Infinity 2.0 is a new "complete sound design and multimedia control studio" for Windows from Sound Quest. However, Infinity isn't just a self-contained sound creation studio, it also includes support for all major Windows audio and MIDI plug-in formats: DXi, VSTi, VST, DirectX 8.0 and MFX. This means you can use any of the included synths and effects, or indeed any that you or anyone else makes, in any compatible host, such as Cubase, Logic, SONAR, etc.
It looks incredible and the feature list is endless so the best thing to do would be to check out their extensive feature specifications here. It's due for release on 6th August and will cost $499!
