These Cubase Mixer maps are for editing and remote parameter changing with the Alesis D4 & DM5 Drum Modules.
The operation of these mixers is a little bit unusual. You must first click on the "edit enable" button. You then choose the parameter you want to edit, and use the data slider or the up/down buttons to adjust the chosen parameter. When you have finished, click the edit disable button.
