Some companies make pads which have what is known as a "rim switch" trigger.
The idea is that it enables the drummer to grab the rim of the pad and "choke"
whatever sound is playing (typically a Crash cymbal). Some examples of such a type
of pad are the Yamaha PCY80S and the Roland PD-9.
These aren't really considered "dual-zone" pads because you can't really "play" the
second trigger with a stick. But it is possible to have the rimswitch trigger play a
Drum in the DM Pro. Refer to "Chapter 7: Triggers" and look up the paragraph
entitled "P12 The AUX TRIGGER NOTE SELECT Function" on page 116 for
information on how to do this. Of course, you have to set the AUX Pedal Type to
Switch first before the DM Pro will allow you to do any of this. But in effect, the AUX
Trigger Input becomes "Trigger 17" when you use it this way.
In order to choke off a Drum with the AUX Pedal Input, both must be assigned to the
same Mute Group number. For a description on what this means and how to do it,
refer to that section in "Chapter 4: Programming Drumkits."
Although the typical use of such a pad is for choking off a Cymbal, there are
certainly lots of other potential applications. The sky is the limit! Try it for muting
Snare rolls, Sound effects, or Drum loops you've burned to a Flash RAM card using
Sound Bridge.

RO EFERENCE
The diagram shows the mono end of the TRS cable which is marked
"TIP" being plugged into TRS Trigger Input 7/8. Ideally, a mono pad
would be plugged into one of the mono Trigger Input jacks (1, 4, 5,
or 6). That way you don't "lose" a Trigger by plugging a mono plug
into a TRS (stereo) jack. But if you want, you can plug the cable in
this diagram into any one of the Trigger Inputs from 1 to 14. Once
you have, plug the other mono end (the one marked "RING") into
the AUX Pedal Input jack.
