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!
The core of the Envelope Generator is borrowed from famous Russian synth Polivoks, but significantly updated schematics – eurorack standard positive gates, envelope amplitude, inverted envelope output, looping feature (looping on gate on). Bonus feature Gate Delay – the module outputs delayed gate signal after Attack stage. Chain up several (4-5) Envelope Generators, each with delayed gate to create evolving polyphonic synth-like pads!
Polivoks VCF is famous for its’ crazy resonance sweeps and deep, bassy sound which makes it ideal for acid basslines.
We believe, this is one of most is one of most authentic sounding famous Russian synth Polivoks VCF emulations available. The original Russian ICs K140UD12 are used in the sound circuit. We did several updates to adapt the VCF for contemporary modular synth demands. Independently buffered inputs, extended Cutoff knob range, eliminated clicks, when switching filter modes, and output stage added to eliminate signal inversion.
The Atlantis is heavily inspired by the architecture and sound of the classic Roland SH-101. It has always been one of our favorite synths and we really liked how the seemingly limited architecture allowed for all sorts of creative and musically useful sounds to be easily generated. Just like the 101, it is quick to dial in a beautifully rich bass and lead sounds but there is much more sonic territory to explore as well.
