This Ableton tutorial covers four oscillator effect parameters inside Wavetable's Classic and Modern modes. Classic mode offers Pulse Width and Sync: Pulse Width adjusts the width of a waveform and works across all wavetables, accepting both negative and positive values. Sync introduces a hidden oscillator that resets the phase of Wavetable's oscillators, reshaping the timbre in the process.
Modern mode's two parameters follow similar logic but with a different character. Warp produces an effect comparable to Pulse Width, while Fold applies wavefolding distortion to the oscillator signal. Together, these four controls give you a range of waveshaping options within a single device, from subtle width adjustments to more aggressive timbral distortion.
