The W5/W7 has durable build quality, but the numpad and track select buttons often require more force as they age, making them difficult to repair.

The W5 is noted for being bulky, with only stereo outputs and sample-based synthesis, making it less flexible in sound shaping compared to more complex synthesizers.

The W-series lacks portamento/mono mode and an onboard arpeggiator, but offers a unique mixing desk that simplifies monotimbral and multitimbral operations.

The W5 lacks accompaniment rhythm/chords functionality typical of arranger keyboards, requiring manual programming via its sequencer.

Installing the OS update chips is straightforward via a panel on the bottom, enhancing the synth's capabilities with additional preset banks.

Opening the W5/W7 for repairs is challenging due to its densely packed internals; sticky track select buttons require disassembly to clean.

The W5's floppy drive is non-standard, complicating replacement, but a Gotek-style USB emulator might be available as a modern solution.

The keybed is praised for its high-quality feel, but it frequently emits aftertouch, which can affect MIDI performance.

At $200, a functioning W7 is considered a good deal, primarily due to its quality keybed, even if used solely as a controller.

The SY77 offers FM synthesis and AWM playback, providing more sound design options than the W5, which is compared to a Yamaha M1.

Despite its complexity, the SY77 is praised for its FM capabilities, offering more intricate sound possibilities for those interested in exploring sound programming.

The W5 is more suited for basic keyboard learning and playing presets, rather than deep sound programming, making it a simpler choice for beginners.
