not that helpful hearing instruments like Bass, Guitar, Synth and strings being played in the same piano style for hearing the quality sounds. I guess until someone else makes demos of the sounds thats all we have to go on...I just took a leap of faith and bought a PX5S after owning a number of flagship synths...it should be here by the end of the week. My guess is the Bass, Guitars, Strings and Brass wont stand up to the quality of the motif/kronos/kurzweil but I hope Im pleasantly surpirised.
