Strengths
- A genuinely affordable mini-key entry into DX7-family FM synthesis, at a fraction of the flagship DX7's price
- Compatible with real DX7 patches and programming concepts, giving access to the same iconic FM sound family
- Battery-powered mini-key portability made it a genuine budget grab-and-go FM synth
Trade-offs
- Mini-keys and a smaller, simpler interface than the DX7 make patch editing even more cramped
- Same real FM-programming learning curve as the DX7, without the flagship's fuller-size keybed
