Curve 2

Unique Creative Synth for Inspired Production & Deep Experimentation


Curve is a software synthesizer that gives you completely new possibilities for experimentation and detailed tweaking, with an irresistible waveform editor, huge sound library and slick interface.

Curve's oscillators, LFOs and envelopes are all powered by custom waveforms that you draw yourself using Cableguys' unique Wave Editor. Take control like never before to design everything from deep, firm basses and aggressive FM snarls to inspirational rhythmic loops and endlessly shifting soundscapes.

A pair of 18-mode filters bring shape, flavour and texture to any sound. Add depth and dimension with up-to-16-voice unison. Create precisely targeted modulations with the modulation matrix — or twist the Macro knobs for immediate satisfaction.

For instant inspiration, dive into a huge — and constantly growing — sound library filled with quality presets by renowned sound designers such as Michael Kastrup, Pluginguru, Myagi, Xenos Soundworks, Soundsdivine, and hidden pearls from the ever-creative Curve community.

Try it now — download the demo and get creative with Curve 2.

Sonically, it's a spectacular synth: expansive, rich, full of life and movement, and always interesting. The oscillators are supremely versatile, generating anything from novel twists on the conventional analogue waveforms to crazy 'digital' tones.

Design Waveforms

Any waveform you can imagine is just a click away with Cableguys' famous wave-editing tools. Draw custom oscillator shapes and design unique rhythmic LFOs and envelopes.

Stack Oscillators

Layer up to three aliasing-free oscillators, all with noise and FM.
Mix two waveforms inside every oscillator — modulate the blend for expressive sonic motion.

Tweak Filters

Pump your oscillators through powerful dual filters with flexible routing possibilities. The diverse filter types include our acclaimed Sallen-Key analogue-modelled design with adjustable drive.

Add Movement

Modulate anything with anything in the modulation matrix. Hook up envelopes, LFOs and more to bring life and motion to your patches. The one-page matrix view always shows you precisely what's happening.

Find That Sound

Explore an ever-expanding world of sound with Curve's powerful Library Browser. Easily filter by sound type, rating, name, and more. Sync to get new presets every month and stay inspired.

Take Creative Control

We don't all want to be scientists of sound — not all of the time, anyway. Macros let you forget about the technical stuff by controlling complex parameter sets for you behind the scenes. Four simple controls with endless creative outcomes.

I made [the lead sound for Ruby] with Cableguys' Curve synth. It sounds like this really dirty guitar sound. This is how I got into the groove of the track — basically the whole inspiration.


Curve is my new favourite software synth. I love how easily and precisely I can edit the oscillator waves and shapes. It is incredibly flexible and very user-friendly. To top it off, it has a massive sound library.


Loving the new plugs by Cableguys — so intuitive and creative! Curve 2 can make some nasty basses.


Curve 2 is a really amazing synth — so flexible and powerful.
