In his latest video, synthesist John L Rice explores the sonic possibilities of the Dove Audio WTF oscillator.

The Window Transform Function (WTF) oscillator lets you ‘wipe transition’ between two different wave forms, a bit like PWM on steroids.

The idea is that you have two waveforms, one ‘in front’ of the other, and WTF lets you ‘slide a window’ to transition from one waveform to another in a new way, and also to create new types of waveforms.

See the Dove Audio site for details..
