Chapter 5. Trigger Settings [TRIGGER]
The following parameters (Advanced Trigger Parameters) are
automatically set to the most efficient values for each pad
when you select the Trigger Type (p. 44), and don’t require
adjustment, except if you experience any of the problems that
are discussed in the explanation of each parameter.
1.
Press [TRIGGER] - [F5 (ADVANCE)].
2.
Use [F1]–[F3] and [CURSOR (up/down)] to
select the parameter.
3.
Strike the pad you wish to set.
The setting screen for the struck pad will appear.
You can also select by using [TRIG SELECT].
4.
Use [+/-] or [VALUE] to adjust the setting.
5.
When you’re finished, press [EXIT] to return to
the “DRUM KIT” screen.
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.
fig.ScanTime.e
Scan Time:
0–4.0 (ms)
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 lowest value possible.
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
(
Retrigger
).
fig.Retrigger.e
This occurs in particular at the decaying edge of the
waveform. Retrigger Cancel detects such distortion in and
prevents retriggering from occurring.
Retrig Cancel:
1–16
While repeatedly striking the pad, raise the “Retrig 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 drums
played fast (roll etc.). Set this to the lowest value possible while
still ensuring that there is no retriggering.
