Internal Design of the DTX700 In this reference section, you will find a description of what takes place within the DTX700 between striking of a pad and the output of sound from speakers. Understanding how signals flow and are processed internally will allow you to utilize the powerful functions of this versatile instrument to their maximum potential. Pads & Trigger Signals Whenever you strike a pad, a trigger signal containing various items of performance data will be produced. These signals typically reflect the strength with which the pad was struck, the actual location of the strike, and the like; furthermore, they are delivered via a cable and a trigger input jack to the DTX700's internal tone generator, which outputs the appropriate drum sounds in response. If a pad is set up to generate just one sound, there will be a one-toone relationship between the trigger signal type and the drum voice output. With certain types of pad, however, it is possible to produce a range of different types of trigger signal that reflect the location of the strike, the drumming technique being used, and other factors. [Terminology] Zone: The term "zone" is used to refer to specific areas of the pad, such as the rim, cup, and head. Pads with multiple zones (such as two- and three-zone pads) can produce a different trigger signal for each. As their name suggests, one-zone pads produce only one signal irrespective of where they are struck. Trigger input source: Trigger input sources are named in accordance with the way in which the corresponding pad or pedal is struck or operated.  Two- and three-zone pads (producing multiple trigger signals) In contrast to the PCY65 Single Zone Cymbal Pad and other mono pads, multi-zone pads such as the PCY65S Double Zone Cymbal Pad can produce two different types of trigger signal depending on the zone that is struck, while the PCY135 Triple Zone Cymbal Pad can produce three. In specific terms, multizone pads come in either the two-zone or three-zone variety. For instance, the PCY135 Triple Zone Cymbal Pad illustrated below comprises three trigger input sources - the bow, the edge, and the cup - each of which generates a trigger input signal when struck. Example: PCY135 trigger input sources when connected to the [yCRASH1] trigger input jack Trigger input source: "Crash1Bw" Bow Trigger input source: "Crash1Eg" Edge Trigger input source: "Crash1Cp" Cup The voice assigned to the bow's trigger input source will be played. The voice assigned to the edge's trigger input source will be played. The voice assigned to the cup's trigger input source will be played.  One-zone pads (producing a single trigger signal) A mono pad such as the TP65 Single Zone Drum Pad or PCY65 Single Zone Cymbal Pad transmits only one type of trigger signal to the DTX700, irrespective of where it is struck.
