Synth designer Paula Maddox (Monowave, Modal 002) has launched a Kickstarter project to fund production of the WTF Oscillator, a new type of oscillator, in Euro and 5U formats, based on ‘Window Transform Function’.
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. WTF lets you ‘slide a window’ to reveal or hide the waveform ‘in back’. This lets you transition from one waveform to another in a new way, and also to create new types of waveforms.
You can also use control voltages to modulate the size of the window opening. This can be used to create PWM-style sounds, but not limited to pulse waves.
Here’s the official intro to the WTF module:
Here’s a deeper look at the WTF oscillator:
The WTF also offers a pitched noise mode:
- 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.
- CV Control of Waveforms – You can select the front and rear waveforms with independent control voltages, enabling you to create rich sonic textures.
- 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 – you can change between a single window opening and closing or a dual window.
- CV Control of Waveforms – change both the front and rear waveforms using control voltages.
Pricing and Availability
Production of the WTF oscillator is being funded via a Kickstarter project. The module is available to backers in Euro format for £325 and in Dotcom 5U format for £425.
