Parameter Value Explanation
Retrg Cancel 1–16
Detecting trigger signal attenuation (Retrigger Cancel)
When you strike a snare drum etc. to which a commercially available
drum trigger is attached, there might be cases in which the waveform
is misshapen, causing another trigger to unintendedly occur at point
“A” in the following illustration (retriggering).
This occurs in particular at the decaying edge of the waveform.
Retrigger Cancel detects such distortion and prevents retriggering
from occurring.
While repeatedly striking the pad, raise the “Retrigger Cancel” value until retriggering no longer
occurs.
Although setting this to a high value prevents retriggering, it then becomes easy for sounds to be
omitted when the pad is repeatedly struck quickly. Set this to the lowest value possible while still
ensuring that there is no retriggering.
MEMO
You can also eliminate this problem of retriggering with the Mask Time setting. Mask Time does
not detect trigger signals if they occur within the specified amount of time after the previous
trigger signal was received. Retrigger Cancel detects the decay of the trigger signal level, and
triggers the sound after internally determining which trigger signals were actually generated
when the head was struck, while weeding out the other false trigger signals that should not
trigger a sound.
XtlkCancel 0–80
If more than one pad (or acoustic drum to which a drum trigger is attached) is mounted on the same
stand, you can use this setting to prevent the vibrations caused by striking a pad from producing
unintentional triggering (crosstalk) for a different pad (or drum trigger). For example, if pad B
unintendedly sounds when you strike pad A, increase the XtlkCancel value of pad B until crosstalk no
longer occurs. If this value is raised excessively, the sound of pad B will tend to drop out when pad A
and pad B are struck simultaneously.
ScanTime 0–4.0 ms
Trigger signal detection time (Scan Time)
Since the rise time of the trigger signal waveform may differ slightly
depending on the characteristics of each pad or acoustic drum trigger
(drum pickup), you may notice that identical hits (velocity) may produce
sound at different volumes. If this occurs, you can adjust the “Scan Time”
so that your way of playing can be detected more precisely.
While repeatedly hitting the pad at a constant force, gradually raise the Scan Time value from 0 msec,
until the resulting volume stabilizes at the loudest level. At this setting, try both soft and loud strikes,
and make sure that the volume changes appropriately.
* As the value is set higher, the time it takes for the sound to be played increases. Set this to as low
as possible.
MaskTime 0–64 ms
Double triggering prevention (Mask Time)
When playing a kick trigger, the beater can bounce back and hit
the head a second time immediately after the intended note—
with acoustic drums sometimes the beater stays against the
head—this causes a single hit to “double trigger” (two sounds
instead of one). The Mask Time setting helps to prevent this. Once
a pad is hit, any additional trigger signals occurring within the
specified Mask Time are ignored.
Adjust the Mask Time value while playing the pad.
When using a kick trigger, try to let the beater bounce back and hit the head very quickly, then raise
the “Mask Time” value until there are no more sounds made by the beater rebound.
Increasing this value makes it more likely that a note played in rapid succession will drop out. Set this
to as low a value as possible.
MEMO
If two or more sounds are being produced when you strike the head just once, adjust Retrigger
Cancel.
