Wave Replacement Synthesis Example: Analog Morphing which can allow ANY Waveshape
This is a visual and audio example of Wave Replacement Synthesis. Wave Replacement Synthesis is an analog technique which sounds similar to wavetable synthesis but uses only basic analog VCO's and VCA's. In this technique, any segment of one waveform can replace a segment of another. In this example, both waveforms are sine waves at the same frequency. Phase relationship is changed by using inverted pulse width to hard sync. Other waveforms or frequencies can be used. The window duration (or replaced section) is from a third VCO pulse width where its phase is also being controlled. These VCO's can also be freerunning for more fluid beating/morphing type sounds. Ultimately, you can voltage control any length of replaced segment (duration of window), position of the segment within the period (start point of window), and the segment you are replacing with (contents of the window). The window can also be called a slice or splice. Furthermore, this can be cascaded as many times as you have modules to do this with where any composite waveform can be made without any filtering. My blog talks about this concept several times, beginning in 2012 and you can see the basic patch diagram here.
