Tunix

Automatic Pitch Correction + Harmony

Real-time pitch corrector and harmony for vocals — from natural, transparent correction all the way to hard robot snap. Tunix locks your voice to any key and scale (or the MIDI notes you play), preserves its natural formant character while it retunes, and stacks up to three scale-aware harmony voices. Add a doubler, dual-LFO modulation, and an automatic ducking wash, and you have a full vocal chain in one plugin.

FEATURES

Lead Pitch Correction

◆Low-latency time-domain PSOLA corrector you can monitor through live — no distracting lag while you sing
◆Retune Speed (0–400ms) from invisible natural correction that keeps human drift to a robotic stair-step
◆Strength controls how hard each note is pulled onto the scale; Hard Tune is a one-toggle hard-robot snap
◆Throat / Formant shift (-12 to +12 st) plus Formant Preserve so correction never chipmunks the voice
◆Anti-Warble median pitch pre-filter rejects single-frame octave-jump glitches on breathy attacks
◆Sibilance Protect leaves consonants un-smeared; Low Cut and Ref Tuning (430–450Hz) keep the detector honest
◆Struggle dials in a controlled pitch-glitch "yodel" that bubbles between adjacent in-scale notes

Key, Scale & Detection

◆MPM / NSDF real-time pitch detection with an octave guard, hysteresis, and a voiced/unvoiced gate
◆Automatic Key Detection (Krumhansl-Schmuckler) picks the key for you, or set it C through B by hand
◆9 scales — Chromatic, Major, Minor, Dorian, Phrygian, Mixolydian, Harmonic Minor, and major/minor pentatonics
◆MIDI Mode: play the correction target note from a keyboard instead of snapping to the scale

Smart Harmonizer (3 Voices)

◆Scale-aware diatonic harmony voices that always stay in key — even odd intervals land consonant
◆21-cell harmony matrix: per-voice Interval, Level, Pan, Formant, Detune, Vibrato, and Humanize across 3 voices
◆Formant-locked shifter per voice with a 5ms anti-click gate on every voice on/off
◆MIDI / Chord Mode — hold a chord and the 3 voices follow the held notes as an input-following choir

Modulation, Width & Wash

◆Dual-LFO modulation — Sine/Triangle/Square, free (0.05–20Hz) or tempo-synced, routable to Pitch, Formant, or Pan
◆Doubler — dual micro-detuned, short-delayed copies panned hard L/R for instant thickness
◆Dimension Widener with the centre anchored to the dry so the mono-sum never collapses
◆Ducking Wash — a lush parallel reverb + delay that ducks under the vocal (Ghost Kick or Vocal source) with Size and Pump, and blooms back in the gaps
◆Build-Up / Rise — a tempo-synced performance riser over 1–32 bars for drops and transitions

Polish & Output

◆De-Esser — dynamic 5–9kHz sibilance taming on a per-channel band-pass sidechain
◆Equal-power Mix against a latency-aligned dry (no comb), Output trim (-24dB to +6dB), and a gated Bypass
◆Constant pinned latency that never re-syncs the host PDC, with a DC blocker and a 0 dBFS true-peak ceiling
◆Piano-Key Lane display with live detected and corrected pitch dots, a cents meter, and a voiced indicator
