I don't know what you mean with that question. I can give an example of my problem. For example, I have a VDL hi hat. I enter open hi hat notes, when it plays back, they are closed. How do I fix this problem? I have to send this music in on Sunday and am very scared I will not finish it now with this problem. In my playback, the 7.0 soundset is there. Mallet and battery instruments work. Bass drum, tam tam, drum set, etc do not work. What am I doing wrong here?
