What is a WTF Oscillator?
WTF stands for Window Transform Function and this oscillator gives the owner a new and unique way to morph between waveforms. It’s designed to fit in your modular synthesiser, either in Euro-rack format or MU format.
How Does it Work?
The concept is that you have two waveforms, one in front of the other. You are then able to open a window, or gap, in the wave at the front to show a portion of the wave behind. This let’s you create totally unique waveforms previously unobtainable.
Here’s an example waveform with the output wave in Yellow, with a red square wave for the front waveform and a blue sawtooth for the rear;
You can of course modulate the window width with CV, in addition you can change the front and rear waveforms with a CV.
We’ve also added a ‘dual’ window mode so you can have two windows, as well as an ‘invert’ option for the rear waveform giving in more sonic potential. Here’s a short video with explanation and example of a CV modulating the window width;
We’ve also included a noise option for the rear waveform, the noise is also tuneable going from those nintendo-esque chip tune style noises up to white noise.
How does it Sound?
Here are some demonstrations of the WTF module in action;
The module will be available in both Euro-rack and MU format (supporting both MOTM and dotcom power format). The Module requires 30mA from the +12V supply, 30mA from the -12V supply and 100mA from the 5V supply.
We did a couple of audio rate modulation demonstrations, with a dotcom VCO modulating a waveform and also window width
Where can I get one?
Our kickstarter campaign finished with funding reaching 128%, We’re now processing supplier orders and getting everything set up for our first production run which we expect to ship in October 2018.
After this we will be selling through a few dealers and distributers, once all the paperwork is sorted we’ll be providing links to dealers around the globe.
