Home Music Motorcycles Software & Computers Electronic Drum Pad Research & Development

In 1993, out of necessity, I invented and prototyped a set of electronic drum pads called "The Trig X-Q". Trig X-Q stands for "trigger extra quiet". The main objective was to create a set of electronic drum pads that would not disturb my neighbors when played. :)

During the R&D process I was also able to resolved a few issues that plagued the current (1993) electronic drum pad on the market. The pads have stood the test of time and work/play wonderfully to this day.

I've only tested and performed the Trig X-Q's with the Alesis D4 Drum Module. The Alesis D4 was one the first Drum Modules to combine a trigger-to-midi interface and sound canvas/samples into one unit.

Improvements:

1. Issue: Cross talk:

Background: Cross talk is when multiple drum pads mounted to one rack or stand get triggered when striking one pad.

 

Resolution:

- I resolved this issue by creating a float - type mounting system for each pad.

- Also, the pads mounting system adds small amount of "give" and/or "movement" to the pad when struck. This "give" attibutes to the "feel" of the pad when played.

 

2. Issue: Drum Feel and Sensitivity:

Background: In 1993, most drum pads used corrugated wood and a thin ply of rubber for striking surface. This resulted in a "non drum like" and/or "non drum practice pad" like feel when being played. The reason for this combination of materials was to protect the pad's trigger from being destroyed when the pad was struck hard. This was effective for the drum trigger "piezo transducer" but not effective for the "feel" when played.

 

Resolution:

- I resolved the "feel" and "trigger protection" issues by coming up with a combination of materials that allowed the trigger to be mounted close the striking surface without getting destroyed when the pad was struck hard.

- Getting the trigger close the hitting surface improved the sensitivity of the pad. Thus allowing ghost-notes and buzz rolls to be triggered effectively.
