Microsound: advanced granular, pulsar, and particle synthesis
Learning objectives
- learner can use advanced granular variants — synchronous/quasi/pitch-synchronous, glisson, grainlet, trainlet, pulsar — for specific textural goals
- learner can compose across micro-to-macro time scales with micromontage and multiscale organization, treating grain-level choices as compositional
- learner can apply the granular paradigm as a resynthesis framework — re-granulating existing material via higher-order granulation, and grounding structural description in the Gabor/Xenakis particle view of sound
Capstone — one whole task that evidences the objectives
Compose a 30-second microsound study: generate clouds with two different particle techniques (e.g. pulsar and glisson), derive at least one further cloud by re-granulating an already-rendered cloud (higher-order granulation), arrange them all as a micromontage on a timeline, and articulate the meso/macro structure in terms of the granular paradigm (Gabor's sound quanta, Xenakis's screens).
Prerequisite modules
This module builds toward composing a complete microsound study — the kind of piece you hear in Curtis Roads’ own catalogue, in glitch and clicks-and-cuts records, or as the textural bed under an ambient live-coded set. In real practice the payoff is a rig-independent skill: whether you work in a SuperCollider buffer, a Max patch, or a DAW with a granular plugin, you stop treating the granulator as a preset effect and start treating individual particles as compositional material.
The arc runs from supported experiments to the unsupported capstone. Start by drilling the rhythm-to-pitch transition of synchronous grain streams until sweeping density feels like playing an instrument, then branch into the particle zoo: pulsar synthesis for vocal-like formant tones with independent fundamental and formant control, glisson clouds for chirping swarms, trainlets and grainlets for buzzy and parameter-linked variants. When artifacts bite, “Pitch-synchronous granular synthesis aligns grain envelopes with the waveform period” is your JIT fix. Higher-order granulation is not just a fix but a capstone requirement: re-granulating an already-rendered cloud is how the study exercises the granular paradigm as a resynthesis framework, spawning new mesostructure from old material. The studio-montage workflow — render clouds offline, then arrange them on a timeline — is the bridge exercise that becomes the capstone itself.
The required atoms gate the capstone directly: you cannot arrange a micromontage without two particle techniques in hand; you cannot derive the re-granulated cloud without higher-order granulation; you cannot articulate meso/macro structure without the multiscale-composition atoms that explain why grain-level choices propagate upward into form; and the paradigm-grounded structural note draws on Gabor’s quanta, the Gabor matrix, Xenakis’s screens, and the universality of the granular representation. Supporting atoms enrich rather than gate — dictionary pursuit and concatenative synthesis extend the resynthesis idea toward analysis-driven workflows, spectromorphology and felt texture vocabulary sharpen how you describe the study’s motion, per-grain spatialization and harmonizer techniques open transformation paths beyond the timeline montage, and the virtuosity and time-reversibility atoms deepen judgment about performing and transforming the material.
