Making a Roland Drum Trigger

[@GeorgeTsiros]

keep in mind a hard hit will kill the piezo How hard? I don't know, but they do have an upper limit. If you hit a piezo with the stick _directly_ it will just kill it immediately. With the cork and whatnot, it will be much, muche (muche? muche.) more resilient though.

[@Melkor0410]

I have an understanding on wiring. To make things easier. Lets not wire a guitar cable here but simply an input jack Piezo hot wire to hot of input jack Piezo ground to ground of input jack So that way its like any other drum trigger where you could just plug in and plug out.

[@AnderMalkus]

I didn't realize you could use that disk think as an input, I took apart an old alarm clock from a thrift shop and that looks like the device for the speaker/alarm. Very cool!

[@rm2kdev]

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)

[@TheKingBJ]

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

[@FrannB]

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

[@drummickey1598]

thats awesome... I wanna use your tenhnology for my drums. I respect you.

[@nutsandy7183]

That works and sounds better than the proper ones!

[@rm2kdev]

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

Hi could you post a video with an improved version that you were talking about in this video

[@FrannB]

Very nice video, btw, can a faulty piezoelectric damage the e drum module?

[@FizzlNet]

Nice! I want to try this. Just got an Alesis e-drum set. The module has two available inputs still. Do you have a link where I could get a suitable piezo transducer? Also, is there some standards documentation available for e-drum interfaces overall?

[@rm2kdev]

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.

[@audionerd8821]

@@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.

[@FrannB]

@@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?

[@audionerd8821]

⁠@@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.

[@RyanMarchand]

How long did it honestly last for? I've been having g trouble getting soldered connections to piezo discs to be hearty and welded like I can do with microphone and patch cables

[@homeofdiy2023]

Amazing work

[@nicoacevedo5203]

This could work for my pad roland spd sx?? I have to do some extra settings or is just conect and play?

[@paulyates5092]

Why use a stereo TSR jack for a 2 wire piezo disk instead of a TS jack.

[@audionerd8821]

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.

[@cavanimakesthenoise]

Hello,so nice,it is what I was looking for. I kindly ask: with this method,can I reproduce all the drum parts?tom,snare,ecc? Instead of cork,can I use a more strong piece of wood?The piezo will work fine the same?Thanks so much.

[@TheKingBJ]

Yes yes and yes

[@sebastianandrescastroviver268]

Hello, I plan to create a drum trigger, but I need it to control a drum machine (which only has a midi input), do you think I can create a drum trigger that instead of a jack has a midi input?

[@MattMcConaha]

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.

[@AbelsColdSweat]

Amazing! How does it detect your mashing of the sticks around the whole cymbal instead of on that small sensor?

[@rm2kdev]

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.

[@dennisneo1608]

Edrums are so easy to make.

[@brianwilson7928]

Not quite a roland trigger but cool nonetheless 👌

[@stevenb1234]

Please please make some more 3d printer videos please

[@taharamyth1790]

Play video games again

[@dietrichdietrich7763]

Lol not bad

[@johneeadbl5876]

Can you say "pie" (long 'I') + "ee" (long 'e') + "zoh" (long 'o')? 'piezo' is properly pronounced: pi ("pie") + e ("ee") + zo ("zoh")!

[@reddcurry]

No, it's not.

[@johneeadbl5876]

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

[@reddcurry]

@@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.

[@makers_lab]

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.
