NORTHFX TWIN vocal doubler: One voice. A whole session of takes.

TWIN / IN ACTION

See it. Hear it.

Singers, not a chorus effect

Up to 8 virtual singers bring independent timing, pitch, vibrato, scoop and voice size. Timing moves from syllable to syllable by moving the voice itself, without delay modulation that makes the pitch wobble.

CROWD moves from a tight double to a full crowd. Above 50%, each singer adds a second drifting take on the opposite side. Choose unison, octave up or down, third above or below, fifth above, or whisper. Harmonies follow your key and scale.

Build DOUBLE, STACK, HARMONY, CHOIR or WHISPER in one click while keeping your humanize settings.

Tight where it matters

Tight Consonants locks word starts to the lead while vowels remain loose. De-S Doubles leaves S and T sounds with the lead; Tight Ends brings the doubles to a clean finish.

Double Gate lets doubles sing always, on held notes, on loud parts or only on accents. Lead Focus makes room for the lead’s consonants and accents, then fills the gaps.

Real Double & Take DNA

Send a real double to the sidechain. Align corrects timing outside your chosen tolerance; Pitch Align gently pulls nearby notes toward the lead.

Take DNA learns the double’s average timing, timing spread and intonation. Your virtual singers can inherit that style, and the DNA is saved with the session.

Built for the session

Variations follow song position and a TAKE number, so playback and bounce match. Stack compensation keeps the overall loudness similar as you add singers.

Tempo-synced Width Motion, Whisper Layer and Air add movement and breath. Mono Check shows correlation and mono loss, warning when doubles lose level in mono.

MUTATE creates new singers and a new take, with locks for humanize, voices, stereo and consonants. 22 presets cover Pop, Rock, Rap, Trap, R&B, Hook, Choir, Harmony, Character, Motion, Real Double and Mono Safe.

THE INTERFACE

Built for the session.

Five focused pages with live feedback: see every singer on the stereo stage, watch the timing lanes move with each syllable and check mono compatibility while you work.

STAGE: every virtual singer on a stereo stage, each with its own timing lane.
