Location

Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel disguration or damage to the internal components.

(3)-11

Connections
Before connecting the instrument to other electronic components, turn off the power for all components. Before turning the power on or off for all components, set all volume levels to minimum. Also, be sure to set the volumes of all components at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level.
Do not rest your weight on, or place heavy objects on the instrument, and do not use excessive force on the buttons, switches or connectors. Do not use the instrument/device or headphones for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician.

Maintenance

When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning uids, or chemical-impregnated wiping cloths.

Saving data

Never attempt to turn off the power while data is being written to Flash ROM (while a "now storing." message is shown). Turning the power off in this state results in loss of all user data and may cause the system to freeze (due to corruption of data in the Flash ROM). This means that this instrument may not be able to start up properly, even when turning the power on next time.

Handling caution

Never insert or drop paper, metallic, or other objects into the gaps on the panel. If this happens, turn off the power immediately and unplug the power cord from the AC outlet. Then have the instrument inspected by qualied Yamaha service personnel. Do not place vinyl, plastic or rubber objects on the instrument, since this might discolor the panel.
Yamaha cannot be held responsible for damage caused by improper use or modications to the instrument, or data that is lost or destroyed.

1 Connecting the Pads

Referring to the illustration below, connect the output cable from each pad to each Trigger Input jack located on the rear panel of the DTXPRESS IV. All Trigger Input jacks are conveniently labeled (1 SNARE, etc.), so make sure each pad is connected to its corresponding Trigger Input jack.

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 functionin which the sound is cancelled if your timing is offalso 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 Challenge from the Rhythm Gate settings in the GRV2 page. * Hit timing display If your timing is slow or youre dragging the beat, the mark will move to the right side of the display. If your timing is fast or youre 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 specied 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 difculty 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 300. * Inaccurate timing display The average inaccuracies in timing as compared to the note value set in page GRV4 are shown in numeric display. Range: 0 (perfectly accurate), 19 (in units of 1/24 of a 16th note) The deviation in timing inaccuracy is 0.0 to 9.9. Of course, the smaller this value is, more in the pocket your playing is.

Your hit Perfect timing

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 Challenge 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 specic 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)

Select and set the display that you want to be edited from page 3 to page 25 in the KIT screen.
Next, decide the Drum Voice category. Drum Voice categories are the same as those used in the user click sound setting (p. 19). Voice Category K: Kick S: Snare T: Tom C: Cymbal H: Hi-hat P: Percussion E: Effect Here, select K: Kick. Press the [<]/[>] buttons to move the ashing cursor to the Voice Category and rotate the jog dial to select K.

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 IVs trigger input jacks? (p. 10, 11) Is the DTXPRESS IV properly connected to headphones or an external audio device such as an amplier, speaker, etc.? (p. 12) Check the position of the power switches and volume levels of any connected external audio devices, such as an amplier, speaker, etc. The volume knob on the rear panel may be turned down (p. 15). Is the input level displayed when the pad is hit? (p. 38 [TRG3 Gain, MVI (Minimum Velocity)]) Is the gain set too low? (p. 38 [TRG3 Gain, MVI (Minimum Velocity)]) The volume setting on the Drum Kit Select displays 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 and may be set to 00:NoAssign. (p. 29 Step2: [KIT2]) 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 00:NoAssign. (p. 29 Step2: [KIT2])

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)])
I need to restore the original factory settings of the instrument.
Use the Factory Set function (p. 35) to reset the DTXPRESS IV internal settings to the initial factory settings.

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.
