It is available as a demo version within the software; however, it must be purchased separately (or bought in the FL Studio All Plugins Edition bundle) in order to save projects that contain Harmor instances.

Imported audio (WAV, AIFF, WavPack, MP3, OGG, REX1&2) and image (.bmp, .jpg, .png, .gif) files can also be resynthesized quite faithfully, and some of their parameters can be edited such as time stretching, pitch shifting, and formants, in addition to the full amplitude, pitch and phase harmonic-level manipulation enabled by the additive parameters described above.

Harmor’s spectrogram (visual feedback panel) can also be revealed to show partials sent to the synthesis engine and display their behavior in real-time.

Although Harmor is internally an additive synthesizer, most of its controls found on the main GUI are presented in a way that is familiar to subtractive synthesis users.

[2] Starting off at the top left of the interface, two timbres, a saw and square wave, can be morphed or used independently when creating a sound.

Located directly below the blur module, the prism knob is the main way to control the pitch of partials, which is useful for creating a detuned or harsh sound.

By default, Harmor's phaser is essentially an endlessly rolling notch filter,[4] which can be extensively shaped, manipulated and even keytracked.
