Antares Harmony Engine

Antares Harmony Engine: The 4-Voice Vocal Harmoniser

Antares Harmony Engine is the professional 4-voice vocal harmoniser that produces natural-sounding harmony vocals from a single input lead vocal. Rather than recording every harmony take separately, Harmony Engine generates up to four independent harmony voices that can be mixed, panned, formant-shifted and MIDI-triggered for full backing vocal arrangements from a single vocal recording. The same Harmony Engine technology powers the Harmony Player inside Auto-Tune Pro 11, delivered here as a dedicated standalone plug-in.

What’s Inside Harmony Engine

• Four independent harmony voices: each with individual pitch, mix, pan and formant controls
• Chord recognition: analyses input source or MIDI chord track to determine harmony intervals
• MIDI-triggered harmonies: play harmony pitches from a MIDI keyboard or piano roll
• Scale-based harmonies: set root, scale and interval offsets for automatic harmony generation
• Formant control per voice: shift voices to sound higher, lower or same-gender for realistic arrangements
• Vibrato control: add natural vibrato to harmony voices for realistic performance feel
• Humanize function: micro-timing variation preserves natural performance character
• Real-time performance: low latency for live-sound and tracking session use

Frequently Asked Questions

Is Harmony Engine included in Auto-Tune Pro 11?

The Harmony Engine technology powers the Harmony Player inside Auto-Tune Pro 11. The dedicated standalone Harmony Engine plug-in delivers the harmoniser as a separate insert plug-in with additional MIDI control depth. Producers who use harmonies on many tracks find the standalone workflow faster. Producers who occasionally add harmonies inside Auto-Tune Pro 11 sessions may not need the standalone.

Does Harmony Engine work with MIDI input?

Yes. Route a MIDI track to Harmony Engine and play the harmony pitches from a MIDI keyboard or piano roll. Each of the four voices can follow a separate MIDI input for detailed harmony arrangement.

Does Harmony Engine work on Apple Silicon?

Yes. Native Apple Silicon build. Runs on M1 through M5 Macs without Rosetta.
