The Jerkster Chaos Circuit<\/a><\/p>\nI’ll soon publish photos of this module.\u00a0\u00a0 The first interesting patch I’ve created with it is demonstrated in this recording.\u00a0 You are listening to a collection of modules set up to create a random harmony, using the CGS Infinite Melody, two MOTM-310 VCOs, two MOTM-440 filters.\u00a0 The Modcan Dual Quantizer keeps it on pitch, and the Dual Oakley ADSR-VCA modulates the notes.\u00a0 All of that is pretty standard.\u00a0 The interesting part is what the Jerkster does:\u00a0 First, it provides a chaotic vibrato applied to the filters.\u00a0 The X and Y outputs (which look fantastic on the Veeblefetzer displays) are used for these.\u00a0 The Z output is patched to a comparator to produce a random trigger for a sample and holds that also modulate the filter cutoff frequencies.\u00a0 The random trigger is divided by factors of three and four to gate the envelopes.\u00a0 The Jerkster is itself controlled by a third sample and hold.<\/p>\n
This is unusually mellow for a chaotic patch.\u00a0 Realize that the chaotic aspect of it is in controlling the rhythm of the notes, as well as in the varying vibrato.\u00a0 This is aleatoric and runs without intervention.\u00a0 You hear one of the many scales available from the quantizer.\u00a0 The 5th-Octaverb effect from the MPX-1 is used here, as well.<\/p>\n\n\n
