A question for fellow Mediastation owners. I'm exploring COMBI mode and I've come up against something I cannot figure out.

In COMBI when you put say... Strings on the left transposed +12 and and a Trumpet on the right ( all giga sounds). When you save and exit back to the main screen the keyboard faults to two piano sounds, one for the left transposed +12 and one for the right.

Why ?

I have to press the save button again or jump to another mode and back again just to hear the COMBI sound I made working normally but this does not solve the problem permanently. Changing to another combi and bank again, chances are it will default back to the piano sounds.

Yet the few sounds that were in COMBI mode already work normally.

So why don't my sounds work all the time ?
