# Wavetable Wave & Warp Effects *** ### Overview Current’s wavetable oscillators feature two effect slots that can further manipulate the waveform in various ways. The 40+ effects include spectral processing, formant shifting, harmonic effects, waveshaping, and more. All processing is done in the frequency domain, ensuring an exceptionally clear sound with virtually zero aliasing.
*** ### 1. Wave Effects Choose from a variety of different waveform manipulation effects. The **Wave** effects range from hard sync and other classic wave-shaping techniques to detuned flanging and bit reduction. **Pitch:** Effects that shift the harmonic spectrum up and down to create oscillator sync and harmonic series effects. * **Scan.** A unique approach to hard sync, using overlapping grains to achieve smooth oscillator sync with formant-shifting characteristics. * **Series.** Shifts up and down the harmonic series. Downward shifts stay locked to the waveform length, resulting in an intriguing formant-shifting effect. * **Sync.** Classic hard sync with depth control determining the sync rate. * **Press.** A variation on hard sync that separately syncs each half of the waveform, preserving more of its original tonal qualities. **Shape:** Phase modulation effects that can be used to create pulse width modulation and other wave-shaping effects. * **Skew.** Emulates the classic pulse width modulation found in vintage synthesizers. * **Bend.** Similar to pulse width modulation, but it forces the waveform towards the center or outer edges rather than shifting it left or right. * **Pinch.** Compresses or expands the waveform toward its center or outer edges, similar to Bend but with a fuller, more aggressive sound. * **Twist.** Generates an effect similar to FM feedback using the original waveform to modulate its own phase. **Time:** Delay-based effects that produce flanging, detuning, and similar effects: * **Reflect.** Uses four copies of the waveform delayed in different directions, creating a sound that blends hard sync with flanging. * **Flange.** Classic flanging effect where the wavetable is copied, delayed, and layered with the original waveform. * **Drift.** Combines flanging and phase rotation. Modulating this effect can produce detuned oscillator sounds. * **Dense.** Multiple copies of the wavetable are delayed and inverted, resulting in a complex effect similar to multiple parallel flangers and phase shifters. **Fold.** Zero aliasing wavefolder effects reminiscent of classic "West Coast" synths, along with unique algorithms: * **Asym.** Asymmetrical wavefolding generating both even and odd harmonics. * **Sine.** Sine wave-based wavefolding that produces a relatively clean odd harmonics. * **Hard.** Triangle wave-based wavefolding creating edgier odd harmonics. * **Wrap.** Intense hard wrap wavefolding that results in aggressive harmonics with noticeable discontinuities. **Reduce.** Zero aliasing bit crushing, sample reduction, and other decimating effects: * **Crush.** Classic bit crushing that allows you to either maximize or minimize the waveform’s individual bits. * **Bitwise.** Bitwise processing that generates complex waveforms. * **Redux.** Sample rate reduction synced to the current waveform length. * **Chop.** Zeros out a variable portion of the waveform, producing a sound similar to pulse width modulation but with a distinctly thin character. *** ### 2. Warp Effects Choose from a variety of spectral-based effects in the **Warp** section. These include spectral filtering, phase manipulation, formant shifting, harmonic effects, distortion, and more. **Filters.** Spectral filter effects based on standard filter types: * **Smooth.** Lowpass or highpass filter with a gentle slope. * **Steep.** Lowpass or highpass filter with an aggressive slope. * **BP.** Bandpass filter with adjustable bandwidth. * **Notch.** Single notch filter for precise frequency cutting. * **Comb.** Spectral version of classic comb filtering. * **Vowel.** Formant filter that simulates vocal sounds. **Spectral.** Advanced effects that harness the spectral engine for precise harmonic and phase manipulation. * **Parse.** Independently manipulates the gain even and odd harmonics to create a complex spectrum. * **Phaser.** Spectral phaser effect with exceptionally smooth notches and an even frequency response. * **Ripple.** Similar to Phaser, but preserves lower harmonics while rotating the phase of higher harmonics for a wet, dispersion-like sound. * **Data.** Creates extreme, evenly spaced notches for a clean, digital spectrum. * **Nerve.** Produces a complex phase and frequency responses with many notches and peaks. * **Shuffle.** Applies random gain and phase rotation to each harmonic, blurring the originally sound. * **Disperse.** Rotates each harmonic’s phase differently, resembling all-pass dispersion. Modulate for detuning effects. **Formant.** Effects that alter the waveform’s formants via spectral processing. Note: these effects have no impact on a saw wave due to its perfectly even spectral content. * **Shift.** Shifts formants up or down in frequency. Lower harmonics are preserved when shifting up. * **Spread.** Shifts even and odd harmonics in opposite directions, creating complex spectrums and vowel-like sounds. * **Contra.** Short for Contrast, this effect emphasizes or minimizes the difference between quiet and loud harmonics. **Harmonic.** Effects that manipulate individual harmonics in ways reminscent of additive synthesis. * **Stack.** Adds a harmonically shifted version of the spectrum to the original. Negative values replace the original spectrum with the shifted one, while positive values layer them together. * **Shift.** A unique frequency shifter that adjusts the spectrum without creating inharmonic content, unlike traditional frequency shifters. * **Stretch.** Positive values expand harmonics toward higher frequencies, while negative values compress them toward lower frequencies, which also results in a lowpass filter effect. **Distort.** Spectral distortion and compression effects with zero aliasing. * **Soft.** Positive values apply soft clipping, thickening the sound, while negative values fold the waveform, producing thinner harmonics. * **Hard.** Similar to Soft, but with hard clipping for a more aggressive tone. * **Tube.** Asymmetrical clipping that generates even harmonics, reminiscent of analog vacuum tubes. * **Maximize.** Positive values compress the waveform, and negative values expand it.
