Teenage Engineering Choir Olga Russian Contralto

Teenage Engineering's CH–8 Olga is a solid beech singing doll that functions as a standalone generative synthesiser and MIDI–controlled voice module. The Russian contralto occupies a unique category: sculptural instrument and functional audio hardware merged into a single object. Each doll in the eight–piece choir ships with an embedded speaker module, pre–composed vocal material, and wireless connectivity to chain multiple performers together or integrate with external controllers.

Olga measures 200 mm tall and weighs 696 g, with an internal driver capable of 3–4 hours of continuous singing time per charge. The contralto vocal range sits distinctly in the lower register. MIDI control links via Bluetooth Low Energy to any standard keyboard, the OP–1 Field, OP–Z, or an Ortho Remote for playback management and level adjustment. Wood grain patterning varies per unit, making each doll visually distinct. The form factor allows tabletop placement, integration into modular setups, or use within ensemble configurations supporting up to 15 concurrent voices.
