Those are probably sequenced, and modified with some filtering/EQ.
You should check out virtual instruments like BT's BreakTweaker or iZotope's Stutter plug-in. Those will help you create textures such as Haken's.
Thanks! I will!
I use Toontracks' EZDrummer.
It's actual acoustic drum sounds which you can map out in MIDI.
Yeah, I use it too, but I actually referred to the effects more than the samples themselves.
You can achieve that by cutting pieces from the waveform, here's an illustration:
You'll have to zoom in quite a bit and make all that happen in a short period of time but that's it.
I think that's exactly what I was looking for. Thank you very much!
