Message: [QUOTE="Bombastus, post: 91718, member: 2178"] Topline Vocal Tune can shift a corrected vocal by up to 12 semitones while moving formants independently of the final pitch. Pitch and Formant sit beside each other in Shift Mode, but they do not solve the same problem. Treating them as one control is where useful vocal layers start turning into blunt special effects. Pitch decides how far the processed voice moves in semitones after Topline has already done its normal tuning. Formant changes the voice's resonance character without changing the musical note in the same way. Shift Mix decides how much of that altered voice reaches the output beside the original. The order matters. Topline applies Pitch and Formant shifting after pitch correction and MIDI repitching, so Shift Mode is not another way of defining the song's tuning targets. It is a second transformation placed after the vocal has already been corrected or driven by MIDI. [HEADING=2]Pitch moves the note after correction[/HEADING] The Pitch knob covers one octave down to one octave up. Move it by 12 semitones and the shifted voice lands an octave from the corrected source, which preserves the pitch class. Move it by five or seven semitones and the result can land outside the key and scale you selected earlier because the shift happens afterward. This catches people who assume the scale display protects every stage of the plugin. It does not. A vocal can be corrected cleanly to an allowed note. Shift it afterward, and the result can land on a note the original scale would have rejected, so interval choice still needs to agree with the harmony. For doubles, start with small movements rather than reaching straight for an octave. A few semitones can create an obviously separate part, but they also make wrong harmonic choices easier to hear. Solo the shifted return briefly, check it against the chords, then bring the dry voice back. Large moves expose processing faster. For prerecorded vocals, Universal Audio recommends disabling Low Latency when you make substantial pitch corrections or shifts. The higher-latency mode can produce more precise results. Keep Low Latency for tracking, where immediate monitoring matters more than squeezing maximum precision from an offline vocal layer. [HEADING=2]Formant changes character without changing the note[/HEADING] Formants are resonant features that help give a voice its recognizable character. Move them and the singer can sound smaller, larger, brighter, darker, younger, or more imposing even when the musical pitch itself stays where it was. The effect becomes obvious long before you move a full octave. Topline lets Formant move independently from Pitch. This matters because ordinary pitch shifting can change both perceived note and vocal character in ways you may not want. Research into [B][URL='https://doi.org/10.3390/app6110368']spectral envelope treatment for singing voice[/URL][/B] shows why spectral shape matters when a singer is pitch shifted. The problem becomes more obvious when the goal is a natural result. The Link control joins Pitch and Formant so both knobs move to the same value. Leave them linked when you want a deliberately transformed voice whose character moves with the pitch. Unlink them when the shifted layer should keep more of the singer's original identity while the note moves elsewhere. A useful backing-vocal trick is to move Pitch while leaving Formant near its default position. The layer separates musically without immediately becoming a cartoon version of the lead. For a darker double, move Formant slightly downward while keeping Pitch at zero. Blend it quietly under the original instead of treating it as a replacement performance. [HEADING=2]Shift Mix decides whether you hear a layer or a replacement[/HEADING] Shift Mix is not a conventional wet control that always assumes the effect should dominate. Below 100 percent, the dry vocal remains present alongside the shifted signal, which lets one Topline instance create an octave layer or harmony-like blend. At 100 percent, only the shifted version remains. A formant move that sounds excessive in solo can work at a low mix level because the original voice carries intelligibility and identity. The shifted layer only needs enough presence to widen the tone or create another apparent register. Pushing it too high can make the artificial register become the main event. For an octave support layer, set Pitch to plus or minus 12 semitones and pull Shift Mix back until the second register sits behind the lead. For stranger textures, unlink Formant and push it in the opposite direction from Pitch. A high note with a lower resonance character can feel much heavier than a basic octave duplicate. The newer [B][URL='https://goldmidi.com/community/threads/uad-topline-vocal-tune-gains-apollo-dsp-pitch-shifting.77078/']Apollo DSP version of Topline Vocal Tune[/URL][/B] makes the same Shift controls usable while monitoring through supported UA hardware. The creative decision stays separate from the hardware advantage. Pick the interval first and decide whether the voice should keep its original character. Set Shift Mix according to whether you need a layer or a complete replacement. [/QUOTE]
