Roland SPD-20 用户手册

This type of Trigger (TRIG TYPE) is for drum pads whose output of the Trigger signal wave-
form’s attack is slow.  In order to reliably detect the strength with which the pad is struck, the
time set for detection of the trigger (Scan Time; p. 51) is as slow as 1–2 msec.  When using other
manufacturers’ pads, if while playing with the Trigger Type set to “Pd7” you notice the sound
strength or dynamics are unstable, you should reset the Trigger Type to “P1” or “P2.”

For faster sound expression, set to “P1” or “P2” (“K1” or “K2”).

When you make settings for the Trigger Type, a number of internal parameters that do not appear
on the panel are set automatically.  These parameters are known as Advanced TRIGGER parame-
ters.  Normally, no detailed settings are necessary to match the selected Trigger Type, but when
you get poor sound, even having set the Trigger Type, or when using pads or acoustic drum trig-
gers not covered by a particular Trigger Type, then set the Advanced TRIGGER parameters as
needed (p. 48).

Advanced TRIGGER Parameter

Description

Scan Time

Sets the time for detecting the trigger signal

Retrigger Cancel

Detects the attenuation of the trigger signal and cancels subse-
quent incorrect triggering

Mask Time

Cancels secondary sounding of the kick pad and other pads

Crosstalk Cancel

Cancels triggering caused by vibration from other pads

Rim Sensitivity

Adjusts the PD-120’s Rim Sensitivity
