If a situation where a high XTALK setting is necessary to stop false triggering, but pad sensitivity loss is noticeable, try this combination.

Rotate the Data knob and select the note to which you want to assign a particular drum sound. In essence, the D4 isolates the bass from the noise floor and “thinks” the bass is a another drum pad.

Group Determines how a drum sound or group of drum sounds will respond to successive series of triggers. This makes the headphone outs more compatible with pro headphones than the 8Q consumer variety.

A newly-triggered voice assigned to a particular group 1 or 2 will cut off a voice assigned to the same group if the older voice is still sustaining. A higher value adjustment equals greater suppression of the signal, a lower value equals less suppression. First, you strike a pad and the D4 triggers its sound. The top line of each of these screens shows the note that is being edited. These transducers can be plugged directly into the D4 trigger input, which will convert the trigger’s signal to MIDI information.

Not all controller manuall have been standardized for specific functions, but the following indicates the current list of assigned controllers. By adjusting the crosstalk level to a higher value, you set a higher threshold for the signal to exceed, and reduce the ability of a pad drum to crosstalk.
