Oscar Tria Mk II: Triple mode, stereo VCO

At its core, Oscar Tria Mk II has 25 oscillators, all packed into 10HP. Each oscillator can be swept from sawtooth through triangle to square (with PWM). These oscillators can be used in three different ways.

A stereo swarm oscillator. 24 oscillators and a sub for a massive sound. Tria Mk II now offers control of the detune of the oscillators, from subtle to wild. Classic super-saws, ripping super-pwm pulses and ethereal super triangles, with everything in between.

A ‘traditional’ stereo VCO. Two main oscillators form a stereo pair, with a sub an octave below and a sub-sub two octaves below. One oscillator can be detuned up to an octave for subtle richness or fixed intervals, plus you get hard sync and linear, through-zero FM. Tria Mk II adds a new sinusoidal wave folder (with CV control, of course) for even more sonic shenanigans. The wave folder adds rich harmonics to the base oscillator. Changing the waveform (under CV control) and the wave folder at the same time sounds awesome!

Chord mode uses the multiple oscillators to create polyphonic chords. There are 20 chords available, and the chord type can be selected by CV – so a sequencer can produce anything from polyphonic pads to stabs. With Tria Mk II the chords can now be stretched over 5 octaves – and don’t forget that Tria Mk II is stereo, so you can still get those rich detuned sounds.
