Sorry for the error in my first message above. I know how to create a pattern but don't know how to put single drum voices, e.g., hi or low woodblock, into the pattern. This for for the XD3 but is probably applicable to other Ketron modules and keyboards as well.
Hope I can get an answer to this. There must be a way because ketron goes to the trouble to assing a single drum voice to each key of the keyboard.
