Method One:
➀
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)

➂
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.

➃
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.

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.

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.
