With a little software and some stuff you have around the house, you can make a simple drum trigger. A fancier version would use a real drum pad, a piezo transducer, and a cord with a headphone-jack; but this can literally cost you nothing to play around with.
Using a free VST app you can use the mic in to control MIDI events. It can be used to control drum machines or simply trigger samples.

set of old headphones (only one side needs to work)

one could use the circuitry of a usb keyboard to give different signals to the pc... with a soft like hydrogen witch is free.. a suggest the puppy studio, a linux distro aiming for sound creation with real time kernel.. it already comes with qwerty to midi in hydrogen, u just have to press the key.. with a lot of well known drum kits, like the tr808 and tr909 and so on.. u can use your own samples and it runs from a cd or flash pen, don't need to install it.. give it a try.. I'll do something like an diy akay mpc out of legos.. hope it will work, it will be my first project.. <br><br>http://www.linuxmusicians.com/viewtopic.php?f=4&amp;t=6994<br><br>should also read:<br><br>http://www.jackaudio.org/<br><br>http://www.instructables.com/id/Hacking-a-USB-Keyboard/<br><br>http://www.hydrogen-music.org/hcms/<br><br>god work, hope u enjoy it..
yes this is exactly what i want to do. it would have to a usb keyboard though? couldn't i just switch a ps2 end for a usb somehow?
view my instructable:- <br> <br>http://www.instructables.com/id/WORLDS-CHEAPEST-VIRTUAL-DRUM-at-10-Rs500-us/meta-stats
Yes U could, I know ppl do it, but don't know how....<br><br>please see this...<br><br>http://www.youtube.com/watch?v=c-riedhAs4g<br><br>from my undestanding, with software like drumagog u can use like 1 mic and a pair of small headphones, or maybe two sets of headphones.. plub one in the mic slot and the other one (I suposse) in the signal in, with the vst U can trigger one diferent sample on each chanel.. with velocity sensitivy and all.. the problem is the price of such vst...<br><br>there are free alternatives, like this one: http://www.kvraudio.com/get/2117.html<br><br>only 3 frequencies (Low,Mid,High).. I'll try some day to do an airdrum like that guy..<br><br>try to search the free alternatives in the <br>http://www.kvraudio.com search for trigger and see whats free and hot..<br><br>Good luck..
Sorry about 1 thing.. I suggested U the same vst that U used in Ur instructable.. sorry.. It works with bass, midle and high, so I suposse if U wire 3 piezzos with diferent material covering it, producing distintal frequencies, in theory should work....

sorry for my english.. im portugese..
is there some way to make more than one and assign midi cc numbers to each one? how does one from the store work with multiple pads and using a midi cable?
ok well im quite confused how the whole thing works?
You are turning and old broken pair of ear-buds into a microphone, then using software to translate that into midi with velocity. <br />
ahh :L thanks and wel i know alot of people have been asking this but is there any way of having both headphones work as 2 pads?
Not with this software. You'd have to pay for something like Drumagog.<br />
Can somebody tell me is&nbsp;it possible and if&nbsp;it is&nbsp;how can I connect more than one drum trigger (I want to make a drum kit) with my computer but without using a drum module?Please tell me if you know!
Use a rock band type game controller then, this will only handle one &quot;drum.&quot;<br />
if i have 2 working speakers...... can i make 2 pads then?
Only if you could get them to produce different frequency inputs - you might be able to do that by changing the type of foam, making it harder or softer, or thicker or thinner..<br />
Work you harder.&nbsp; Make you softer. Do it thicker. Makes us thinner.
if i have 2 can i hook them up so ill have a trigger machine with 2 or more buttons?!
How would this work with larger speakers? say, PC speakers? I'll try it.
Cheft, nice project, I'll definitely be mucking around with my own this weekend! Now, I know KTDrumTrigger is a mono-in plugin, but I'm thinking couldn't you use two instances of it (ie - two audio tracks, each with KTDT, with KTDT's MIDI going from both into one sampler/drum machine/whatever - I've not used KTDT in a long time but I dunno if you can do that or if you'd have to have each instance on a different midiyoke: either way you could easily bus them together and send them both to the same instrument in most DAWs) and use both headphones, making a second trigger with the other phone (and probably making them both a little smaller, so there's less risk of crosstalk) and then sending (in your DAW) the left headphone to the first audio track and right to the second, and... voila - two triggers, allowing kick/snare, or closed/open hihat control... That ought to work, right?
i got it i got little sounds getting out of it, but is not loud enogh en how t5o i do a drum soud to it like the snair drum of something ?
You're supposed to use KTDrumTrigger to generate MIDI data, which you send to a sampler or drum machine virtual instrument, and have that set to play back drum sounds - it sounds as if you're just recording the audio input, and you'll have a hard time making that sound anything like a drum!
Wow that's some real ingeniuty, could you show how it operates in a video?
Trying to get a video camera, but not soon, sorry. Would an sound capture help?
Sound capture would be good... I'd like to hear how you've incorporated it into actual musical use. Thanks for the instructable!
lol, i figured it out. i was being stupid. i got vst host.
question. i downloaded ktdrum from the link you gave us(both the .exe and the zip) but neither had somthing i can run. -just some.fxb's some internet shortcuts and a pdf. how do i get to the program you were using in the picture?
Do you need a virtual MIDI cable software? Because I have Ableton but it's on a Mac.
Unfortunately, KTdrum is for PC, But yes you can do something similar. Search for an Audio to MIDI program that will use live sound. Load the VST in Ableton and set inputs then JAM!
cool thanx cheft!
nice idea!
