A strange name for an oscillator, but as soon as you try it out that will most probably be the first thing on your mind.

Hear the WTF1 in action here (Thank you Jonathan for allowing me to share):

The download link is further below, but here is some advice on what to expect…

The very first thing you will hear is a European ground hum and crackles….

But there is hope..


The backgound to this oscillator is a challenge from my brother ( who has been so kind to come up with designs for the oscillators I have created so far. He turned the game around and asked me to come up with an oscillator to fulfill the design, which he now created and which you can see above.


Tame the oscillator to your needs…

Expect a battered and beaten thing, which you would definitely not want to put your hands on or even plug into your new gear. It has been picked up on the streets just after I saw the dog strolling out of sight.

I managed to repair some of its issues by putting them on the parameters. So here we go for a brief ‘How to fix it’ guide.


It comes with a ground hum. More specifically it comes with three different ground hums: 50 Hz, which is commonly used in Europe and Japan for example; 60 Hz, which is the standard for the US and some other countries; 400 Hz, which can be found on airborne objects like the 747. For each of these frequencies the intensity can be adjusted in three stages. The intensity of the effect is dependent on the note you play. Of course you can cancel the mains hum to get a better signal.


The contacts are also corroded on this oscillator. So you can clean up the crackle with a parameter, which improves the response of the trigger and the stability of the tone.


Unfortunately the oscillator tents to produce a lot of varying overtones. Use the drift parameter to tame the influence of the overtones on the oscillator. Both in modulation speed and intensity. (Keep it at around 5 to get into an acidy vibe)


The basic waveform can be folded to achieve further overtones.


A simple detune.


What’s a broken oscillator without a subtle overdrive? It had to be it.


The ‘Shape’ knob is an over-all instant repair macro. It morphs between the settings above and the cleanest shape, you can achieve, so that your settings are musically playable.


Here are some ideas on what you could donate if you are thinking…

The drift parameter was tamed

A subtle detune can be achieved with the tune parameter now.
