Using the Groove Check Function

Another highly useful feature of the DTX500 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 tim-

ing inaccuracy of all hits. To use this mode, select one of the

modes other than "Challenge" from the Rhythm Gate set-

tings 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 300.

* Inaccurate timing display

The average inaccuracies in timing as compared to the

note value set in page GRV4 are shown in numeric dis-

play. Range: 0 (perfectly accurate), 1–9 (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.

times hits over six grade levels from A to F and sets the range

of Rhythm Gate according to the result. The tolerance auto-

matically 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 speciﬁc number of times, the

DTX500 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 dur-

ing 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 play-

ing in the same way)

: Decreases the strictness (as you continue playing in

the same way)

NOTE

• 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).
