The E-MU Proteus 2000 Refill contains the original sounds from one of the most popular hardware sound modules ever to hit the music scene. Included are 1024 NN-XT Instruments and 1024 Combinators designed to function like the hardware. Each Combinator allows control over filter, resonance, attack, release, and four effects settings. Practically every major studio has used the Proteus 2000 for various music projects. The sound set covers the whole spectrum of sounds – Pop, R&B, Electronica, World, Orchestral, SFX, and more.

The Proteus 2000 was a reincarnation of the economical Proteus rack module series of the early nineties.
