In this video, I use only one kaleidoscope track. The note changes are generated by a step modulator, which modulates the oscillator frequency.
The timbre is a sawtooth. The filter with resonance is opened by a volume envelope in a cyclic mode. The envelope also suppresses the feedback of the comb filter. By adjusting the envelope decay time, we also control the strength of the feedback ducking.
During the video, I increase the FM synthesis level, overdrive, and feedback of the comb filter to radically change the sound.
