I am a new synth user who just got a used Korg X3. The Program mode seems to work fine. According to the manual, to select Combination mode you press the Combi button. After doing this I get no sounds when I press the keys. Am I skipping a step? Is there some Global setting that would affect only the Combination mode to say, mute the sound, or separate the keyboard as a controller from the internal synth? Thanx, John

John, please see my response in Korg Discussion. --Barry
