![]() ![]() The beauty of this arrangement of five is that the cross modulations spiral around, resulting in unpredictable, but somewhat repeating patterns. Here’s the picture of it in the Audulus emulation. The Triangle wave of the first is sampled by the next, and then passed on to the CV input of the following one. Picture five of these, arranged in a ring, with each Triangle output patched to the Castle input of the next, and also the Castle output patched to the CV in of the next. So you can think of this as having a CV input, an oscillator output (triangle wave), a Castle input and a Castle output. The other sample and hold takes an external input and provides an output (Peter calls this the Castle). That is, every cycle, the oscillator can change its frequency, based on a sampled control voltage. One sample and hold is internally hooked to the frequency CV input of the oscillator. Each oscillator clocks two sample and holds. The Quantussy allows the cluster to be cross connected in many different ways, but the most interesting one is where the five are in a ring. Here, I want to focus on one main idea: that of a cycle of five cross-modulating oscillators. I wrote a full post about that schematic. I started digging into the Quantussy internals by studying the Cocoquantus schematic diagram. And this led me to build emulations of it. It does not use random functions! But, since it uses analog components with slight variations over time, temperature, etc., it is not fully deterministic. The Quantussy supports exactly this kind of exploration. The work of creating such sounds entails discovering, often by trial and error, the right combination of control and sound generating modules, and adjustments of their many parameters. I have an interest in generative music, automatically generated sounds that have the potential to seem as if they were intentionally composed, but in actuality are in some sense accidental, but not simply random. However, the applications can go far beyond that use! Generative Applications The purpose of the Quantussy is primarily to provide modulations for the two digital delays (COCO) in the Cocoquantus. The Quantussy petals can also run at audio frequencies, as well as “Balcium” frequencies, depending on a toggle switch. ![]() Running at low frequencies, the Quantussy is intended to provide ample modulations for the various functions of the COCOs, through inputs “FLIP”, “SKIP”, and “SP.AF”, or “Speed Affect”. The Quantussy is thus both based on five (5), but four(4)… and its name also refers to Quantum Physics through its unique “double quantizing” of angular momentum. The Quantussy is a five (5) petaled flower, each petal with oscirator, that creates a rhythm, that triggers quantizations of the movements of the other four oscirators. Quantussy is the name Peter Blasser gave to the cluster of five oscillators in his Cocoquantus. ![]()
