Who wins on what

Ranked by what users actually praise

Overall Impression

A sound engine that still feels ahead of its time. Owners repeatedly describe the AFM+PCM combination as producing a fuzzy, crisp, lofi-yet-warm character no other synth replicates, holding its own against modern gear in a mix. Electric pianos, brass, and analog-style pads are singled out as standout patches, with several commenters calling favorite third-party patches 'modern, not 90s.' Even a pure sine wave reportedly sounds better than on newer competitors like the OpSix.

Deep, sometimes frustrating programming rewards patience. Multiple users note the menu structure is complex and repulsive at first, but that spending time with FM programming unlocks cutting-edge sounds competitive with any modern workstation. Expansion/wave cards (JSPA, Sector101, RY30) significantly extend capability, letting owners recreate Oberheim/Moog-style patches or better drum samples. Internal effects are considered dated and muddy if overdone, improving greatly when routed through outboard processors like a Quadraverb.

Built like a tank, but that means weight and repair headaches. Commenters emphasize the SY77's heavy, robust construction compared to cheaper later Yamahas, with one refurbisher describing 40 screws and three boards just to reach the keybed. Common issues include dead memory batteries, stuck buttons, broken keys, and failing floppy drives, often fixed with USB floppy emulators. Despite the hassle, the keybed itself is frequently called the best owners have used on any synth.
