Hi, I'm primarily using the PX5S as a controller keyboard for the Yamaha MOXF6. If I transpose the MOXF (using the dedicated transpose buttons - hopefully Casio implement this in their next stage piano/keyboard) this data does not transmit to the PX5S. I need to go in and alter that on the PX5S itself. Anyone any idea on how to send the likes of the transpose data via midi?
