This is a special version of the CS33, skinned for use with the UC33 hardware controller. A matching Template for use with the UC33 is included in the packlage.
One of the aims with the CS33 design was to provide a maximum "Synth-in-a-Box" feel when used with the UC33. You can program patches from scratch never looking at the screen until it's time to apply the final touches - expression controller tweaks, FX settings etc. The identical look of template and GUI also means you don't have to do a "mental re-map" every time you switch from looking at the screen to looking at the controller.
Apart from the GUI and layout, the Evolution Edition is identical and patch-compatible to the Standard Edition. Since they share the same VSTi ID, many VSTi hosts will only allow one of the plug-ins to be present in its plug-in folder(s).
