I have kb controller connected by USB and DM48 midi din to GM #1, and both playing same instrument. How do I get DM48 to play a different patch. The GM midi screen on the SD40 shows channel choices, but DM48 will play only on ch 1. It is simple on a keyboard by using different upper numbers. The problem is I don't have room for a big heavy keyboard, and I use the SD40 for a multitude of things. The only thing I have gotten to work is to choose a different instrument when I want to play the DM48 and the left hand sound remains the same. Of coarse, this is the same as changing instruments on the keyboard.
