Synthesis made simple!
Creativity shouldn’t be complicated. Craft totally unique sounds and finish more songs with Circle². This is a versatile synthesizer plugin used for practically every genre and style of music, among sound designers, synth enthusiasts, underground producers and top pop producers alike.

Flagship synth! Over the years Circle² has achieved a cult following across the globe.
Since its release in 2009, Circle has achieved cult status, becoming a key tool in the arsenal of both seminal underground and pop hitmakers such as Hudson Mohawke, Arca, David Guetta and Deadmau5. The new Circle2 comes with even more new features, modules and effects, extending the spectrum of sounds that can be composed, and a completely redesigned user interface.
Future Audio Workshop have been working alongside Berlin-based designer Lars Hammerschmidt to bring Circle² firmly into the 21st century through the use of a contemporary design language that looks more futuristic.
The brand new VPS (vector phase shaping synthesis) oscillator is one of the most exciting new features of Circle². The new oscillator utilizes a cutting-edge synthesis technique introduced by researchers at the Aalto University School of Electrical Engineering and The National University of Ireland, and further developed for its implementation in Circle² via an academic collaboration with Future Audio Workshop.
The VPS oscillator works by glueing together a pair of sine waves with specified frequencies. Via its two parameters – which control the frequencies of the sine waves and the location at which they are glued – the VPS oscillator provides direct control of the waveform’s intricate harmonics.
Experimentation throughout the oscillator development process has led to a range of results; from dirty Reese style bass patches to ethereal pads and gritty lead lines. Modulating the parameters can produce a wide range of effects, either used subtly to give gentle movement, or used harshly to twist and contort a synth into oblivion. We’re excited to hear what synthesis results users can achieve using the new oscillator.
Circle 2 features over 100 wavetables to choose from covering a wide range of tones from aggressive sounds to softer sine wave tones.
Modulation is one of the key elements of creating sounds with Circle². Each module in Circle² that produces modulation all have large color- coded circles, which represents the output of the modulation. What makes modulation so fun in Circle² is you can simply drag the output circle of a Modulation Module and place it in any empty modulation input slot underneath the desired knob or control you wish to modulate.

“Intuitive and powerful! Within 10 minutes I’m making complex patches.”

“Circle² is amazing. I love the new Vector Phase Shaping synthesis method; It’s one of my go-to synths for generating fresh, interesting sounds.”

“I’d say that this plugin is certain to remain a favourite in my production routine. I’ve been using it for 2 weeks now and have already become addicted to its powers of sound design. Its sounds are thick and solid.”

“Beautifully designed and even better sounding, intuitive to use and remarkably CPU-efficient – easily the best virtual synthesizer value on the market, and likely in the running for best virtual synth overall.”
