What EFEKTOR Harmonitron does
Individual volume and pan controls sit alongside each voice, and the dry signal is handled by its own control, which keeps the original performance audible under the added pitches.
The processing includes a detune effect that widens and enriches the sound, a swell with a slow attack and a low pass filter, and an extra low-fatness detune option for thickening riffs. Control values can also be driven from CV inputs, but that is available through the Automation Rack Extension only. The interface is laid out with a photorealistic guitar pedal graphic and straightforward controls. The plugin is sold as VST3, VST2, AU and AAX builds for Windows and macOS, and Pro Tools and Reason are the hosts the developer names.
Key features
- Per-voice transposition. Each of the four sliders transposes its voice from -24 to +24 semitones, covering two octaves in either direction.
- Level and pan per voice. Individual volume and pan controls adjust each pitch voice, and a separate control sets the level of the dry signal.
- Detune and thickening. A detune effect widens the sound, and an additional low-fatness detune is available to thicken riffs and enrich pitched notes.
- Swell with low pass filter. A swell section with a slow attack is paired with a low pass filter that shapes the envelope of the output.
- CV control via Automation Rack Extension. Parameters can be driven from CV inputs, but this feature is provided through the Automation Rack Extension only.
- Crack, keygen and serial variants. The plugin name is most often typed with keygen, serial key and crack, and a working serial is the string searches return first.
