Thanks for your response UD... i now use the PA60 through a dedicated amp, sounds much better and more balanced... As for the tone controls, i am surprised that there isnt any sort of EQ control, though i remember the I30 not having any either... it does make a difference, especially at moderate levels without cranking it up too much.. the X1 for example sound excellent at a moderate level with the EQ right up, but as soon as you pass half way, the speakers struggle... but most of the time i dont use it that loud, so tone controls does help...

As for the other problem, im not sure what else to do. WIth the same midi files that i play in the X1, i am able to change the tracks as i wish.. in fact, there isnt one midi file or song that wont allow me to edit in the X1 where as there are quite a few on the PA60 (and if im not mistaken, when I used the GEM WK8 it was the same, some tracks wont allow me to change the volume or voice)...
