2 oscilators. One panned to the left the other to the right. High depth pitch bent on different rate speeds. With a modulator set to a certain frequency. And a delay over to give hi fi depth.
Simplest type of metric modulation in Bach. Slow introduction followed by Allegro, traditionally taken twice as fast. Eighth notes in the new tempo prepared by sixteenth notes in the old tempo ( = ).
Self modulating a standard doepfer a-110 vco. We are listening to a square wave. I'm modulating with a sinus. I'm wiggling pwm and the degree of self modulation (and attack and decay). Spring reverb and analog delay from stomp box.
Sequential modulation through the circle of fifths in Haydn, Quartet Op. 3, No. 3, IV, Hob.III:15 (now considered spurious, perhaps by Roman Hoffstetter).
