<p>This cut procedure is derived from some analysis of the manic breaks work of Squarepusher, aka Tom Jenkinson. His innovation was to push the tempo range to around 200 bpm, and to create constantly varying beats with highly musical jazz inflected drum programming.
|
||
|
|
<p> His original work was with sampler/drum machine+sequencer but he uses many effects units and nowadays a laptop in his live shows. To my knowledge, all his programming is by hand, without algorithm. This is an automated routine inspired by his style, which is obviously my take on things and in no way to represent the great variety of great compositions Tom has created. The routine was inspired by transcribing drum patterns from Alive in Japan (disc 2, do you know squarepusher, warpcd97 2002).
|
||
|
|
<p> Note that the original Squarepusher material is created by specifying all the individual drum hits- this routine simulates that sequencing in one single line by cutting up a breakbeat sample, so it works on a sense of rhythmic aggregate, not an analysis of relative positions of kick/snare/hat. <h2><a class='anchor' name='classmethods'>Class Methods</a></h2>

<p>Use your rawest noisest breaks to hear this properly. You won't have all the breaks I use below. Start with something that is running quick so repitching doesn't cause too much chipmunkiness, or double the beats per sample value in BBCutBuffer.
|
||
|
|
<p>Otherwise you'll need to use CutBuf3 to preserve the original pitch and reslice. <pre class='code prettyprint lang-sc'>( //defaults
