E-MU releases Proteus VX as Free Download with included v2 Proteus X Composer Bank.

Proteus VX is not copy-protected or card-locked like other versions of E-MU's instrument and sampling software, and can be used either as a VSTi or in stand alone mode on Windows (Proteus VX will install and function for most users on Windows Vista but is only officially tested and supported for Windows XP).
