Chapter 6: External Triggering

Note: Note Chase will not follow any trigger that has been set to Unassigned. To view an Unassigned trigger’s VU-style bar graph meter in order to adjust gain (page 44), use the [VALUE] knob to select the corresponding trigger input (page 43).

CROSSTALK

If several pads are mounted on one stand or rack it is possible to experience interaction or “crosstalk” problems. Adjustment of the Xtalk parameter makes it possible to resolve these problems.

Note: In configurations where some pads are individually mounted, the default setting of 30 may be sufficient, making it unnecessary to adjust this parameter. In that case, skip this section and go on to the next section, “Decay”.

With the Xtalk parameter selected (flashing), turn the [VALUE] knob to select the desired level of crosstalk suppression necessary to stop the problem pad from triggering (00 is minimum, 99 maximum). This level will depend entirely on your current pad or drum configuration.

Remember: When experiencing an interaction problem, the trigger that needs adjustment is the pad that is false triggering, not the pad being struck. One easy way to remedy an interaction problem is to “silence” the pad(s) which are not “false triggering”.

Example: Suppose you hit the snare pad and the tom 1 pad triggers.

First, press [MIX] and reduce the volume of the snare pad to 00. Now when you hit the snare pad you won’t hear it, but you’ll hear the tom 1 pad false triggering.

Next, press the [EXT TRIG] button twice (which gets you to the Xtalk parameter on page 2) and select the tom 1 trigger to edit.

Press the [] button once to select the Xtalk parameter. While you hit the snare pad (false triggering the tom pad) gradually raise the crosstalk level of the tom 1 pad. Continue to raise the level until the tom pad stops triggering when you apply hard hits to the snare pad. By using this technique, you have isolated the problem drum, and made it easy to “dial in” the proper Xtalk value without the sound from the other drum becoming distracting or confusing.

Finally, press [MIX] again and reset the volume of the snare pad to it’s original level.

Note: Always increase the Xtalk value in small amounts for two reasons. The values are very sensitive, so an increase of as little as 2 or 3 can make a difference in suppression. Also, an unnecessarily high Xtalk setting actually suppresses the sensitivity of the trigger input, resulting in the occasional loss of softer hits.

If a situation where a high Xtalk setting is necessary to stop false triggering, but pad sensitivity loss is noticeable, try this combination. Start by slightly lowering the Gain setting for the pad. This should make it possible to lower the Xtalk value, which will allow the pad sensitivity to increase. With some experimentation and time, you should be able to find the right combination.
