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 songsall 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 tuningjust 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 voicestotalling 427cover 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.

In the case of the duplicate input sources, the same voice will be output. If the setting is not available because of an already assigned MIDI note number, (Note# in use) or (# in use) is shown in the lower half of the display.

12 Set the Hold Mode

Every time the pad is hit, Key On and Key Off messages are alternately sent. This means that one hit of the pad turns the sound on and the next turns it off.

* When this is set to on, you should also set the Key Assign Mode to high in the KIT15 page.
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-hatrst open, then closedthe 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.

TRG6 ~snare~~0% ~RejLvlAll=2~~

[Range]

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 difcult 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 ne-tuning of the value will be necessary.
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 (Specied Rejection Level)
TRG7~ snare~~0% RejLv1=3Frm=56
RejLvl [Range] Frm [Range] 09 16, 56 (5 and 6), 712
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 Frm= setting.
After an triggering event occurs from the pad that is assigned in the Frm= 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 Frm=56 setting assigns both trigger input jacks 5 and 6.
CopyToInput (Trigger Setup Copy)
TRG8 ~snare CopyToInput=~2
This function allows you to copy all data settings in pages [TRG2 Type (Pad Type)] through [TRG7 RejLvl (Specied Rejection Level)] to another input jack.
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).

yDTXPRESS IV QUICK START GROOVE CHECK: BASIC SKILLS
Without a doubt one of the most important skills for a drummer is timekeeping. The feature we call Groove Check is designed to help tighten up your timekeeping skills - one beat at a time. It works like a scale that measures how far ahead or behind the beat your hits are. You can measure hits from all inputs or focus Groove Check to analyze a specific pad input. Whats more, you can set the note values for rhythmic analysis from a whole note to eighth note triplet. Lets learn about Groove Check by setting it up to analyze how you play your back beat. 1. Press [SHIFT] + [CLICK] to call up the Groove Check display [GRV1] page.
(appears only if Rhythm Gate is on)
2. Press PAGE two times to get to the Groove Input select [GRV3] page. Rotate the jog-dial to select 1snare as the input. This will analyze just the timing of snare hits.
again to get to the Groove Note value [GRV4] page. Set the Note value 3. Press PAGE to Quarter Notes. This will analyze the accuracy of hits that occur on quarter notes.
4. Now press PAGE button until you get to the GRV1 page. Press the to activate the metronome and try playing a simple drum beat with the back beat 2 and 4 on the snare pad. Understanding the display: As you play to the click, Groove Check shows your hit in relation to a perfect quarter note. If your timing is rushing and you are ahead of the beat, your hit marks will move to the left. If your timing is dragging and you are behind the beat, your hit marks will move to the right. Average inaccuracies are shown in units of 1/24 of a 16th note. This is a mechanical evaluation. The deviation in timing inaccuracy is 0.0 to 9.9. This is a musical evaluation. The smaller this value is, more in the pocket your playing is. In other words, you might stray right or left of center, but at least you are being consistent about it. Some drummers (David Garibaldi, Steve Gadd both Yamaha guys) will sit their quarter notes a certain way to make the music feel a certain way. Groove Check can show you where YOU tend to place your quarter notes so you can work on it. To use it with the songs set up groove check first, play the song, and return to groove check mode.
TIP: Try groove check at different tempos, or try the above example with other inputs and note values.
