- This video will describe how to build a very simple drum trigger using a FSR. Most drum triggers are Piezo based unlike a FSR trigger which is resistor based.

Really great and unique applications thanks for the ideas !!
Sound really cool!
Nice
Thanks
Any idea how to build a membrane switch to use on cymbal pad rims? Just need it to be a switch that is normally open and closes when hit with the sticks... off/on

Can the FSR trigger be placed under a mesh head and on the rim of the drum?
Does the module pickup the 0-127 velocity range from this?
Hello Sir.. I have Carlsbro 130 E drum kit, and this drum kit has 3 zone rubber snare..so i am trying to make 2 separate pad from 3zone snare using splitter wire but its not working, so how i can make 2 spearate drum pad from 3zone snare
You had me at "connected up to my kick drum" . I was hoping for some Flashforth midi would follow. Do you cover midi in any of your videos? Would enjoy that immensely.
Back in the day I did a lot of work for local bands in the area but not so much now. I have no MIDI videos as I sold all my equipment some time ago.
Hey! How did you get the drum sound to trigger? I got the Max for live connection kit to recognize the signal but it can only map things like volume faders, knobs etc. Which DAW are you using?
It's just an old Yamaha electronic drum kit with inputs for external triggers.
Another interesting video as usual .
FSRs are employed in modern electronic drum kits, not as triggers, but in HiHat pedals as a means to sense the degree to which the two ecymbals are open or closed.
Incidentally Ken, are you planing on doing any forth based videos using analogue inputs or OLED displays?
I'm currently experimenting with "Punyforth" which supports the ESP8266 range of boards and wondered whether you have tried this implementation of Forth and if so, your opinion on it.
Regardless, keep up the good work !
Thanks for the response. I am aware of Punyforth but have not used it. It seems to be getting popular as is ESP32/8266. There is a Forth website that covers Forth code for SSD1306 Oled displays. arduino-forth.com/
I am hooked on using my smartphone as a display for many of my projects. You just have to plug in a HC-06 module and its wireless. ua-cam.com/video/_5g5lC-nDy8/v-deo.html
For product development an OLED is the way to go.
Thanks for the video. I have had a stroke and my right foot doesn't move as fast as it used to. Making a drum trigger with an FSR could be an excellent option for me. I have a couple of questions, if you wouldn't mind. What is the peak voltage in the first FSR you've shown? It looks to be around 1.1v to 1.5v. Is that accurate? Also, what is that voltage dip after the FSR is triggered? Thanks in advance for your help.
The circuit was powered by 5 volts so the peak output was around 3 volts. The waveform is a basic RC differentiator output. You will have to check what your drum controller is looking for as a trigger. Some will take a piezo pad directly and others need additional signal processing. Here are some links on RC circuits and force sensing materials.

Thanks for the quick reply and for the link. Now I see on the scope where it hits 3v.
Great, sir one question : I have a drumpad that uses FSR and I want to replace them with piezoeléctric how I do it, I tried but I'm getting errors when I hit hard one Piezo it triggers others midi keys, AND the volume Is unstable, I have just conected the Piezo directly instead of the fsr, any ideas?
If your drum controller is designed for FSR trigger inputs, using a Piezo pickup may not work A FSR changes resistance as oppsosed to a Piezo pickup that changes voltage.
Check your user manual for more info.
Can it be midi velocity sensitive?
map the output voltage (0 to 3v if Vcc is 5v) to 0-127 velocity and add either (1) a waveform generator code snippet or add MIDI output to your code to send a MIDI note/velocity based on the mapped voltage
what is that breadboard???
The breadboard is Super-Strip by AP products which was introduced in the early 80's and is no longer available. It had gold plated contacts and came with a lifetime warranty.
Hai master does it work to a drum module,😅😅😅
Yes .. if it has external trigger inputs.

Can the author of this post contact me dm?
Ah yes the yamaha dd-55 haha
Interesting !
