Connecting External Pads and Pedals

The OCTAPAD lets you connect a hi-hat control pedal, and also connect pedals or pads to the external trigger inputs.
After connecting an external pad or pedal to an EXTERNAL TRIGGER INPUT 1–4 jack, specify the Trigger Type setting as described below.

External Trigger Settings

1. Press the [SYSTEM] button.
2. Use the [K][J] buttons to select "EXT TRIG."
3. Press the [ENTER] button.
4. Strike or press the external pad or pedal that's connected to the EXTERNAL TRIGGER INPUT 1–4 jack to select it.
You can also make this selection by holding down the [ENTER] and using the [K][J] buttons.
5. Use the [K][J] buttons to select the item that you want to edit.
6. Use the [–][+] buttons to select the value.

Explanation
Specifies the model of pad (trigger type) that is connected to EXTERNAL TRIGGER INPUT 1–4 jacks.
MEMO
When you specify the trigger type, the trigger parameters (with the exception of certain parameters
such as cross-stick cancel) are set to optimal values. These values are only general guidelines; you can
make fine adjustments as appropriate according to how you attach the pad and how you use it.
For an explanation of Sens, Threshold, and Curve, refer to "Specifying the Pad Sensitivity" (p. 21).
Trigger signal detection 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.
While repeatedly hitting the drum trigger 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.
