Instruo Troika Black (USED)
troika is a set of 3, all analogue, voltage controlled oscillators in a single module.
They can be used individually or summed with a built in mixer.
Each of the voices generates the classic waveforms and use a unique control set of switches and crossfaders for truly analogue crossfading between wave shapes.
Between the three voices, crossfading between any combination of classic wave shapes can be achieved. In addition, the third voice has PWM capabilities.
