EXIERNAL 7RIOOER.
QUIGK
The D4 has twelve trigger inputs designed to accommodate the most widely used drum pads and other triggering sources. It's triggering mechanism is an advanced signal to midi converter which incorporates five user controllable parameters. Trigger parameters are independent for each of the twelve inputs, and the set up is global for all drumsets.
The five types of user controlled parameters are:
1.VCURVE. There are eight separate curve tables, 0 through 7 which represent the velocity curve, or sensitivity of the trigger
input. Curves
2.XTALK. The crosstalk parameter is the trigger suppression level adjustment. It is used to control interaction problems between pads or drums. Crosstalk problems can occur when two or more pads are mounted on a single stand or rack.
3.DCAY. This represents the signal decay time and threshold of the D4'strigger inputs. In other words, DCAY controls the amount of time between once a pad has been struck and
triggers, to when it will trigger again from another hit. When properly adjusted, this parameter defeats "double triggering " by allowing the D4 to determine which signals are actual hits, and which are secondary decay signals.
4.NOISE. The NOISE parameter allows you to control the noise floor, or the signal level threshold that an exterior vibration or sound must exceed before it will trigger a drum
sound. This is used mostly in situations where the stage volume and vibrations are strong enough to "rattle" the drum hardware to such a point that the D4 "thinks" these vibrations are actual hits.
5.GAIN. This is the signal strength that the transducer is sending to the triggers in the D4, It'sadjustment is very similar to that of a tape recorder'sVU meter. With the gain threshold set too low, soft hits may never be recognized.
