Decay
Note: In this scenario we will use only the snare pad. Depending on the type of pads
being used and your mounting configuration, you may be experiencing some
“double triggering”. If shortly after the initial strike to the snare pad it re-triggers or
sounds a second time, the pad is “double triggering”. This can be controlled by
altering the Decay parameter value.
    
To set the DECAY value:
Press [EXT TRIG] repeatedly until PAGE 2 is selected.
In the bottom left corner of the display, PAGE 2 will have a square around it. There are
three parameters in this page: 
XtalkDec and Nois. The Trigger Number will be selected
(i.e. a circle around the currently selected Trigger Number will be flashing).
Turn the [VALUE] knob to select the desired trigger (snare).
Press [
] twice to select the Dec parameter.
The value beneath it will be flashing.
Turn the [VALUE] knob to gradually increase the value until the snare stops
double triggering on hard hits.
A properly adjusted Decay parameter will end double triggering, and still allow you
to play fast, repetitive hits on the snare pad.
Noise
Note: In this scenario we will be using the tom 1 and the tom 2 pads in a live
performance situation. The two tom pads are mounted together on a single floor
stand, and the Crosstalk and other parameters have already been correctly adjusted.
When you play the pads while no other instruments are being sounded, all of the hits
are triggering and tracking properly.
Now as the band begins and the stage volume is very loud, the stage starts trembling
which causes the drum hardware to vibrate. At times the tom 1 and the tom 2 pad
are triggering when not being played.  This is because the DM5 is interpreting the
signals from the stand vibrations as hits. By adjusting the Noise parameter the DM5
can determine which signals are vibrations caused by the surrounding noise level,
and which signals are actual hits.
    
To set the NOISE value:
Press [EXT TRIG] repeatedly until PAGE 2 is selected.
In the bottom left corner of the display, PAGE 2 will have a square around it. There are
three parameters in this page: 
XtalkDec and Nois. The Trigger Number will be selected
(i.e. a circle around the currently selected Trigger Number will be flashing).
Turn the [VALUE] knob to select the desired trigger (tom 1).
Press [
] three times to select the Nois parameter.
The value beneath it will be flashing.
Turn the [VALUE] knob to increase the value to a level that will stop the pad from
false triggering when the strong vibrations occur.
If the triggering is frequent and strong, try starting with an increase of 20 or more. If the
triggering is not as often and is softer in volume, first try adding 10 to the value, then
gradually add more if necessary.
