Advanced Settings for the Trigger Parameters [F3] (ADVNCD)
When you specify the Pad Type (p. 41), the settings in this screen (advanced trigger parameters) will automatically be set to
the values that are most suitable for that type of pad; this means that with the exception of crosstalk cancellation, you will
normally not need to edit these settings.
You should make ne adjustments to these parameters for each pad only if you experience the problems described in the
explanation of each parameter.
1. Press one of the [F1]–[F3] buttons to select the item that you want to edit.
2. Strike a pad to specify the pad whose settings you want to edit.
3. Use the cursor buttons ( / ) to select a parameter.
4. Use the value dial to edit the value.
[F1] (SCAN)
Parameter Value Description
Pad Type Refer to p. 41.
Scan Time 0–4.0 (ms)
Species the detection time for the trigger signal.
Since the rise time of the trigger signal waveform may dier slightly depend-
ing on the characteristics of each pad or acoustic drum trigger (drum pickup),
you may notice that identical hits (velocity) may produce sound at dierent
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,” until the resulting volume stabilizes at the loudest level.
At this setting, try both soft and loud hits, 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 lowest value
possible.
Retrig Cancel 1–16
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 gure (Re-trigger).
This occurs in particular at the decaying edge of the waveform. Retrig
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.
* Although setting this to a high value prevents re-triggering, it then becomes easy for sounds to be omitted
when the drums played fast (roll etc.). Set this to the lowest value possible while still ensuring that there is
no re-triggering.
MEMO
You can also eliminate this problem of re-triggering with the Mask Time setting (p. 44). Mask Time does not
detect trigger signals if they occur within the specied amount of time after the previous trigger signal
was received. Retrig 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.
