Main Features
The DTXPRESS IV is equipped with a high-quality 32-polyphony tone generator that produces realistic voices, includes a high-performance, multi-function metronome, a built-in sequencer and a variety of songs—all combined into a compact, portable package. The DTXPRESS IV is an exceptionally versatile instrument that can be used in a variety of situations such as live performance, personal practice, and much more.
■ Drum Triggers

• Built into the unit are twelve trigger input jacks and a hi-hat controller jack. The instrument also features jacks that are compatible with two-zone or three-zone pads (pads that transmit different signals depending on the area that is hit).
  Moreover, the snare drum jack is compatible with pad-controller-equipped pads. This lets you adjust the ‘virtual’ snares and the tuning—just as you would with an acoustic snare drum. All in all, the DTXPRESS IV has the operability, functionality and performance that is virtually equivalent to an acoustic drum kit.

• You can connect the DTXPRESS IV to an acoustic drum kit by using drum triggers such as Yamaha DT20. The setup data such as the trigger input types and sensitivity can be customized to suit your playing preferences, style and particular setup.

• Also included in the unit are 50 preset drum kits which naturally contain acoustic drum kits, and cover a wide range of music genres, such as rock, funk, jazz, reggae, Latin, etc. Moreover, User kit memory is available for storing 20 sets.
  With this, you can set up your own original drum kits using the various drum voices.

• The word “trigger” refers to the means by which hitting a pad sends a signal to the DTXPRESS IV as to what sound to play on the built-in tone generator and how loud the sound should be played.

■ Tone Generator

• The DTXPRESS IV is equipped with a high-quality, 16-bit AWM2 (PCM) tone generator with 32-voice polyphony that produces dynamic voices or exceptional realism. The voices—totalling 427—cover a wide range sounds, such as authentic acoustic drums, unique electronic percussion, sound effects, and much more. The instrument also features a built-in high-quality digital reverb for enhancing the sound.

■ High-performance Metronome

• The DTXPRESS IV provides with a comprehensive, multi-function metronome, allowing various click settings for each note value. Each note value can be assigned its own separate click sound and pitch. You can also set a timer that will determine when the click stops and set breaks which how many measures the click will play and then be muted.
• The DTXPRESS IV also features a “Tap” function that lets you set the tempo for the song or click by tapping in tempo on a pad to any tempo you like. This lets you set whatever tempo you desire for playing or practicing.

■ Sequencer

• The built-in sequencer contains a wide variety of 63 preset songs. Two functions that make the DTXPRESS IV great for practice are the Drum Mute Function, which mutes a specific drum part, and the Bass Solo function, which lets you play along with just the song’s bass part. The DTXPRESS IV also allows you to record your performance in real time—and allows you to play along with your recorded performance data.
• In addition to one main song that is controlled from the panel, three pad songs can be individually controlled and simultaneously played by trigger input from the pads.

■ Groove Check

• The Groove Check function monitors your playing and provides instant feedback on your rhythmic skills, providing a powerful way to quickly improve your technique. It includes a Rhythm Gate function that produces sounds only if your timing is accurate, and also has a Challenge mode that evaluates your playing, giving you a letter grade—and makes mastering the drums easier and more fun than ever before.

■ Interface

• A MIDI OUT jack on the rear panel lets you connect other devices and play sounds from an external tone generator or synchronize the metronome with an external sequencer. Also provided are an AUX IN jack, which lets you plug in and play along with an external audio device, such as a CD player or MD player, and a headphones jack for convenient practice without disturbing others.

Using the Groove Check Function

Another highly useful feature of the DTXPRESS IV is the Groove Check function. As you play along with a song or the click, Groove Check compares your timing with the song or click playback and lets you know how accurate your playing is.
The related Rhythm Gate function—in which the sound is cancelled if your timing is off—also offers you a great way to improve your technique.

Groove Check Mode
The Groove Check function has the following two modes.

• Numeric Display Mode
  In this mode, the accuracy of your drum hits is shown in numeric display.
  The aspects shown in the numeric display are the average inaccuracy in the timing of each hit and the deviation in timing inaccuracy of all hits. To use this mode, select one of the modes other than “ ” from the Rhythm Gate settings in the GRV2 page.
• Hit timing display
  If your timing is slow or you’re dragging the beat, the mark will move to the right side of the display. If your timing is fast or you’re pushing the beat, the mark will move to the left.
  Rhythm Gate range
  With the Rhythm Gate function, sound is produced only if the hit is within the specified range, and sound is not produced if the hit is outside this range. The range of Rhythm Gate can be selected from three levels according to the degree of difficulty and if this is set to off, sound is always produced, no matter what your timing is. The selected range is shown in the lower side of the upper half of the display.
  Tempo
  The jog dial can be used to adjust the tempo for the song or click from 30 to

• Inaccurate timing display
  The average inaccuracies in timing as compared to the note value set in page GRV4 are shown in numeric display.
  Range: (perfectly accurate), (in units of 1/24 of a 16th note) The deviation in timing inaccuracy is to . Of course, the smaller this value is, more “in the pocket” your playing is.

  • Challenge Mode
    The DTXPRESS IV automatically evaluates the accuracy of 100 times hits over six grade levels from A to F and sets the range of Rhythm Gate according to the result. The tolerance automatically narrows if your hits are accurate and widens if your hits are inaccurate.
    This mode can be used by selecting “ ” from the Rhythm Gate settings in the GRV2 page.
    * Hit timing display*
    Just as with the Numeric Display mode, your timing is displayed with an icon.
    Rhythm gate range**
    The set range of the Rhythm Gate is shown in the lower side of the upper half of the display.
    After a pad (pads) is hit a specific number of times, the DTXPRESS IV evaluates the accuracy of the hits and sets the range of Rhythm Gate automatically.

  • Hit accuracy evaluation
    In the lower half of the display, the number of remaining hits and the current evaluation result (%) are shown.
    The current level (evaluation) and the status change during playback. If your playing accuracy result (%) was 90% or more, the level is raised one step, and if accuracy is 60% or less, the level is lowered one step.
    • Current level (evaluation): A (best) to F (worst)
    • The icon and the meaning of evaluation
    : Increases the strictness (as you continue playing in the same way)
    : Maintains the same strictness (as you continue playing in the same way)
    : Decreases the strictness (as you continue playing in the same way)

• The level (evaluation) when the challenge mode begins is set to D. *Tempo
Tempo is not shown in the Challenge mode display. To change the tempo, hold the [SHIFT] button and rotate the jog dial. You can adjust the tempo for the song or click from 30 to 300 (the tempo is shown in the LED display).

Now let’s use the Groove Check function.

1. Select a Song or a Click Set
   First, select the song or click set that you want to play along with.

2. Set the Rhythm Gate (select a mode)
   Press the [SHIFT] + [CLICK] buttons to call up page 1 (GRV1) in the Groove Check Setting pagesNext, press the [ ] button once to call up the GRV2 page, then rotate the jog dial to set the Rhythm Gate.● Rhythm Gate settings
   …………….. Sound is always produced
   …………… Wide tolerance for sound production (easy)
   ………. Mid-level tolerance for sound production (average)
   …………….. Narrow tolerance for sound production (difficult)
   … Tolerance changes by automatic evaluation (Challenge mode)A: Range within which sound is produced. (The gate narrows as the setting changes from “easy” to “normal” to “pro.”)
   B: Range within which sound will not be produced even though the pad is struck.

3. Select the Pad
   Press the [>] button to call up the GRV3 page, then rotate the jog dial to select the pad (Trigger Input Source) that you want to check. The “ALL” setting selects all pads.

   [Range] Accent , quarter note , eighth note , sixteenth note , eighth note triplet

5. Start the Groove Check
   After setup is complete, start playback of the song ([SONG ]) or the click sound ([ ON/OFF]) and go back to the Groove Check’s main menu (the GRV1 page).
   Groove Check begins as soon as you hit the pad specified in the GRV3 page.

6. Play as accurately as possible
   Listen to the song or click and concentrate on playing the pads accurately. The jog dial can be used to adjust the tempo for the song or click.
   If the Numeric Display mode is selected, stop the song or click and check the results. Change the Rhythm Gate setting, pad type, or note value as you like and enjoy practicing.

• The Groove Check’s results are reset the next time song or click starts playing.
  If the Challenge mode is selected, when the remaining hits become zero, the final evaluation is displayed in six levels from A to F. With this evaluation, the range over which the sound is produced is set automatically. The higher the evaluation (A is the highest and F the lowest), the narrower the tolerance becomes.
• The Groove Check’s results are reset the next time song or click starts playing. The current level (evaluation) and the range over which sound is produced are also reset.

Record Your Performance

In this section, you’ll learn how to record your performance to the DTXPRESS IV’s built-in sequencer. In the song data you record, you can switch Drum Kits, change the tempo and playback in the same way as with Preset Songs.

Recording System

• Recording can be done with any of the User Songs (64–83). However, you cannot record to Preset Songs (1–63).
• A recorded song doesn’t contain recordings of the audio ‘sounds’ of the drums, but rather the performance ‘information’ or data of precisely when and how each pad was hit. This information is called sequence data. Unlike audio data, sequence data can be freely used to change the tempo, select the voice or drum kit during playback.

Now, let’s start recording…

  14. Set the Alternate Group
      This function allows you to assign different voices to the same alternate group, so that the playing of one sound in the group will automatically cancel others in the same group. A practical example of this is with the open and closed hi-hat voices. When you play an actual hi-hat—first open, then closed—the closed hi-hat naturally mutes the ringing open sound. Likewise, when the open and closed hi-hat voices are assigned to the same alternate group, the playing of one mutes the other.

• This setting has no affect on two-layer input sources. The / indication is not shown in the upper right corner of the display.

Use the [ ] button to call up the KIT14 page, then rotate the jog dial to set the Alternate Group. ……………..No cancellation

Trigger Setup Edit

Trigger Setup Edit contains various settings related to trigger input signals received from pads or drum triggers (Yamaha DT20, etc.) that are connected to the trigger input jacks. These settings let you optimize the DTXPRESS IV for best operation and response to these signals. If you are using drum triggers attached to acoustic drums, or pads other than those that came with the DTXPRESS IV set, you’ll need to adjust the sensitivity.
This section also has settings that help prevent crosstalk and double triggering.

• Crosstalk: The interference between trigger signals of physically adjacent pads, producing unexpected notes.
• Double triggering : The condition where a single pad hit causes multiple (usually two) triggers.

Trigger Setup procedure
If you are using pads or drum triggers other than those that came with your DTXPRESS IV Set (Standard Set/Special Set), or if you need to solve problems with double triggering or crosstalk, the Trigger Setup provides more detailed settings—such as changing the preset’s trigger setup—for individual pads.

1. Three-zone function (pad voice x 1, rim voice x 2) is available if a three-zone compatible pad such as the TP65S, etc. is connected to the 1 SNARE, 5 RIDE, or 6 CRASH input. For producing closed rim shots, the “ ” has a high sensitivity setting on rim 1, while the “ ” has a high sensitivity setting on The same voice is assigned to “ ” and “ ” and the left and right rim sensitivities are set to the same level.
2. Rim1 and rim2 sounds on the “ ” are reversed from those on “ ”. This provides left-handed drummers with a proper setting when using a left-handed setting.
3. When a stereo pad such as the TP80S is connected to the 1SNARE, 5RIDE, or 6CRASH input, “ ” will produce the sound that is assigned to rim 1, and “ ” will produce the sound assigned to rim 2 (p. 28)
4. When using an RHP series stereo pad, connect the pad to Input 2TOM1/10, 3TOM2/11, 4TOM3/12, or 8KICK/9, and set the pad type in “ ”, or “ ” input to “RHP~pad” and the pad type in “ ”, “ ”, or ““ ” to “ .”
5. To use the BP80 as a stereo pad, connect the pad to Input 2TOM1/10, 3TOM2/11, 4TOM3/12, or 8KICK/9.

Gain [Range] 0–99
Adjusts the input gain (sensitivity) for the input jack assigned in the upper half of the page.
Setting a larger value lets a smaller input level from the pad create sound.

• This value will be automatically set after the appropriate pad type is set in [TRG2 Type (Pad Type)]. Some fine-tuning of the value will be necessary.
• Some pads are equipped with a sensitivity adjustment knob. For details, refer to the owner’s manual that came with the particular pad.
  MVI [Range] 1–127
  Sets the MIDI Velocity (volume) that is transmitted when the pad is hit the softest. Large values will produce a high volume level even if the pad is hit softly. However, this will result in a narrow volume range making it difficult to adequately produce wider dynamic levels.
  The Trigger Input Level will be displayed in percentage in the upper right hand corner of the display. The maximum velocity (input level 99 percent) will be 127. The lower the level is when the pad is hit the weakest, the wider the potential dynamic range will be.
• This value is automatically set after the appropriate pad type is set in [TRG2 Type (Pad Type)]. Some fine-tuning of the value will be necessary.Sets the Input Velocity Curve for the input jack assigned in the upper half of the page.Prevents double triggering from occurring in the input jack assigned in the upper half of the page. After an event is detected, further events will be automatically muted for a certain length of time. The larger the value, the longer time events will be muted.Prevents crosstalk from occurring in the input jack assigned in the upper half of the page. Events triggered by other pads (input jacks) that are of a lower input value than what is set here will not be triggered for a certain length of time. Larger values require a greater input level in order to produce a trigger event. RejLvl [Range] 0–9
  Frm [Range] 1–6, 56 (5 and 6), 7–12
  This setting is used to prevent crosstalk between the input jack assigned in the upper half of the page and the input jack assigned in the “ ” setting.
  After an triggering event occurs from the pad that is assigned in the “ ” setting, the pad assigned in the upper half of the display will not sound for a certain length of time unless the input level is greater than the value set here. Larger values will require
  a greater input level in order to produce a trigger event.
  A “ ” setting assigns both trigger input jacks 5 and 6.This function allows you to copy all data settings in pages [TRG2 Type (Pad Type)] through [TRG7 RejLvl (Specified Rejection Level)] to another input jack.
  CAUTION
  When the Trigger Setup Copy operation is carried out, the Trigger Setup data will be replaced with the settings of the copy source.

Operation

1. Hit a pad to select the copy source (input jack) from which the data will be copied.
   Rotate the jog dial and assign the copy destination (input jack).

2. Press the [SAVE/ENTER] button. A prompt appears asking confirmation of the Copy operation.

3. Press the [SAVE/ENTER] button to actually execute the Copy operation.
   *To cancel the Copy operation, press any button except for the [SAVE/ENTER] and [SHIFT] buttons (the jog dial can also be used to cancel the operation).
   The following display appears after the Copy operation is complete.

Error Messages

The DTXPRESS IV displays error messages when incorrect settings have been made or invalid operations have been detected, or when any abnormal operation or malfunction occurs.
If an error message appears, check the list below and make the appropriate corrections.
This message appears just after the power is switched on and the device cannot correctly read the data due to the Factory Reset operation being active.
The backup ROM data may have been damaged. Contact the nearest Yamaha Service Center or the dealer where you purchased the device. You have exceeded the memory capacity of the user song.
Delete unused songs to make more memory available and try recording again. Writing data to the backup ROM has failed.

Trobleshooting

The DTXPRESS IV does not produce sound, or does not recognize trigger inputs.

• Are the pads or drum triggers (Yamaha DT20, etc.) properly connected to the DTXPRESS IV’s trigger input jacks? (p. 10, 11)
• Is the DTXPRESS IV properly connected to headphones or an external audio device such as an amplifier, speaker, etc.? (p. 12)
• Check the position of the Standby/On switches and volume levels of any connected external audio devices, such as an amplifier, speaker, etc.
• The volume knob on the rear panel may be turned down (p. 15).
• Is the gain set too low? (p. 38 [TRG3 Gain, MVI (Minimum Velocity)])
• The volume setting on the Drum Kit Select display’s “KIT3 Volume” page (p. 29) may be set to “0.”
• Is there a problem with the cable you are using?
• The drum voices for both layers may be set to “ (p. 29 Step2: [KIT2])

The external tone generator does not produce sound.

• Is the MIDI cable (connector) properly connected? (p. 13)

• Is the correct MIDI connector being used? (p. 13)

• Are the MIDI note number values appropriate?
  (p. 30 Steps 8 to 10: [KIT8], [KIT9], [KIT10])

• The drum voices for both layers and may be set to   (p. 29 Step2: [KIT2])

A voice other than the set voice is produced.

• Is the transmitting MIDI channel set to a channel that is not used for the drum voice (ch=10)? (p. 30, Step 9: [KIT9])
• Are two-layer voices set in the voice setting on the Drum Kit Select display? (p. 29 Step 2: [KIT2])

Produces sound but the sensitivity is too low (volume is low).

• Is the gain set too low? (p. 38: [TRG3 Gain, MVI (Minimum Velocity)])
• Pads with a level adjustment knob should be adjusted (increased).
• Is the minimum velocity set too low? (p. 38: [TRG3 Gain, MVI (Minimum Velocity)])
• Are you using a proper velocity curve? (p. 38: [TRG4 VelCurve (Velocity Curve)])
• Is the volume of the voice you want to use too low? (p. 29 Step 3: [KIT3])

The trigger sound is not stable. (For acoustic drums)

• Check the entry “Produces sound but the sensitivity is too low (volume is low)” above.
• Tr y 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 (lowered).
• 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 triggering.
• Is the head causing irregular vibrations? It may be necessary to mute the head.
• When using acoustic drums, make sure the Drum Trigger is attached near the rim (above the bearing) and not near the center of the head.
• When using acoustic drums, make sure that nothing is touching the Drum Trigger.

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)])
• When using acoustic drums, place the Drum Trigger away from any nearby drum.

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 producing 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? Depending upon the manufacturer, output levels might be too large.

The DTXPRESS IV does not receive any switch or trigger 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])

• Tu rn the power 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 RHH135/130 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 produce 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])
• The sound produced by the edge and cup section will not be produced when a pad equipped with a rim switch (PCY135/ 155 etc.) is connected to the Input jack 9– 12.
