Strengths
- A genuine successor to the DR-660, combining drum sounds with basic synth bass in one affordable groovebox-style unit
- 250 onboard sounds give a wide genre range without needing to sample anything yourself
- Compact desktop format with real-time knobs makes for fast, low-friction pattern sketching
Trade-offs
- No individual outputs, limiting mixing to the onboard stereo pair
- Fairly generic late-90s PCM sound palette without a strongly distinctive sonic identity
