Squall Reverb

Squall is a port of Mutable Instruments Clouds reverb for the Korg NTS-1 mkII.

Ported by Daniel Majid Mirzakhani.

Original Clouds DSP copyright Émilie Gillet.

Highlights

• Uses DSP from the original Clouds synth module for an accurate emulation of the onboard reverb.
• Playable DPTH range from short ambience to long dreamy washes.
• Knob B DPTH also controls wet amount to closely emulate the 'one knob' functionality of the original module.
• FREEZE holds the reverb tail and limits fresh input.
• SCAN from 50% to 100% colors the frozen buffer. From 50% to 0% increases buffer leak to allow in new audio.

Controls

• Knob A TONE: Gentle low-pass control on reverb tail.
• Knob B DPTH: Reverb amount/decay character.
• MIX Hold REVERB button + Knob B: Wet/dry mix is currently disabled.
• FREEZE Hold REVERB button + Knob B: Freezes the reverb buffer.
  • Knob B < 50%: FREEZE off (normal operation).
  • Knob B >= 50%: FREEZE on.
  • Existing tail content is held.
• SCAN Freeze behavior shaper.
  • 50-100%: Full clamp closed (no input bleed, no leak-out) with increasing frozen color sweep.
  • 0-50%: Allows fresh-input bleed (up to 5%) while leak-out is fixed at only 0.5%.
  • 0%: Maximum input bleed and darker/less diffuse freeze color.

DPTH behavior:

• 0-50%: Room/hall style reverb.
• 50-75%: Longer cathedral-like tail with subtle modulation character.
• 75-100%: Very long dreamy tail with more obvious modulation in the decay.
