A possible mod to add dynamics: shape the rear part of the "stick", the one being hit by the programmable pins, so that by inserting or extracting the pins from the rolling cylinder, the sticks can be raised to different extent emulating the hitting of a drum with different force when they're released. Dynamics makes a huge difference in making electronic drums sound more natural.
