Auto Swell

Auto Swell recreates the classic guitar volume-swell technique automatically, smoothing away the pick attack and letting every note bloom into a rich, bowed-style sustain.

Driven by transient detection, it transforms chords and lead lines into expressive swells, ambient pads, and cinematic textures—without touching your guitar’s volume knob.

• Time: Sets how fast the volume fades in after the note is detected. Lower values give a quicker swell, while higher values create a slower, more violin-like bloom.
• Sensitivity: Adjusts how easily the transient detector reacts to your playing. Increase it for softer picking, or lower it to make the effect respond mainly to stronger attacks.
• Fade: Shapes the swell curve for different musical feels.
  Linear gives an even rise, Log creates a more natural and gradual fade-in, and Exp delivers a sharper, more dramatic swell.
• Sync: Links the swell behavior for a more consistent response across notes and phrases, helping the effect feel tighter and more controlled.
• Wah: Activates a wah-style tonal movement together with the swell effect, adding extra expression and a more vocal character to the sound.
