E-Mu Proteus X is a virtual synth for the PC with a ton of features, including a bank of 2,000 sounds. We got a good look at how Proteus X works; this video goes into nice detail on finding, loading, and saving sounds. There's also some good tutorial action on tweaking those sounds, and a bit on creating your own presets from raw samples. Since this video was shot, E-Mu has developed an upgrade called Proteus X2, which owners of Proteus X can install as an upgrade. Owners of other E-Mu desktop products have the option of getting the X2 as an add-on. For now, though, grab some popcorn and check out an in-depth look at Proteus X.
