If a pad or drum “double triggers” when it is struck, it may be necessary to adjust the
Decay level. This is evident when shortly after the initial strike to a pad, a second
trigger from the same pad is generated, or it “double triggers”. Note: With certain
pads it may not be necessary to adjust this parameter.
With the Dec parameter selected (flashing), turn the [VALUE] knob to select the
desired level of decay suppression necessary to stop the pad from double triggering
(00 is minimum, 99 maximum). This level will depend on your current set up,
including the mounting configurations and the type of pads used.
When triggering from acoustic drums, the factors involved are staggering. Not only
do the type and size of drum make a big difference. Whether the drum is single or
double headed, the tension of the head(s), the muffling, and the trigger placement all
play very important roles in getting good results and proper “tracking” of your play.
For more detailed tips and suggestions in these areas please refer to Tips On
Triggering From Acoustic Drums, on page 49.

OISE
When in a high Noise floor level situation such as playing live on a stage with bass
cabinets nearby, it may be necessary to adjust the Noise parameter level.
With the Nois parameter selected (flashing), turn the [VALUE] knob to select the
desired level of suppression necessary to stop the pad from false triggering (00 is
minimum, 99 maximum). Stage Noise and rumble, the stability of drum risers and
platforms, volume, and crowd vibrations are all factors in choosing the proper level.
Remember: In keeping potential problems to a minimum, it is a good idea to try to
keep some distance between your pad or drum kit, and nearby speaker cabinets
(especially bass cabinets). Whenever possible, try to aim them so they are not facing
directly towards your set up. Also, avoid unsteady drum risers and hardware.

OOTSWITCH

ODE
There are two footswitch options, Hi Hat Pedal (which lets a footswitch act like a hi
hat pedal) and Drum Set Advance (pressing the footswitch increments the Drum Set
to the next higher number; past 20, it wraps around to 00 again).
You can use either a normally closed or normally open momentary contact
footswitch. Plug it in to the rear panel [FOOTSWITCH] jack before powering up the
DM5; on power up, it will automatically sense the footswitch polarity and calibrate
itself accordingly. If your footswitch seems to respond “backwards,” make sure the
footswitch plug is fully inserted into the footswitch jack, then turn power off and on.
Press the [EXT TRIG] button repeatedly until page 3 is selected.
Use the [VALUE] knob to select the desired Footswitch function (HAt or Adv).
Two additional parameters (located in pages 4 and 5) are used when the Footswitch
Mode is set to HAt. Ext Trig page 4 shows the MIDI note number that the footswitch
will trigger when it is pressed. Page 5 shows the MIDI note number that Trigger
Input #1 will play when that pad is hit while the footswitch is held closed.
