Optimizing the pad settings (Trigger parameters)
The following parameters (Advanced Trigger Parameters) are
automatically set to the most efficient values for each pad when
you select the Trigger Type (p. 46). They don’t require
adjustment, except if you experience any of the problems that
are discussed in the explanation of each parameter.

1. Press [F1]–[F3] to choose the item that you want to
edit.
2. Use CURSOR [
] [
] to chose a parameter.
3. Use [+/-] or [VALUE] to edit the value.
4. Press [EXIT] several times to return to the “DRUM
KIT” screen or just press [KIT].

Trig Type
Scan Time
0–4.0 (ms)
Specifies the detection time for the trigger signal.
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 pro-
duce sound at different volumes. If this occurs, you can adjust the
“Scan Time” so that your way of playing can be detected more pre-
cisely.
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 the

Retrig Cancel

This setting prevents spurious re-triggering.
Important if you are using acoustic drum triggers. Such triggers can
produce altered waveforms, which may also cause inadvertent
sounding at Point A in the following figure (Re-trigger).
This occurs in particular at the decaying edge of the waveform. Re-
trigger Cancel detects such distortion in and prevents re-triggering
from occurring.
While repeatedly striking the pad, raise the “Retrig Cancel” value
until re-triggering no longer occurs.

You can also eliminate this problem of re-triggering 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. Re-trigger Cancel detects the attenuation 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
need not trigger a sound.
