In the tracks that I use for my vocal and old time music samples, I use the excellent free plug-in SupaTrigga, which slices up audio and then rearranges, reverses, slows down or silences the slices based on various probabilities. I’ll momentarily turn it on with a MIDI button for a blast of glitchy goodness.
I set it up like this:
The key parts of this setup are:
Granularity is set to 16 slices/ measure. While this is by no means the only setting that produces good results, I find that 16th note slicing provides the best results across the widest variety of contexts.
Rearrange is set to 100%. This means that the audio is rearranged as much as possible. When I hit my Supa Trigga button, I want a dramatic effect – immediately.
Reverse is set to 5%. A little reversing sounds really cool, but too much of it can produce really chaotic timing. I want rhythmically tight glitching that sounds good when looped (more on this later).
The other settings were arrived at by experimenting. The probability that a slice will be slowed down or repeated are both at about 30%, while silencing is turned off (set to 0%) because I found it to produce too many rhythmically awkward results.
