The Instruo Troika Eurorack 3-Voice Analogue Oscillator offers 1V per octave with coarse and fine controls, and individual oscillator outputs. The Troika is an arrangement of three all-analogue oscillators that can function completely independently or together via parallel pitch tracking.
The Troika was designed to simplify the patching of layered voices in this manner with the benefit of having three voices with matched components and calibration for consistent pitch tracking. The oscillators each have linear FM inputs with attenuators as well as oscillator sync inputs. This allows for FM operator configurations with first order and even second order modulation on a single module.
Sine, triangle, sawtooth and square waveforms are generated from each oscillator voice, except for oscillator three, which lacks triangle but gains CV controllable pulse-width modulation over it’s square wave. Each oscillator has a level control, with the summed output available at the Mix Out.
