Setting Up

To prevent electric shock and damage to the devices, make sure the power is switched OFF on the DTXPRESS III and all related devices before making any connections to the DTXPRESS IIIs input and output jacks.

s Connecting the pads

Referring to the illustration shown below, connect the output cable from each pad to each Trigger Input Jack located on the rear panel of the DTXPRESS III. The Trigger Input Jacks are all labeled (1 KICK, etc.) so make sure you connect each pad to its corresponding Trigger Input Jack.

Standard set

to 7 CRASH1

to 6 RIDE

The hi-hat drum pad clamp can also be attached to this arm.

to 3 TOM1 to 8 HI HAT

to 4 TOM2
to 2 SNARE to 1 KICK Caution) A cable equipped with a stereo plug is required when connecting the Hi-Hat Controller.

to 5 TOM3

to HI HAT CONTROL
The DTXPRESS IIIs Trigger Settings will need to be changed according to the type of drum set you are using (Standard Set/Special Set/Acoustic Drums/etc.). Refer to the Select Trigger Setup section described on the next page on how to select the appropriate setup.

Special set

to 9 CRASH2 to 3 TOM1 to 4 TOM2
to 8 HI HAT, HI HAT CONTROL

to 1 KICK

to 2 SNARE
* When a double foot pedal setup is used, we recommend slightly rotating the leg on the left side of the rack to allow more space for the foot pedal. (Make sure you loosen the bolts before rotating the leg. Not doing so can damage the rack.)

s Select Trigger Setup

This setting lets you select the Trigger Setup that is best matched to the particular drum set you are using. If you switch the type of drum set you are using with the DTXPRESS III, make sure you use the procedure below to select an appropriate setup. q Some Advice on Connections Trigger Input Jacks from 1 KICK to 8 HI HAT are stereo input type jacks. Pads equipped with trigger switches like the TP65S, PCY65S, PCY130S, etc. can be connected to these jacks. 3-zone pads like the TP65S, PCY150S, etc. can be connected to Trigger Input Jacks 2 SNARE, 6 RIDE, and 7 CRASH1. The DTXPRESS IIIs input jack parameters are preset with settings suitable for pads that correspond to the inputs label (KICK, SNARE, etc.). If any other type of pad is going to be connected to an input jack, that jacks parameters (sensitivity, etc.) should be changed to settings that suit the pad. Sensitivity is set in the Trigger Setup Edit modes [1-1. Pad Type] (Reference Guide : P. 12). The input sensitivity switches (INPUT ATTENUATION) are sensitivity switches that correspond to Trigger Input Jacks 1 KICK-6 RIDE. The switchs L position corresponds to a low sensitivity for pads like TP, KP, PCY, BP, etc. The H position corresponds to a high sensitivity proper for use with the DT20 Drum Trigger, etc. The HH series Hi-Hat Controller can be used as a kick pedal (assign settings in section [1-1. Pad Type] (Reference Guide : P. 12)). In addition to the 1 KICK jack, the 9 CRASH2/10 jack can be used to connect a second bass drum pedal to create a double-bass drum set. The 9 CRASH2/10 jacks correspond to a 2-trigger input that uses a stereo jack for L (9) and R (10). You can use an conversion cable plug (stereo plug m monaural plug x2) to input two separate trigger signals. When a stereo cable is used to connect the KP65 Kick Pad, you can use the KP65s Input Jack as the input for the DTXPRESS IIIs Trigger Input Jack 10 (assign settings in section [2-3. Input Exchange] (Reference Guide : P. 15).

q PC-1

8-pin MINI DIN to D-SUB 25-pin cable. If your PC-1 type computer has a 9-pin serial port, use the PC-2 type cable. Maximum length 1.8 meters.
2. Connect the DTXPRESS IIIs MIDI IN jack to the computer through a MIDI interface.
If you are using a computer equipped with a MIDI interface, connect the MIDI OUT jack on the computer to the MIDI IN jack on the DTXPRESS III. Set the HOST SELECT switch to the MIDI position. If you are using a Macintosh series computer with an external MIDI interface, connect the MIDI interface to the computers RS-422 jack (modem or printer port), connect the MIDI OUT jack on the interface to the MIDI IN jack on the DTXPRESS III. Set the HOST SELECT switch to the MIDI position.
* When the HOST SELECT switch is set to the MIDI position, the transmission and reception via the TO HOST jack is ignored.

q PC-2
8-pin MINI DIN to D-SUB 9-pin cable. Maximum length 1.8 meters.
If you are using a computer equipped with a USB port, you can connect the DTXPRESS III to your computer via a USBMIDI interface such as the YAMAHA UX16/96/256, etc.

Windows Users

Before you can exchange data between the DTXPRESS III and your computer using the DTXPRESS IIIs TO HOST jack and your computers serial port connections, you will need a suitable MIDI driver (Yamaha CBX Driver (For Windows)) installed in your computer. You can download the Yamaha CBX Driver from the XG library at the Yamaha website given below. http://www.yamaha-xg.com/

A voice other than the set voice is produced.
q Is the transmitting MIDI channel set to a channel that is not used for the drum voice (ch=10)? (m Reference Guide : P. 19 [1-7. Channel, Gate Time]) q Is the Voice=2 parameter set for a 2 layer voice? (m Reference Guide : P. 18 [1-1. Voice])
Produces sound but the sensitivity is too low (volume is low).
q Is the gain set too low? (m Reference Guide : P. 12 [1-2. Gain, Minimum Velocity]) q Pads with output or sensitivity control volumes should be adjusted (increased). q Is the minimum velocity set too low? (m Reference Guide : P. 12 [1-2. Gain, Minimum Velocity]) q Is a proper velocity curve being used? (m Reference Guide : P. 13 [1-3. Velocity Curve]) q Is the volume of the voice you want to use too low? (m Reference Guide : P. 18 [1-2. Volume, Pan]) q Is the drum head getting old? q Change the INPUT ATTENUATION setting on the rear panel. (m P. 9)
The trigger sound is not stable (for acoustic drums).
q Check the Produces sound but the sensitivity is too low (volume is low). list above. q Is the proper pad type set? Select a larger pad type setting (DT snare m DT hi tom m DT lo tom m DT kick 1 m DT kick 2) (m Reference Guide : P. 12 [1-1. Pad Type]) q Is the DT20 properly attached with sticky tape? (Is there any old sticky tape remaining on the head?) (m P. 13) q Is the cable securely connected to the DT20 jack?
Double-triggers (when 2 sounds are played at the same time) are produced.
q Are you using a sensor made by a manufacturer other than Yamaha? If the signal is too large, double-triggers may be produced. q Is the head causing irregular vibrations? It may be necessary to mute the head. q Is the sensor attached close to the center of the head? Move the sensor closer to the rim (above the bearing). (m P. 13) q Is the sensor in contact with anything else? q Pads with output or sensitivity control volumes should be adjusted (lowered).
q Try increasing the rejection parameter. However, a setting a value that is too high may cause the sound to be muted when another drum is hit at the same time. (m Reference Guide : P. 13 [1-4. Self-Rejection, Rejection]) q Use the self-rejection. (m Reference Guide : P. 13 [1-4. Self-Rejection, Rejection]) q Change the INPUT ATTENUATION setting on the rear panel. (m P. 9)
Cross-talk (mixed signals from different inputs) is produced.
