Oboe is small language for designing synthesizers. The current back-end targets Csound, in the future SuperCollider may be supported.
Oboe aims to overcome the poor support for modularity in the current generation of synthesizer design languages (Csound orchestras, SuperCollider synthdefs) and offer properly reuseable, nested components not just a single strata of components (ugens).
Oboe is a revision of my previous synthesizer design language Ochre. Ochre used traits to compose synthesizer components. Composition in Oboe uses forms (extensible records - c.f the languages Piccola and GLoo) which seems a better fit as Oboe is roughly a functional language.
