Recently I had the pleasure of meeting Dan Wahlbeck, founder of DPW Design. Dan designed the MÖG AV-1 Attenuverter eurorack module which was released last December. Dan’s previous product was the D1 4-Band Distortion Pedal.

At Cymru Beats 2017, in June, Dan Wahlbeck was showing off his latest creation the MÖG WF-1 Wavefolder eurorack module. That day was a particularly hot day but not as hot as the Wavefolder WF-1, the reason being the WF-1 was literally Hot Off The Press! Dan had just finished building the first batch of 100 units the night before travelling from Sweden to the UK for the Cymru Beats Synthesizer Meet.

Talking with Dan, one quickly realises that he is not only a cool guy, he is also very passionate about his work.

I admit I have a weakness for eurorack modules featuring a great-looking front panel design and interface. Of course, taste is a subjective matter and based on my subjective sense of taste I like the look of this 12HP MÖG WF-1 Wavefolder. By the way, those undulated lines spaghetting across the front panel are not meaningless, they reflect signal paths.

With this wave folder, you can manipulate the incoming signal in several useful ways including independent folding of the top and bottom (positive, negative) of the input signal, independently adding or subtracting a square wave from the positive and negative part of the signal, symmetrical modulation, cv control over offsets, mono and stereo out, logical signals based on folding parameters, limiting, distortion and more.

The image to the right shows adding/subtracting a square wave from a sine wave input signal

With the Wavefolder Expander E-1 you gain CV control, on/off, of the Limiter and Distortion functions. You can turn functions on and off at a frequency of up to 1.5Khz.
