Innovate

Playable examples of what you can build on the THIRI API + MCP. Prefer links on this page — they use canonical build.thiri.ai/innovate/* paths.

Full rack overview — five synth lanes with scroll-linked copy and MCP proof on the Studio page.

Csound instruments (drums, keys, band) are hosted on this site. Evocal harmonizer launches at demo.thiri.ai/demo. Practice tools (learn, solfege, tools) still redirect to practice.thiri.ai. If WASM fails to load, try a hard refresh or open thewoodshed.ai.
