Harmor is powered by an additive synthesis engine, similar to Image-Line’s synthesizer Morphine.Baer, David (September 2013). "Review - ImageLine's Harmor Synthesizer". Sound Bytes. Retrieved 16 April 2015. Although the different additive modules and controls found in Harmor can look similar to more conventional synthesizers that utilize subtractive synthesis, its sound generation engine differs in that it sums its partials later in the signal chain (right before the FX stage) compared to some other additive synthesizers. This means that the timbre, filters, harmonizer, phaser, equalizer, and more are all done additively. Furthermore, lots of these additive parameters can also be individually controlled per each unison voice, and the way these additive modules affect harmonics can often be changed according to custom shapes, masks, and harmonic distribution graphs in the envelope section using line editors. This enables a greater amount of harmonic control before partials are summed.
