Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease. Intelligent sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modeled after the inner workings of natural instruments.

Retro Future Inspired by the oil can delays of the 60s and our previous granular explorations, Curtis™ and Spunk™, Soup brings you a virtual magnetic fluid that you can record onto, slosh around, and play back from. You can use it as a unique delay effect or more like a granular synthesizer, concocting your own wholly novel sounds. Quantum Sound Soup breaks up recordings into individual sound quanta with which you can interact as if they made up an audio fluid. They can be played linearly or randomly, forward, backward, or even sideways. They can, moreover, be stirred together, giving a whole new meaning to mixing sound. Sounds Touching Not only is this an extremely visual audio experience, it’s terrifically tactile as well. With support for multi-touch, Soup lets you get in there and mangle the fluid in a way that’s simply not possible with knobs and faders. Audio Palette Soup will let you paint with sound. You can record external sounds through the microphone or import WAV files, slathering sound over the virtual fluid. Then your fingers can become play heads, reading back the sounds from any position, or multiple positions at once.
