DTXPRESS
IV
Owner’s Manual
The trigger sound is not stable. (For acoustic drums)
●
Check the entry “Produces sound but the sensitivity is too low
(volume is low)” above.
●
Try selecting a larger pad type setting (DT snare
→
DT HiTom
→
DT LoTom
→
DT Kick). (p. 37: [TRG2 Type (Pad Type)])
●
Is the Drum Trigger (Yamaha DT20, etc.) improperly attached
with duct tape? (Is there any old adhesive remaining on the
head?)
●
Is the cable securely connected to the drum trigger (Yamaha
DT20, etc.) jack?
Double triggering is produced.
●
Pads with a level adjustment knob should be adjusted (low-
ered).
●
Is the gain set too high? (p. 38: [TRG3 Gain, MVI (Minimum
Velocity)])
●
Use the self-rejection setting. (p. 38: [TRG5 RejTime (Self
Rejection Time)])
●
(KP65)
Is the pad type for the input jack to which the KP65 is
connected set to Kick Pad? (p. 37: [TRG2 Pad Type])
●
Are you using drum triggers (trigger sensors) made by other
manufacturers? Too large a signal can result in double trigger-
ing.
●
Is the head causing irregular vibrations? It may be necessary
to mute the head.
●
Is the sensor attached close to the center of the head? Move
the sensor closer to the rim.
●
Is the sensor in contact with anything else?
Crosstalk (trigger interference from different inputs) is
produced.
●
Is the gain set too high? (p. 38: [TRG3 Gain, MVI (Minimum
Velocity)])
●
Try increasing the rejection parameter. However, avoid setting
this value too high since that may cause the sound to not be
produced when another pad (trigger input) is hit at the same
time. (p. 38: [TRG6 RejLvlAll (Rejection Level)])
●
If crosstalk is produced with a specific trigger input, try using
specific rejection. (p. 38: [TRG7 RejLvl (Specified Rejection
Level)])
●
Try placing sensors (Yamaha DT20, etc.) away from nearby
drums.
Sounds are cut when you play continuously.
●
The maximum polyphony of 32 voices might be exceeded. In
the Drum Kit Select dispaly’s “KIT15 Key Assign Mode” page
(p. 31), set the “KeyAssign” value to “semi” or “mono.”
When two pads (drums) are played only one sound is
heard.
●
Raise the gain setting of the pad (trigger input) that is not pro-
ducing sound. (p. 38: [TRG3 Gain, MVI (Minimum Velocity)])
●
Lower the rejection setting of the pad (trigger input) that is not
producing sound. (p. 38: [TRG6 RejLvlAll (Rejection Level)])
●
Lower the specified rejection setting of the pad (trigger input)
that is not producing sound (p. 38: [TRG7 RejLvl (Specified
Rejection Level)])
●
Are both pads (trigger inputs) set to the same alternate group?
(p. 31 Step 14: [KIT14])
The sound is always loud.
●
Is the minimum velocities minimum value set too high? (p. 38:
[TRG3 Gain, MVI (Minimum Velocity)])
●
Are you using an appropriate velocity curve? (p. 38: [TRG4
VelCurve (Velocity Curve)])
●
Are you using a pad made by another manufacturer? Depend-
ing upon the manufacturer, output levels might be too large.
The DTXPRESS IV does not receive any switch or trig-
ger signals.
●
If you can access the Utility display, perform the Factory Set
operation. The DTXPRESS IV will reset to its factory settings.
(p. 35: [UTIL8 Factory Set])
●
Turn the POWER switch OFF then ON while holding the [
<
]
and [
>
] buttons together. The DTXPRESS IV will reset to its
factory settings.
The sound does not stop.
●
Some voices have very long release times when the “key off”
parameter is set to “disable.” (p. 30 Step 11: [KIT11])
Press the [DRUM KIT] button to temporarily stop the sound.
The pad controller function does not work
●
Have you connected a pad equipped with a pad controller,
such as the TP100 or TP120SD?
●
Are the pad controller settings properly set? (p. 17)
The Closed Hi-Hat voice is not produced.
●
Is the proper pad type selected? If the RHH130 is used as a hi-
hat controller, the pad type must be set to “RHH.” (p. 37: [TRG2
Pad Type])
The edge or cup sections of the cymbal pad do not pro-
duce sound when struck. The choke functions do not
work.
●
Is the proper pad type selected? Select the appropriate pad
type for the kind of cymbal pad you are using. (p. 37: [TRG2
Pad Type])
Foot Splashes are not produced.
●
Is the foot controller connected to the HI HAT CONTROL jack?
●
Adjust the detection time of foot splashes. (p. 16: Adjusting the
Hi-hat)
