Chaotic Monosynth



Bored of the same old synth sounds? Newfangled Audio's Pendulate is refreshingly different. Pendulate is a chaotic monosynth that uses a brand new double-pendulum-oscillator to create previously unheard sounds - biting basses, searing leads, and gritty textures. It can smoothly fade from a sine wave to total chaos, with an expanse of territory to explore in between.



Pendulate’s chaotic oscillator is based on the physics of a double pendulum. What initially looks like randomness contains underlying patterns, interconnectedness, constant feedback loops, repetition, self-similarity, fractals, and self-organization. When designing the Pendulate oscillator we took great care to bring out these underlying patterns to create something both chaotic and musical.



  • Novel chaotic oscillator based on the double pendulum makes sounds you’ve never heard before, but will want to hear again

  • Wavefolder based on the one in the Buchla 259 Complex Waveform Generator, adding MIX and CUTOFF

  • Low Pass Gate based on the Buchla 292 adds controls for POLES and RESONANCE

  • Innovative modulation UI allows modulation over every control from the main page, allowing up to 325 simultaneous modulation routings

  • MPE support allows amazing control from innovative new controllers

  • Looping Envelope and LFO each have multiple outputs generated at once, and can modulate each other, like a modular synth

  • Modulation! Every mod output to every control means up to 325 modulation points in an intuitive single pane

  • Animations! The Double Pendulum, Wavefolder, and Low Pass Gate modules each have animations to show how each module responds to your input, and to modulation

  • Fully resizable UI!

  • Intuitive Midi Learn functionality allows you to assign MIDI CCs to any control with just a click

  • Three unique color schemes to customize your look

  • 136 Presets including artist presets from Matt Lange and Matthew Wang



Pendulate is based on a new oscillator concept, which started because I was curious to know what a double pendulum would sound like if translated to audio.  A double pendulum is a simple mechanical system which is chaotic, which means what it does in the future is hard to predict from what it’s done in the past.  The initial system didn’t sound very musical, but after a lot of tweaking it sounds really great, and really interesting, and that’s what you hear today.  A great simulation of the double pendulum, and a derivation of the equations of motion can be found here.
