5.5 TRIGGER DCAY CONTROL SELECTION
If a pad or drum "double triggers" when it is struck, it may be necessary to adjust the
DCAY 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. In that
case, skip this section and go on to 5.6 Noise Control Selection).
1. After selecting the desired Trigger whose decay level needs to be set, place the
cursor under the DCAY parameter. Example:
TRIG:03 XTALK:30
DCAY:10 NOISE:00
2. Turn the Data wheel 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, but things such as; if 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 External Triggering From Acoustic Drums, included in the
D4 literature package.
5.6 TRIGGER NOISE LEVEL SELECTION
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. If your
situation does not necessitate the need to make these type of adjustments, skip this
section and go on to 5.7 Trigger Gain Selection.
1. After selecting the desired Trigger whose noise level needs to be set, place the
cursor under the NOISE parameter. Example:
TRIG:03 XTALK:30
DCAY:10 NOISE:00
2. Turn the Data wheel 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.
