STG Soundlabs has been working on these relaxation core oscillators for a couple of years and has them ready to ship in differently styled MU and Eurorack formats.

Relaxation Core Oscillator

You don’t hear the term “relaxation core” very often but it refers to a nonlinear electronic oscillator that produces a nonsinusoidal output such as triangle, sawtooth or square wave which is precisely what we have here. The main waveform outputs are sawtooth and triangle whereas the square wave is a sub-octave output.

To relax things even further it has a built-in Drift Generator which introduces what they call a bit of random wobbulation. It’s a bipolar linear function generator with smoothing which gives the output a bit of character and quirk. That’s a really nice touch. It’s also normalised to the modulation input and is bypassed when you plug in another source of modulation.

The tuning system is a bit unique in that it uses three controls: Range, Semitone and Detune. The Range sets it from LFO frequencies up through 5 individual octaves. The Semitone knob steps between semitone divisions within the octave whereas the Detune knob then dials in between the steps. Another nice touch is that the root, fifth and octave all have double the rotation degrees on the turn of the knob to make them easier to find. With the Range knob set to “Wide” then the Detune knob can sweep through all 5 octaves.

The Oscillator is available in the MU format in traditional black styling for $295 or as a silver Eurorack version called “.VCO” (dot-VCO) with fruity purple knobs for $265.

It feels like a lot of thought has gone into offering an oscillator with some interesting character and usability. The same could be said of their 1998 style website.
