Is there a table that compares TD-12 and TD-20 features?

When I strike the center of the head, I sometimes hear the rim-shot sound also.

Can you show me the pads that are compatible with the TD-series and other sound modules? (2005 Version which includes the TD-12 and VH-11)

What are the main feature differences between the TD-20 and the TD-12?

Is the TD-12 sound module similar in design to the TD-20?

What models of Roland products are compatible with the PDS-15 pad stand and the APC-33 all-purpose clamp?

I can't play open/closed hi-hat techniques with my TD-series sound module. Why is this?

When I strike a pad, a pattern starts playing. How can I stop this from happening?

Is there a feature comparison chart regarding the TD-20X, TDW-20, TD-20 and TD-12?

Can I make a pattern start playing by striking a pad?
