Can anyone assist with this conundrum? I have a S900 and a Roland AX-7 Keytar which I want to program so that I can access the the S900's SA guitar and sax sounds remotely...The Keytar just jumps to the GM tones which is very frustrating, The Keytar will not program change to the SA voices only if I change them via the keyboard then the Keytar will play them, whatever I do only the GM voices are selectable from the Keytar...

Any ideas guys..?
