I own a Roland 300GX which has a "Superior Grand" sample which is a different program than the standard GM piano bank. I have recorded the midi track in Sibelius, but when I export it as a midi file and play directly from my Roland, it plays it using the standard GM piano. In Sibelius, I have entered a midi message as text to correspond to the correct program change for the suprior grand, but I still only get GM piano. Is there a different way I should do this>
