Setting Trigger Parameters in a 
Percussion Sound Module
 
Correct trigger type and parameter 
settings provide accurate triggering.
 
We have included an extensive list of percussion 
sound modules with their respective parameter 
settings. Please refer to the charts beginning on 
page 14.
Unlike standard electronic drum pads, mesh or 
rubber, acoustic drums need special attention. 
Please read the following to have a better 
understanding of how various parameters can 
help you get the desired results.
The name of this parameter is self-explanatory, 
and should be adjusted to your playing style. To 
adjust this, play at your lowest dynamic and also 
at your strongest dynamic to make sure you get 
the result you want from your sound module.
Higher sensitivity allows the drum to produce a 
loud volume even when played softly.
Lower sensitivity will keep the drum producing 
a low volume even when played forcefully.
Retriggering happens when you hit the drum 
once, but more than one sound comes from your 
sound module.   Because an acoustic drum 
vibrates in a different way than an electronic 
drum pad, attention is needed here if you find 
this happening. This can also happen from 
vibrations from nearby drums, or even monitor 
speakers.
 
Threshold
 
Threshold level determines the point at which 
the signal from the drum trigger actually 
triggers a sound. You can look at the chart below 
to understand this.
The curves indicate your playing dynamics. In 
this case, no sound is produced a the “A” or “C” 
points, but only the “B” point.
If you set the value higher, then soft hits on the 
drum will NOT trigger a sound. Obviously if the 
value is too low, then retriggering will occur 
easily. In this case, you must set the value 
according to your softest playing dynamics, not 
forgetting about possible vibrations from other 
drums in your kit. 
In a live situation, when playing with a band 
and/or using monitor speakers, this parameter 
may need adjusting according to the acoustic 
environment you are in.
 
Retrigger Cancel
 
Important when you are using drum triggers. Such 
triggers can produce altered waveforms, which 
may also cause inadvertent sounding not only at 
“A” but also at “B” point in the following chart.
Retrigger Cancel detects disruptions in these 
waveforms and makes it more difficult for 
retriggering to occur.
While repeatedly striking the drum, raise the 
Retrigger Cancel value until retriggering no 
longer occur. Set this to the lowest value possible 
while still ensuring there is no retriggering.
Although setting this to a high value prevents
