Vocal Stutter

Inspired by HeadRush® Original

Divides the signal into rhythmic “steps”.

Repeats audio portions in sequence.

It can sync to BPM or work in milliseconds.

Includes modulations (pan, pitch) + freeze buffer.

Used for:

  • EDM/trap/glitch effects
  • live build
  • creative transitions

Control Parameters

SyncY/N
  • ON: synced to tempo (BPM)
  • OFF: free values ​​in ms

Determine how “Interval” works

Interval

Pattern base range

  • Sync = ON: musical values ​​(1/4, 1/8, 1/16…)
  • Sync = OFF: time in milliseconds

defines the “grill” of the stutter

Steps

Number of subdivisions within the range

Behavior:

  • a few steps → simple effect
  • many steps → complex glitch

More steps = more repetitions

Step Length%

Duration of each step compared to the available space

  • low: short cuts (detached)
  • 50%: balanced groove
  • high: more continuous sound

Control “how much” each slice sounds

Pan Mod%

Automatically modulates the stereo panorama

Effect:

  • 0% → mono
  • 50% → stereo motion
  • 100% → extreme ping-pong
Pitch Mod%

Modulate the pitch of the repetitions

Effect:

  • low → slight variation
  • high → glitch / tape effect / robotic

Create tonal movement

FreezeY/N
  • ON → freezes an audio fragment and repeats it
  • OFF → normal stutter behavior
Freeze Decays

Range: ~0 – several seconds

Loop freeze decay duration

Effect:

  • short → clean cut
  • long → dissolves gradually
Freeze VoldB

Signal volume frozen.

Allows you to emphasize or attenuate the freeze

Mix%

Blend between original signal and stutter

  • 0%: dry
  • 50%: parallel
  • 100%: effect only
Out BusMain / Alt

Effect output routing.

Useful for:

  • send separate glitch to mixer
  • controlled live effects

Quick Reference

  • Sync: sync BPM
  • Interval: cycle duration
  • Steps: number of subdivisions
  • Step Length (%): slice duration
  • Pan Mod (%): stereo movement
  • Pitch Mod (%): pitch variation
  • Freeze: audio block
  • Freeze Decay(s): fade duration
  • Freeze Vol (dB): volume freeze
  • Mix (%): dry/wet blend
  • Out Bus: exit routing
