Strengths
- Extends the Prophecy's physical-modeling engine to real polyphony, letting you play chords with the same modeling technology
- Deep oscillator algorithms (including cross-modulation and ring mod between virtual 'strings' and 'reeds') give a genuinely wide sonic palette
- A cult favorite among sound-design-focused players specifically because so few synths ever attempted true modeling polyphony
Trade-offs
- Extremely deep programming model means most surviving units are still running factory patches rather than fully custom sounds
- One of the rarer Korg synths of its era, making both units and repair parts genuinely hard to source
