Velocity Sensitive Drum Trigger from Old Headphones

Step 6 Install Software

KTDrumTrigger
A plugin that triggers MIDI notes based on the sound level of the incoming audio stream in different frequency bands. It allows you to "detect" occurrences of percussive sounds in an audio stream and send out a MIDI event whenever that happens. Available as VST effect for MacOSX and Windows.

Virtual midi cable program ( MIDI Yoke or Maple Cable)

You can use Ableton, Cubase, Cakewalk, Fruity Loops, etc. to run the VST
OR
a Stand Alone VST Host. I suggest SAVIHost

-
Set the Midi Out of SAVIHost to Midi Yoke 1. Then in your audio app, set Midi In to Midi Yoke 1.

In the Wave Devices settings of SAVIHost set the Input port to your mic input.

In KTDrum, make sure you set the Threshold and Gain of the Trigger 1 high enough to trigger events, but not to low enough for ambient noise to set off.

Have Fun and make Great Music!

Can somebody tell me is it possible and if it is 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 "drum."

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?

[cheft]

Trying to get a video camera, but not soon, sorry. Would an sound capture help?

[elbandito]

Sound capture would be good... I'd like to hear how you've incorporated it into actual musical use. Thanks for the instructable!
