Making a Roland Drum Trigger 

Yeah man these when you run electricity through them they buzz (alarm) and when you tap or vibrate them they generate current :p (which can be sensed by a drum module)

You can buy em new for less than quarter of a dollar in any electronics shop They can be an alarm buzzer, a contact microphone and this

You seem to know about e drums, can a faulty piezoelectric damage the e drum module?

Thanks man yeah it does a decent job :p now I have to figure out how to make it a bit more refined looking with proper mounts and get it on the kit perninantly

Concur

Sorry mate, i did reply to you for some reason it didn't save :o! Long story short i said that i put the link in the description of the video and as for standards there is no real standard i think each module does it their own way i would recommend searching for on google "Alesis Drum Trigger Wiring Diagram" and you'll most likely come across some.

You seem to know about e drums, can a faulty piezoelectric damage the e drum module?

@@FrannB I don't see how it could. It has no active electronics. Its an analog signal so if its too low of a level or not passing signal because of some type of fault then there wont be an output signal to trigger the input of whatever you plug it into.

@@audionerd8821 Ok thanks, btw, can I do what the person did on the video with a stereo jack input too? or it has to be mono?

⁠@@FrannB​​⁠​⁠TRS connectors can be either mono or stereo. Depends on what you are wiring. In this case its a mono un-balanced piezo so it only has a hot and cold, no ground. So he wires it : tip is “Hot” (red) Sleve “cold”(black) He could have used a TS and it would be exactly the same.

Maybe thats all he had at the moment. In this case it wont make a difference as long as he wired it correctly which he did.

It is worth noting that this system outputs an analog signal according to the vibrations detected by the sensor. The Roland drum computing module then somehow converts this analog waveform into drum sounds. This makes the whole process pretty simple, the Roland hardware does pretty much all the heavy lifting. If you are talking about a midi input drum machine, you need to be able to output a digital midi signal. So you will need a processor which is programmed to parse the analog signal to detect the timing and velocity of your strikes and then send out the appropriate digital midi signal to the drum machine.

Yes yes and yes

The piezo is glued to the Cork so the vibrations transfer through it anywhere you hit :) ofcourse hitting on the sensor its self is more senative but it will still register anywhere you hit.

No, it's not.

@@reddcurry yes. It is. Look it up in an offline dictionary.

@@johneeadbl5876 why would I look it up in an offline dictionary?! It's a word that comes from Ancient Greek, and it's original pronunciation is closer to what he uses in the video. I've heard both pronunciations being used. However, it's NOT properly pronounced as you say it is.

Now now children, and FWIW, usual way is “pea”-“zoh”. But let’s appreciate just how well this works and how muted the pad noise is compared to the pro ones.
