Harmonic Content Morphing (HCM) Synthesis is based on a large and expandable repertoire of standard waves like saw or pulse as well as complex waves like multi waves, trumpets, organs, pads, pianos, and voice samples. These waves can be modified in real-time by, for example, transposing the wave by one or two octaves and adding it to the original wave, altering its harmonic structure, syncing, compressing or expanding the frequency domain of the spectrum, making the wave fat using only one oscillator by transforming each wave into a hyper-wave, selecting some cycles of a sample and moving through them over time (comparable to wave-table synthesis). Any modification of a wave can be modulated producing lively shimmery sounds. In total there are more than 14,000 different spectra available for combination and modulation.
