Chapter 7 Changing the Setup (Overall Environment)
Chapter 7
When you set Trig Type, the following parameters are set to their recommended values. However, you’ll need to adjust them so
they more precisely match the way your pads and other devices are mounted, and on how you use them.
When InputMode is set to TRGx2, Sensitivity, Threshold, VeloCrv, Scan Time, RetrigCancel, Mask Time, and XtalkCancel can be
set for individual playing surfaces. Hit a pad/trigger or hold down [SHIFT] and press the PAGE buttons to change the pad/
trigger. Verify with the flashing pad indicators.
Parameter Value Descriptions
Sensitivity 1–16 Define the sensitivity of the pad or the like to control the balance between the strike
force and the sound volume. As the value increases, the sensitivity gets higher, which
means that a louder sound is produced with weak strikes.
Specify the value while watching the velocity indication (p. 77) to ensure that the ve-
locity is at 127 when you strike with the greatest force.
Threshold 0–15 Specify the strike force threshold, above which the SPD-S accepts trigger signals, to
prevent the pad or the like from being affected by the vibrations around it. In the di-
agram below, signal B is played back, but signals A and C are not.
If you specify a high value, no sound is produced when you strike weakly.
Raise the value gradually while hitting the pad or the like. Hit it weakly to check. If
any sound is missing, lower the value slightly. Repeat this control to define the best-
suited value.
VeloCrv
(Velocity
Curve) LINEAR,
EXP1, EXP2,
LOG1, LOG2,
SPLINE,
LOUD1, LOUD2 Specify the velocity curve (p. 78) for the pad or the like to select the mode of change
in volume according to the strike force.
Scan Time 0–4.0 ms Because of a slight variation in the attack time of trigger signal depending on the pad
type or the characteristics peculiar to acoustic drum triggers, the SPD-S may occa-
sionally produce a weaker or stronger sound if you hit a pad at the same strength. In
this case, define the time for the detection of trigger signal (scan time) to ensure that
the strike force is correctly detected.
As the value increases, the time until sound production is increased. Specify the
smallest possible value.
Setting the value
Raise the scan time value gradually from 0 ms while hitting the pad or the like at
the same strength. Set Scan Time to a value at which stable sound is produced with
the largest volume. At this value, hit the pad strongly and weakly to check if prop-
er volume variation is produced.
Specify the value while watching the velocity indication (p. 77) to ensure that the
velocity is at 127 when you strike with the greatest force.
