Reso Delay

Inspired by RESO DELAY (HeadRush® Original)

The Reso Delay is an advanced delay with:

  • Tonal resonance
  • Quantization up musical scale (key + scale)
  • Dynamic response to the signal

Main features:

  • Delay that “plays in key”
  • Almost effect synth / harmonic
  • Ideal for ambient and sound design

It's not a normal delay → it's a creative tool

SOUND CHARACTER

  • Repetitions musically tuned
  • Resonant and “singing” sound
  • It can become atmospheric or experimental
  • Great for textures

It can turn your guitar into something “synth-like”

Control Parameters

Trigger Sens%

Activation sensitivity:

  • Low → reacts only to strong signals
  • High → reacts even to soft signals

Determines when the effect starts

Attackms

Effect input time:

  • Low → immediate
  • High → enter gradually

Useful for pad effects

Key

Reference shade:

  • Ex. C, D, E…
Stairs

Scale type:

  • Majors
  • Minor
  • Modal

Keeps the delay “in tune”

RangePicklist

Range of generated notes:

  • Low → lower
  • Mid → middle
  • High → sharper

Change the “voice” of the effect

Feedback%

Number of repetitions:

  • Low → few
  • High → many

With Reso = continuous harmonic effect

Mix%

Effect Quantity:

  • Low → thin
  • High → dominant
TailsY/N

Queue management:

  • Y → continue
  • N → immediate stop
LPFreqHz

Low-pass filter:

  • Low → dark sound
  • Higher → brighter

Check the softness

Width%

Stereo Width:

  • 0% → mono
  • 100% → super wide

Essential for ambient

Pro Tips

  • You want ambient → attack high + width high
  • Want control → lower mix
  • You want synth effect → high feedback
  • Want cleanliness → Low LPFreq

Universal setup:

  • Triggers: 50%
  • Attack: 150 ms
  • Feedback: 40%
  • Mix: 30%
  • Width: 80%
  • Scales: Minor
