First, attach an inexpensive contact transducer to the center of the drum stand and plug it into a DM5 input. . Next, go to Ext Trig page 1 and select the Velocity Curve setting of 0 (Unassigned) for this trigger. . Go to the next page and set the Xtalk, Decay and the Noise levels all to 00. This low level will allow the maximum amount of Noise and stand vibrations to be detected by the DM5. . Using the TRIG LEVEL meter (at the bottom of the display), adjust the level to select a “hotter” than usual Gain setting. Since in this case the gain is effected only by the stand vibrations, a very strong signal is needed to maximize the trigger's performance. . Now as the stage vibrates, or when other signals trigger the drum stand transducer, the suppression function will note this signal and determine that any softer signals coming from the other three pads must be crosstalk. Also, if the suppression function sees a soft signal from the three main pads but little or no signal from the drum stand transducer, it will assume that the pad signals are valid hits and trigger the DM5 sounds. Method Two: In severe cases, this is another way in which the Unassigned feature can be used. For this scenario lets use the bass as the reason the surrounding Noise level is making proper triggering difficult. Each time the bass player “pops” a string, the vibration triggers the tom 1 pad. . First, take a direct out from the bass amplifier, and plug it into an unused trigger input on the DM5. . Next, go to Ext Trig page 1 and select the Velocity Curve setting of 0 (Unassigned) for this trigger. . Go to page 2 and set the Xtalk, Decay and Noise levels all to 00. This low level will allow the maximum signal to be detected by the DM5. . Using the TRIG LEVEL bar graph meter, adjust the level according to the severity of the false triggering. If notes are constantly triggering, use a high gain. If only occasional, select a lower level. . Now when the DM5 receives a signal (from the tom 1 pad) which was generated by the string pop from the bass, not only will it compare this signal to the other drum pads, it will also compare it to the bass. In essence, the DM5 isolates the bass from the Noise floor and “thinks” the bass is a another drum pad. It will now treat it the same as any other pad and “filter” out the unwanted signals. DM5 Reference Manual Chapter 6: External Triggering Note: Note Chase will not follow any trigger that has been set to Unassigned. To view an Unassigned trigger’s VU-style bar graph meter in order to adjust gain (page 44), use the [VALUE] knob to select the corresponding trigger input (page 43). CROSSTALK If several pads are mounted on one stand or rack it is possible to experience interaction or “crosstalk” problems. Adjustment of the Xtalk parameter makes it possible to resolve these problems. Note: In configurations where some pads are individually mounted, the default setting of 30 may be sufficient, making it unnecessary to adjust this parameter. In that case, skip this section and go on to the next section, “Decay”. With the Xtalk parameter selected (flashing), turn the [VALUE] knob to select the desired level of crosstalk suppression necessary to stop the problem pad from triggering (00 is minimum, 99 maximum). This level will depend entirely on your current pad or drum configuration. Remember: When experiencing an interaction problem, the trigger that needs adjustment is the pad that is false triggering, not the pad being struck. One easy way to remedy an interaction problem is to “silence” the pad(s) which are not “false triggering”. Example: Suppose you hit the snare pad and the tom 1 pad triggers. . First, press [MIX] and reduce the volume of the snare pad to 00. Now when you hit the snare pad you won’t hear it, but you’ll hear the tom 1 pad false triggering. . Next, press the [EXT TRIG] button twice (which gets you to the Xtalk parameter on page 2) and select the tom 1 trigger to edit. . Press the [ ] button once to select the Xtalk parameter. While you hit the snare pad (false triggering the tom pad) gradually raise the crosstalk level of the tom 1 pad. Continue to raise the level until the tom pad stops triggering when you apply hard hits to the snare pad. By using this technique, you have isolated the problem drum, and made it easy to “dial in” the proper Xtalk value without the sound from the other drum becoming distracting or confusing. . Finally, press [MIX] again and reset the volume of the snare pad to it’s original level. Note: Always increase the Xtalk value in small amounts for two reasons. The values are very sensitive, so an increase of as little as 2 or 3 can make a difference in suppression. Also, an unnecessarily high Xtalk setting actually suppresses the sensitivity of the trigger input, resulting in the occasional loss of softer hits. If a situation where a high Xtalk setting is necessary to stop false triggering, but pad sensitivity loss is noticeable, try this combination. Start by sl...
