Since 2024 it has made sound, code, text and image from Abya Yala, with eme in its direction. It treats computation as something that happens in a place, among particular people and histories, and asks what software, synthesis and listening become when they are thought from the Andes with their colonial histories in view. #### Ch'ixi The name comes from an Aymara word that Silvia Rivera Cusicanqui developed into a way of thinking about coexistence. A ch'ixi color is speckled: from a distance its points look gray, but the contrasting colors never fuse. The project's lexicon defines the term as differences that touch and pull against each other without becoming one substance, and uses it to decide how works, techniques and kinds of knowledge are placed side by side. Ancient and contemporary thought meet media technology on those terms. The lexicon holds forty-seven entries in which Andean concepts such as pacha and taypi sit beside neocybernetics, planetary computation, post-natural ecologies and sonic fiction.

NANAY, a group devoted to sonic demonology, released aputería, ¿Sueñan las bichotas con ovejas sintéticas? and ¿Es bala o pólvora?, which eme mastered at Momoto Studio. The Departamento de Exploración Ritmaquínica Interdimensional del Aka Pacha (D.E.R.I.A.P.) programmed the Pre-Tek series of recovered sonic artifacts. *un templo en las nubes del algoritmo*, by 4ndr0m3d4, is an exercise in post-digital mysticism built on a generative synthesizer that runs in the browser.

Caption: Release covers, 2024 to 2026: o, aputería, luna, ¿Sueñan las bichotas con ovejas sintéticas?, ¿Es bala o pólvora?, chinkay, Pre-Tek I and Pre-Tek II. #### Code Software belongs to the same practice. Ch'ixi Skills is a development kit that gives AI agents decolonial capacities through skills and rewritten agent identities, with methods drawn from ch'ixi epistemology and Rivera Cusicanqui's work. Anatman SDK examines the cosmological assumptions built into agent design, the values agents declare and where those values fail under conflict. Xynth is a drone synthesizer inspired by the Xyn of Reza Negarestani's *Cyclonopedia*; its web version ties sound parameters to activity on blockchain networks. aleph::ch'ixi was also the development and research platform behind Sonic Field Labs, and it builds AKOÚŌ, a multimodal listening system for agentic workflows.

In February 2025, Concierto Drone presented a quadraphonic set for gong and modular synthesizer at Persona, in central Medellín. Concierto Un momento was a deep-listening session under the dome of the Planetario de Medellín, made with Exploratorio and Éter Lab. Jornada Glaciar, in April 2025, gave a day to slow listening in the mountains of Santa Elena, coordinated with Coocine, Sonic Field, Éter Lab and Hábitat Sonoro, with performances, audiovisual works, conversation and a shared meal.

Tinkuy Orbital is its program of experiments with agents, where its own developments sit beside the writings of Don Hermes and the diary of mar, read from ecological, cosmotechnical and decolonial perspectives. A book-length essay in Spanish is in draft; it reads the colonial genealogies of listening together with planetary computation, sonic fiction and the engineering of agents. New releases, tools and performances are in preparation. Image: The aleph::ch'ixi homepage: the cover of Pre-Tek II, a coral square with an ornamental pattern, above the title in large serif type.
