Don’t Pull That Trigger!
True Dual-Trigger, Mesh Pads
True dual-trigger pads use two piezos, one to trigger the head and the other to trigger the rim. Most true dual-trigger pads have mesh heads. All piezo-based dual-trigger acoustic drum triggers are true dual-trigger devices. These would include pads and triggers from PinTech, Ddrum, and Roland. Beware, many drum modules do not accept true dual-trigger pads. There is still some proprietary technology in the e-drum world. Plugging this type of device into an input designed for membrane-switching pads will more than likely result in only the head portion of the pad or trigger working. Don’t be afraid; this mismatch won’t harm anything in the module. It truly is difficult to make smoke pour from a drum module!
Although there have been a few FSR-based pads around for some time, the new Aquarian onHead pads, and inHead acoustic-electric drumheads are set to make FSR technology much more prevalent. Unless you are using a module that can supply the needed powered circuit to the FSR – there’s only one right now, the DITI trigger interface from Alternate Mode – you’ll have to use a special interface box between the FSR and the module. It’s available as a bundle with the inHead and onHead products.
Understanding Drum Modules: Types of Trigger Inputs
The types of trigger inputs available on drum modules can be broken down into four basic types: single trigger, membrane switching (dual and triple trigger), true dual trigger, and FSR. All of these inputs work slightly differently from one another.
1) Single-Trigger Inputs
The single-trigger input is self-explanatory. With single-trigger inputs, no matter what type of pad or type of cable you use, the pad will only function as a single-trigger pad. Only one sound at a time can be assigned to the pad. A mono cable is needed to connect to the module. A stereo cable with also work, but is not required.
2) Membrane-Switching Inputs
Membrane-switching is the most common type of input. This input type requires the use of a stereo cable to connect the pad to the module. If a mono cable (guitar cable) is mistakenly used, the pad will only trigger from the head. If your rim trigger isn’t working, check and see if you’ve made this mistake. I have never made this mistake ... no, not ever.
3) True Dual-Trigger Inputs
True dual-trigger inputs allow for the use of pads that are designed with two piezo elements, one for the head, and another for the rim. This input type also requires the use of a stereo cable.
4) FSR Inputs
Currently, dedicated FSR inputs are only found on the new Alternate Mode DITI (Drum Intelligent Digital Interface – Fig. 5) module. They allow for FSR-based pads and acoustic heads to be plugged directly into the module without using a special FSR interface box.
