SYSTEM
Parameter Value Explanation
Scan Time
0–4.0ms
Trigger signal detection time
Since the rise time of the trigger signal waveform may dier 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 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 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.
Mask Time
0–64ms
Double triggering prevention
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 has been hit, any additional trigger signals occurring
within the specied “Mask Time” will be 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, then adjust Retrigger Cancel.
Retrigger Cancel
1–16
Detecting trigger signal attenuation
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 in 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
drums played fast (roll etc.). 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 specied amount of time after the previous trigger signal was received. Retrigger
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.
Position Head *1
OFF, ON
Turns head strike position detection on/o
If strike position detection is on, nuances of the strike position on the head will vary the tone.
Position Rim *1
OFF, ON
Turns rim strike position detection on/o
If strike position detection is on, nuances of the rim shot will vary the tone.
XStick Threshold *1
0–127
For a pad that is connected to a TRIGGER IN jack, this species the force at which to switch between the cross stick
sound and open rim shot sound.
Setting this to a higher value makes it easier to get cross stick sounds. When
set to “0,” playing a cross stick produces the open rim shot sound.
For a digitally connected pad that allows cross stick technique, playing a cross
stick with a strike that is stronger than the value of this setting produces the
open rim shot sound.
* For a pad that is connected to a TRIGGER IN jack, be aware that if this value
is raised excessively, the cross stick sound will also be heard when you play
an open rim shot.
ExtNoiseCancel
OFF, 1–5
This setting lets you prevent a drum from being triggered unwantedly by a strike on a drum to which no drum trigger
is attached, or by sound or vibration from the surroundings (noise cancellation).
This noise cancel function can be used if you use a stereo cable to connect an “RT-30K” or “RT-30HR” drum trigger to
the following TRIGGER IN jacks and specify the Trig Type.
Supported TRIGGER IN jacks
5 SNARE
5 TOM1–3
5 AUX1–3
* The “RT-30H” does not support the noise cancel function.
*1: For some Trig Type settings, this cannot be specied.
* The following parameters do not return to their default values when you change the Trig Type or press the [F5] (DEFAULT) button.
