Short stabs on a scale c,d,e. . . To. . G,a,b. Fm synthesis. One sinewave oscillator output gets mashed by a another that's outputting a triangular wav. The oscillators are fed back into themselves and each other and 40 voices unison added to create a ubiquitous growl/yoy sound. On large speakers, or a decent pair of buds, the sinewave osc fundmental can be heard as sub-bass. Flstudio was used to host the synthmaker vsti oscillators and render the wav file.
