Fold is a distortion synthesis audio effect plug-in that only the engineers at Delta Sound Labs could dream up. Calling on their background in modular hardware design, the team has found a novel approach to creating warmth and distortion in software. By using an assortment of modules in an in-series FX chain, Fold imbues input signals with harmonically rich overtones and, if pushed to the extremes, completely transforms them with a unique form of distortion.
At the heart of Fold is its wavefolding engine. First pioneered by synth legend Don Buchla, wavefolding is the act of folding a wave back on itself after reaching a given threshold. While this naturally produces distortion and harmonics, Fold also ships with a bit crusher module to further smash the input signal. Fold's combination of oversampling, distortion, and wavefolding results in tones that are timbrally rich on one hand, and over-the-top destroyed on the other, even with simple periodic input signals.
To tame the sound, Fold comes with an analog emulation of a resonant low-pass filter that offers more control over any unhinged results. Each parameter is also syncable to its own LFO, each of which has an amount slider and may be synced to a host tempo within a DAW for more creative sound design and mixing effects. Fold also ships with a number of professionally designed presets that showcase the versatility of its engine.

The Modules and Effects
HP Filter. This is a TPT styled high-pass filter with resonance control underneath the frequency knob. It's great for creating filter sweeps on the front end using automation lanes in a DAW.
Drive. Drive is an amplitude dependent distortion module. You can crossfade between soft and hard clip distortion using the horizontal slider underneath the drive knob.
Wavefolding. Wavefolding is a type of distortion synthesis that occurs when the amplitude of an audio input exceeds a defined threshold. The peaks that exceed the defined threshold are inverted into a series of amplitude folds producing rich timbres and textures. This kind of distortion synthesis really shines when used on simple sounds like sinusoids or standing waves, even single guitar notes. Use the oversampling menu in the toolbar view to choose x1, 2, 4, 8, 16 oversampling. Higher oversampling values incur a greater CPU overhead but mitigate any unwanted aliasing caused by the Fold module.
Crush. Crush allows you to quantize your incoming signal to emulate a classic bit crushing effect. Both depth and rate are tied to one single knob and scaled in such a way to leverage this kind of distortion synthesis as best as possible. Listen to the difference when you change the Oversampling factor!
LP Filter. This low-pass filter is an analog emulation of a resonant low-pass filter. There is a resonance control slider underneath the filter frequency cutoff knob in a similar fashion to the high-pass filter on the front end of the signal chain. This filter helps tame and sculpt any unwieldy distorted textures.
LFO. Each module has its own dedicated Low Frequency Oscillator (LFO). Each LFO can be turned on by clicking the small button located in the top-left corner and has its own dedicated amount slider located next to the LFO Speed slider. You can choose from sine, square and saw waveform types. By clicking the quarter note button, Sync mode is activated and locks the phase to the tick reported by the DAW or host.
FX/Envelope Follower. This is a Dry/Wet control that regulates the proportion of processed to unprocessed sound. Adjustments to the FX knob do not affect signal processing, as this is done exclusively by the other modules. The envelope-shaped button underneath the knob will override the FX knob and the amount of effect applied will be relative to the peak amplitude of the incoming audio input.
Toolbar View. Use the preset combo box to select any of our factory presets or make and recall your own presets. You can use the nudge buttons (left and right) to quickly audition presets. The Oversampling drop down menu contains options for x1, x2, x4, x8, and x16 oversampling factors.
Creative Strategies with Fold. Fold yields extremely interesting results with low frequencies—try folding your kick drum, any bass register instruments, or simply a sine wave from your synth! Fold can also be used to add high-frequency energy to a synth lead line. This works well in combination with Fold's FX Amount parameter, allowing you to dial in the exact amount of energy you want. Distortion has long been essential to guitar players—Fold's unique combination of distortion and wavefolding on electric guitars is worth a lengthly exploration. Try with chords or even bass lines on lower registers.
