I have the black E2s, sampler model. Korg was brilliant to leave some basic Virtual Analog synthesis resources in the sampler model. You can reesample internal sounds or external feeds. Samples and patterns have lots of features, so editing samples, kits and sequences s a pain on the small screen. Korg REALLY should have taken the time for a realtime software editor/librarian, like SoundDiver (10 years ago) or OverBridge (a few years after this). If I travel with a piece of gear, this is it. It does a little bit of everything, with enough creative horsepower to keep surprising myself.
