At first blush, the Anti-Oscillator appears as a standard voltage controlled oscillator, with volt per octave input, linear and exponential FM inputs (with attenuators), fine and coarse frequency controls, and dedicated triangle output. But then, there is the “MAYHEM” output!
Mayhem starts as a square wave and morphs into twisted, animated waveforms as the “Init Wave” control travels clockwise or is modulated. Not a standard waveshaper or wavefolder, Mayhem produces multiple, altogether new waveshapes in series as it is modulated. Sometimes creating an almost PWM “fat” sound, and other times creating very organic, metallic sounds as the Anti-Oscillator is modulated. The timbres generated by the Mayhem output are often eccentric and very rich in harmonics, perfect for a filter to “bite” into.
The waveshaper CV attenuator (Wave Env) is normalled to feed the triangle output in when no input is connected. The exponential and linear CV inputs are normalled to feed the Mayhem output into their respective CV input when no CV input is connected. When using the triangle output and with no CV input connected to the exponential input, for example, you can turn the the Exp control clockwise to progress through new wave shapes, starting with a triangle instead of a square for a smoother waveshaped output.
The Anti-Oscillator is know for its great FM response and capability to achieve fat and clangorous sounds. It pairs perfectly with the Wiard Oscillator for modulation, and the Borg and Boogie filters to shape and tame the Mayhem output!

You’re in for years of exploration.
The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks. But there are significant updated schematics to have the most out of your modular setup.
Erica Synths DIY Modulator is 35mm deep, skiff friendly, has solid mechanical construction and doesn’t require wiring.
The Modulator essentially is LFO with simultaneous triangle and square wave outputs, clockable S&H with external CV input and noise source. A kit comes with two versions of noise generator – simple, transistor-based and more complex Zener diode-based one. Latest provides perfect, full spectrum white noise.
