Double Triggering Prevention (Mask Time); Rim/Edge Dynamic Response (Rim Gain); Rim Shots Response (Rim Shot Adjust); Cross Stick Threshold (Xstick Thrshld) - Roland TD-12 Owner's Manual

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
(Mask Time)
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 specified "Mask Time" (0–64
msec) will be ignored.

Mask Time
Sound not produced
Mask Time: 0–64 (ms)
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.
* When set to a high value, it will be difficult to play very
quickly. Set this to as low a value as you can.
If two or more sounds are being produced when you
strike the head just once, then adjust Retrig Cancel.
Rim/Edge Dynamic Response
(Rim Gain)
When a PD-125/120/105/85/80R, PD-9/8/7, CY series pad,
VH-12/11, or RT-5S (trigger) is connected, you can adjust the
relation between your playing velocity (force) on the rim/
edge and the resulting volume level.
Rim Gain: 0–3.2
Higher value allows the rim/edge to produce a loud volume
even when played softly. Lower value will keep the rim/edge
producing a low volume even when played forcefully.

Rim Shots Response (Rim Shot Adjust)

When a PD-125/120/105/85/80R or RT-5S (trigger) is
connected, you can adjust the sensitivity of the rim response.
RimShot Adjust: 0–8.0
There are some cases that you have a rim sound unexpectedly
when you hit the head strongly. You can improve this
situation with decreasing the value of "RimShot Adjust."
Cross Stick Threshold
(XStick Thrshld)
When a PD-125/120/105/85/80R or RT-5S (trigger) is
connected, you can determine the "cross over point" between
the cross stick and a rim shot sounds.
XStick Thrshld: 0–127
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.

Chapter 5. Trigger Settings [TRIGGER]
* When you set the value too small, it might be difficult to play
the rim sound.
* Increasing the value excessively may cause the cross stick to
sound as well when the open rim shot is played.
