Incredible sound-shaping capability as samples can be treated like synth waveforms and resampled through semi-modular sonic algorithms. The KDFX even offers more sound shaping possibilities with its wacky (up to 48 dB) filters, envelope followers, ring mod, delays, Lazerverb, Formant filter, etc. All with many parameters controllable in real-time or via programmable LFOs.
polyphony comparably limited to samplers in similar price range.
Arpeggiator quite sophisticated but a bit widgy to figure out.
