Descriptions
When you hit a snare drum equipped with an acoustic drum trigger, a sound may be
improperly produced (retriggered) at point A in the following diagram as well, be-
cause the waveform is erratic.
A
This phenomenon is most likely to appear near the point where a waveform fades
away. RetrigCancel detects disorder in the waveform to prevent the retriggering phe-
nomenon.
As the value increases, a sound is less likely to be retriggered but some sounds are
more likely to fail to be produced when you repeatedly hit a drum quickly. Checking
that the sound is not retriggered, specify the smallest possible value.
Configuration of the Mask Time (described below) can also prevent double
reproduction of a sound like this. Mask Time is for ignoring a second trigger
signal within the time defined after reception of the first trigger signal, whereas
RetrigCancel is for detecting attenuation in trigger signal level to determine
whether a trigger signal is something that has been generated with a proper
strike, or is something to be ignored.
Setting the value
While hitting the pad or the like, raise the RetrigCancel value until the retriggering
phenomenon no longer occurs.
A second contact of the beater just after producing a sound, especially with a kick
pad, may cause double triggering. Mask Time functions in preventing this phenom-
enon. A second trigger signal generated within the specified time (from 0 to 256 ms)
is ignored.
As the value increases, some sounds are more likely to fail to be produced when you
quickly and repeatedly strike a kick pad. Specify the smallest possible value.
Mask Time
Ignored
If you hear a sound twice though you have hit a pad or the like only once, adjust
RetrigCancel as described above.
Setting the value
While sounding the kick pad, raise the Mask Time value until bouncing (sound
production caused by a bounce of the beater) no longer occurs.
