Patch Description

The control part of this patch uses the six Quantussy Cells in my DIY Quantisise, plus an additional cell made out of a Serge Positive Slew and a Serge Smooth & Stepped generator.  The Positive Slew cycle pulse is self patched to its Sustain input to make it self-cycling.  This pulse stays high when the ramp is greater than zero volts and makes a very short pulse at the end to start they cycle over.  Such a short, negative pulse is perfect for patching the SSG Hold input to make it into a sample & hold.  The two halves of the SSG are acting as S&H.  This cell is patched into a cycle of the Quantussy cells to make a seven-cell circle.  A second Positive Slew stands by itself as an LFO.  Each Positive Slew triggers a Serge VC Envelope Generator at the end of its cycle.  I also use those same pulses to trigger two Serge VCFQ filters.

Two stereo sounds are generated.  One is the pair of bongos made by triggering the VCFQs.  The other sound is processed noise, gated by two VCAs controlled by the two envelope generators.  A switch selects between white and pink noise.  The selected noise is modified by parallel signal paths, one going through a Serge Resonant Bandpass filter bank side (one half of the bank), the other through a Serge VC phaser.  These signals are mixed into a Bugbrand Frequency Shifter and on to the output mix.

Here is a short example of the patch running by itself.

Now here’s the actual performance recording.  I used the Boss RC-1 loop pedal to make overlays.  The initial loop is 30 seconds long. Thereafter each new 30 seconds of generated sound is overlaid on what came before.  The result is a gradual buildup of density over 12 minutes.  At the end there are 24 overlays.
