Roland TD-20 Advanced Trigger Parameters F5 Advance, Trigger Signal Detection Time Scan Time

Chapter 5. Trigger Settings [TRIGGER]

Advanced Trigger Parameters [F5 (ADVANCE)]

The following parameters (Advanced Trigger Parameters) are automatically set to the most efficient values for each pad when you select the Trigger Type (p. 44), and don’t require adjustment, except if you experience any of the problems that are discussed in the explanation of each parameter.

1.Press [TRIGGER] - [F5 (ADVANCE)].

2.Use [F1]–[F3] and [CURSOR (up/down)] to select the parameter.

3.Strike the pad you wish to set.

The setting screen for the struck pad will appear. You can also select by using [TRIG SELECT].

4.Use [+/-] or [VALUE] to adjust the setting.

5.When you’re finished, press [EXIT] to return to the “DRUM KIT” screen.

Trigger Signal Detection Time (Scan Time)

Since the rise time of the trigger signal waveform may differ slightly depending on the characteristics of each pad or acoustic drum trigger (drum pickup), you may notice that identical hits (velocity) may produce sound at different volumes. If this occurs, you can adjust the “Scan Time” so that your way of playing can be detected more precisely.

Scan Time

Time

Scan Time: 0–4.0 (ms)

While repeatedly hitting the pad at a constant force, gradually raise the Scan Time value from 0 msec, until the resulting volume stabilizes at the loudest level. At this setting, try both soft and loud strikes, and make sure that the volume changes appropriately.

*As the value is set higher, the time it takes for the sound to be played increases. Set this to the lowest value possible.

Detecting Trigger Signal Attenuation (Retrigger Cancel)

Important if you are using acoustic drum triggers. Such

triggers can produce altered waveforms, which may also

cause inadvertent sounding at Point A in the following figure

(Retrigger).

A

Time

This occurs in particular at the decaying edge of the

waveform. Retrigger Cancel detects such distortion in and

prevents retriggering from occurring.

Retrig Cancel: 1–16

While repeatedly striking the pad, raise the “Retrig Cancel”

value until retriggering no longer occurs.

*Although setting this to a high value prevents retriggering, it then becomes easy for sounds to be omitted when the drums played fast (roll etc.). Set this to the lowest value possible while still ensuring that there is no retriggering.
