Introduction to Bar Triggers
Drum triggers began gaining popularity in the 1990s, and since the beginning of their adoption, the technology has evolved significantly to offer more reliable and versatile solutions. For those interested in more technical details about drum triggers and piezo technology, Wikipedia provides a comprehensive overview. These articles serve as a detailed resource for DIY drum trigger conversion.
Our Bar triggers are a specialized type of electronic drum trigger designed to be attached directly to the drum shell, offering drummers precise control over the sound produced by their instrument. These triggers use a piezo element to detect vibrations and strokes on the drum head, translating each hit into a consistent electronic signal. This means that, unlike traditional microphones, bar triggers can capture a wide dynamic range and respond accurately to even the most subtle playing techniques.
When selecting bar triggers for your electronic drum setup, it’s important to consider the type of drum head you’re using, as these factors influence how the trigger responds to your playing. For example, a drummer playing fast, aggressive music may require a more sensitive trigger to ensure every stroke is detected, while someone seeking a more controlled sound might opt for a less sensitive option. Bar triggers are designed to be versatile, making them suitable for a variety of musical styles and performance settings.
How are they constructed?:
Our Foam Cone Trigger Bars are constructed of 3mm Aluminium in a proven, sturdy U shape. Each unit comes with the following:
-
2 x location holes for the Main Foam Trigger to accommodate individual playing styles and preferences.
-
A Threaded Rod allowing 15mm up and down movement of the Main Foam Trigger, so you can adjust the form and height of the foam cone for best performance. The form of the foam cone and piezo disc affects the distribution of force and helps reduce hotspots.
-
A Main Foam Trigger with plug end.
-
A separate Piezo Trigger (for Rim Shots) to attach inside the drum shell using the applied double sided tape - also supplied with a plug end. Placing the piezo near the edge of the drum head can increase sensitivity to rim shots.
-
A 13mm Female Stereo Adaptor with plug ends to accept the Main and Rim Shot triggers.
-
A 2mtr Stereo TRS Cable.
All triggers must be properly connected to your drum module to ensure accurate signal detection.
For those interested in technical detail, using an oscilloscope can help test the electrical signal from the piezo, which generates a voltage pulse when struck. The meaning of piezo technology in drum triggers is that it converts mechanical vibrations into electrical signals for the module to process. In my opinion, jack sockets offer more flexibility than plugs for DIY builds. Remember, the physical matter of the setup is less important than managing signal quality and proper connections for reliable triggering.
The tools required are - A Drum Key (to remove and replace head), A Phillips Head Screw Driver (long and short) and a Battery Drill with a Sharp 13mm Drill Bit for female adaptor.
Drum Head Interaction
The relationship between the drum head and the trigger cone is a key factor in determining the overall sound and dynamic range of your electronic drum. The drum head’s material and thickness play a significant role in how vibrations and strokes are transmitted to the trigger. Thicker drum heads tend to produce a more muted sound, while thinner heads allow for a brighter, more responsive tone. The trigger cone, often made from foam or similar materials, sits in contact with the drum head and is responsible for transferring the energy from each hit to the piezo element.A well-designed trigger cone made from soft foam can help reduce the “hotspot” effect, where certain areas of the drum head are overly sensitive, and instead provide a more even response across the entire head. Adjusting the trigger system to account for the specific interaction between your drum head and trigger cone is essential for achieving the desired sound and dynamic range. By paying attention to these details, drummers can optimize their electronic drum setup for both feel and sound quality.
What Sizes are available?:
Our triggers are available in the following sizes:
8” - 10” - 12” - 13” - 14” - 15” - 16” - 18” - 20” - 22” - 24”
These trigger sizes are suitable for toms, Floor toms, snares and Bass Drums
We can also customize for you if your size is not listed - please contact us if this is required. Customizing trigger sizes can improve triggering accuracy for toms and other drums.
Mounting and Installation
Proper mounting and installation of bar triggers is crucial for getting the best performance from your electronic drum setup. The trigger should be securely attached to the drum shell or drum head using a suitable material, such as electrical tape or a dedicated mounting bracket, to ensure it stays in place during play. It’s important to manage the wires and connections carefully, keeping them organized and protected to prevent damage or unwanted noise. Using damping materials like foam or rubber can help minimize unwanted vibrations and ensure that only the intended strokes are detected by the trigger.
When installing multiple triggers, such as a system with several piezos for different drum heads, it’s essential to consider the overall trigger system design. Adjusting the sensitivity and settings on your drum module will help you achieve the desired dynamic range and sound, especially if your setup is more complex. For example, a drummer using a multi-trigger system with a multople piezos may need to fine-tune each trigger to account for increased sensitivity and vibration detection. By taking the time to install and adjust your triggers properly, you can ensure a reliable and responsive electronic drum experience.
What drum modules will these triggers work with?:
These triggers will work well with any Drum Module that accepts a 6.35mm TRS Cable
What should I expect from my drum trigger?:
It should be noted that these drum triggers will need to be “dialled in” to your chosen module to achieve the best possible outcome. As each module is constructed differently it cannot be assumed that the perfect setting will work straight out of the box.
During setup, you may encounter hot spots on the trigger surface, where the maximum force is transferred and the sensor is most sensitive; adjusting your settings can help minimize these hot spots.
Once properly configured, you can expect reliable and consistent performance from the triggers, meeting the quality standards anticipated by most users.
