Dove Audio were showing their WTF Oscillator in MU (Moog Unit) large format modular - also available as Eurorack.
The WTF oscillator is a new idea that allows you to transform two waves, a front and a back wave, by opening a window from the front to the back, creating a new waveform based on the window size and shape.
Both formats should be available by mid November:
Eurorack version £325
MU Version £425
