Sinevibes has introduced Turbo S - a 'dynamic waveshape transformer'.
Here's how Sinevibes describes it:
It features the same 6 unique waveshape models developed for it's smaller brother, Turbo, all of which offer mind-bending transformations. But now these models can be modulated by a step sequencer, opening a new dimension for complex pulsating and morphing sounds. This sophisticated device offers up to 16 steps, 12 different speed settings, infinitely variable swing, as well as adjustable time and smoothness - allowing you to create a myriad of different patterns.
All of this is wrapped into a really innovative user interface, which you will learn in no time and endlessly enjoy it's visual lightness and intuitive operation.
Six high-definition waveshape transformation algorithms
Step sequencer with up to 16 steps, multiple timing and shape options
Intuitive, resolution-independent user interface with graphical feedback
64-bit universal compatibility
Turbo S requires Mac OS 10.5 or later. It is a Universal Binary for both Intel and PPC, 32/64 bit. You will also need an AudioUnit host application that supports Cocoa user interface technology. Sinevibes recommends installing the demo version to test compatibility.
