What it actually does

Fold EQ spectrum with folded bands and a hand-drawn curve

Radical Band Control

Fold bands left and right, over each other, to enjoy a plethora of multi-band sound design miracles only possible now!

Band type list, fold mode list and the serial chain editor

Endless Options

Choose between 4 different ‘Fold’ modes on 11 different band types including Ripple, Brownian, and Runaway Resonator. Each Fold mode has a different left–right function: Time is prelay–delay, freq shift is negative–positive, FFT is phase lock–spectral gate, and Transient is cut–boost. Also included is a serial signal flow node dragger when in serial mode.

Macro knobs, LFO and envelope follower tabs

Maximum Modulation

Nearly everything can be modulated with 5 customizable LFOs, 4 mappable macros, and 3 envelope followers to make your sounds flow into uncharted territory. Go even further with our Mod Matrix section that allows any combination of modulators as well as Aux Mods.

Audio Demos

The same take twice. Nothing else in the chain, no other processing, no level matching. Press play on one and the other stops.

The details

Fold EQ

A plugin is a piece of software that runs inside a music production application, the sort of thing people mean when they say DAW. Ableton Live, FL Studio, Cubase, Reaper, Logic Pro. It sits in the signal path and changes the sound on its way through. Fold EQ installs as VST3 on Windows and macOS, and as an Audio Unit on macOS, so Logic Pro and GarageBand work too as of version 1.1. The one exception is Pro Tools, which loads only AAX. Fold EQ runs unlocked in demo mode for as long as you like, so you can hear it on your own material first.
