A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

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?

Remember when you used to go to the dentist and the receptionist had a sliding hatch that would open and say "Mrs Smith to see the Dr in room 3 please"? Well this is much the same, the "front" wave is represented by the panes of glass on that window, the rear wave is the cheery receptionist.

As you slide open the window in the front wave the rear wave can be seen in that window. You can open and close this window with CV control.

Here's an example waveform;

Example WTF output wave in Yellow, with a red square wave for the front waveform and a blue sawtooth for the rear

This creates a totally new waveform that could, for example, start with a sawtooth, then change to a square wave part way through, then go back to a sawtooth for the remainder of the waveform cycle.

All this can be done with full CV control, allowing you to route your existing LFOs, EGs and sequencers to any or all of the parameters.

Features



32 Waveforms + Noise

There are 32 waveforms plus noise in the module and you can morph between any two. There are of course the usual suspects - sawtooth, sine wave, triangle wave and square wave. The remaining 28 waveforms are all newly created to mimic certain types of sounds, like vocal formants, distorted waves, metallic sounds and many more.

You can select the front and rear waveforms with independent control voltages enabling you to create incredibly rich sonic textures.

Wave morphing (Wavetables)

Now with linear interpolation (also know as wavetables or wave morphing) for both front and rear waveforms to give super smooth transitions from one wave to the next, this sounds incredible when using CV modulation for the waveforms in combination with the window transform function.

Tuneable Noise

The noise is tuneable, when you enable noise for the rear wave you can adjust the frequency the noise is generated at, allowing you to go from a white noise to a retro 8 bit game console style noise.

Advanced 'PWM'

You can also set the rear window to be a DC level giving you the ability to create PWM like sounds with any of the 32 waveforms.

Wave Inversion

You can also invert the rear waveform which adds a whole new level of sonic capability to the WTF oscillator.

Dual Window Mode

We've also added a 'dual' mode to the window function, so you can change between a single window opening and closing or a dual window.

CV Control of Waveforms

Finally, we've added the ability to change both the front and rear waveforms using control voltages, used in conjunction with a sequencer this gives you an incredibly powerful sound source full of previously unheard of sonic power.

Audio Demos

When you combine all the features you end up with amazing sounds like these;

First a sequencer that starts with a saw tooth, then we mix it with a more complex waveform, then we start adding CV control of window width and then control of front and rear waveforms (digital delay and low pass filter added by external modules)

Below we have another sequence showing the ability to pitch the noise, remember when in 'noise' mode the rear waveform CV becomes the noise pitch CV.

Stretch Goal 150%

When we hit 150% we'll shrink the panel size for the Eurorack version from 20HP to 16HP, we'll also be moving the sockets to the bottom. It's a lot of work as it means a complete PCB redesign, front panel redesign and further PCBs/Panels need to be ordered and built to confirm alignment.

It would look something like this;

16HP version of the module

Module Requirements



For the euro-rack version the WTF module requires 20HP of space and needs 30mA from the +12V rail, 30mA from the -12V rail and 100mA from the 5V rail. The module must be supplied with a regulated 5V supply rail in addition to the +12 and -12 rails.

Things left to do

There are a few minor things left to do, these are simple things that we've simply run out of time to do.
