*3 This cannot be specified if Input Type is "PADx2. "

Value Explanation
This is the same parameter as Input Type (p. 21) in the BANK.
This is the same parameter as Trig Type (p. 21) in the BANK.
Trigger signal detection time
Since the rise time of the trigger signal waveform may differ slightly
depending on the characteristics of each drum trigger 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.
0–4.0ms
While repeatedly hitting the drum trigger 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.
Detecting trigger signal attenuation
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).
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 drum trigger, raise the "Retrig Cancel" value
until retriggering no longer occurs.
1–16
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 specified 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.
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 drum trigger
has been hit, any additional trigger signals occurring within the
0–64ms specified "Mask Time" will be ignored.
Adjust the "Mask Time" value while playing the drum trigger. 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.
MEMO
If two or more sounds are being produced when you strike the head just once, then adjust Retrig Cancel.
Adjusts the balance between the force of striking the rim or edge and the loudness of the sound.
0–3.2
If you increase this value, even soft strikes on the rim are sounded at high volume. If you decrease this value,
even strong strikes on the rim are sounded at low volume.
If the rim sound is heard when you strike the head strongly, increase this value. If the head sound is heard
when you play an open rim shot, decrease this value. If the head sound is heard when you softly play a rim
shot, decrease this value.
MEMO
0–80
If the rim shot sound is heard when you play a head shot, or if a head shot sound is heard when you play
a rim shot, make small changes to the Head/Rim Adj values while you continue trying out the results.
Extreme changes to the values will cause the wrong sound to be heard when you strike the drum trigger,
for example producing the rim shot sound when you play a head shot.
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).
OFF, 1–5
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 TRIGGER IN jacks and specify the Trig Type.
