- An interactive, clickable layout is included.
- This driver is marked as "not working", due to the lack of audio support. But
the UI is otherwise functional.
- The volume faders can be controlled from the "Sliders" menu.
- The drum keys are mapped to the keyboard in the same. for example:
- The mixer faders can be controlled with the mouse, or from the "Sliders" menu.
- The drum keys are mapped to the keyboard, starting at "Q". Specifically:
Q - Bass 1, W - Snare 1, ...
A - Bass 2, S - Snare 2, ...
Z - Bass 3, X - Snare 3, ...
