Pioneered by Casio in the ‘80s in its CZ keyboards, phase distortion synthesis still rears its head in software plugins today. In fact, it’s inspired a new free one by nakst, known as Regency, which looks pretty accomplished.
Promising a “multi-tiered phase distortion system,” this features two generator layers, each of which has three editable multi-segment curves. These can be applied to distort the phase of each generator in series, in modulatable amounts.
