Vocal Doubler

• Typical range: 0 – ±50 cents
• Function: Random pitch variation between voices

Behavior:

• 0 → all entries identical (useless)
• 5–10 cents → natural (study)
• 15–30 cents → noticeable chorus
• 40+ → detune / dissonant effect

It is the most important parameter for “realism”

• Function: speed with which the pitch varies over time

Behavior:

• low → slow variation (natural, human)
• high → fast variation (chorus/vibrato-like)

Technically it controls an LFO modulation on the pitch

• Typical range: 0 – ~50 ms
• Function: random delay between entries

Behavior:

• 0–5 ms → almost mono
• 10–25 ms → double realistic
• 30–50 ms → slap / chorus effect

Simulate the fact that no one sings perfectly in time

• Range: 0 – 100%
• Function: stereo opening of the voices
• 0%: mono
• 50%: moderate
• 100%: super wide

Increases the perception of "largeness"

Number of entries generated

Behavior:

• 1–2 → realistic double tracking
• 4–8 → vocal ensemble
• 12–32 → pad / “choir” effect

More voices = more density but less definition

Original voice volume (dry)

controls how much the main vocal stays in the foreground

Volume of duplicate entries

• balance effect vs lead vocal
• Similar to “wet level” in the plugins

Route the output of the doubler

Options:

• Main → main output
• Alt → alternative output (separate routing)

Useful for:

• send only the doubler to FOH/mixer
• create separate mixes live

(HeadRush allows multiple output routing) (InMusic Brands)
