Strengths
- 128-voice polyphony was enormous for its era, handling dense sequenced arrangements without any voice-stealing
- Expandable ROM chip sound sets let you swap in entirely different sound libraries (orchestral, vintage synth, world) on the same unit
- E-mu's analog-modeled multi-mode filters give its PCM sounds a warmer character than many purely digital romplers
Trade-offs
- Rack-only with no keyboard, requiring an external MIDI controller for any hands-on playing
- As E-mu wound down hardware production in the 2000s, official support and ROM expansion availability dried up over time
