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.
