Ranked by what users actually praise

Overall Impression

Tracking is the SY-300's standout feature, praised as fast and accurate where hex-pickup synths struggle. Multiple commenters directly compare it to Roland's GR-33/GR-55 and report the SY-300 tracks polyphonically without the pops, boings, and mistracked notes those units produce, largely because it processes the analog signal rather than converting it to digital/MIDI. Users highlight that it works with a plain 1/4in guitar or bass cable, no special pickup needed, and that latency is essentially nonexistent since there's no pitch-to-digital conversion happening.

Opinions on the factory presets are deeply split between 'cheesy 80s toy' and 'ambient goldmine.' Several commenters dismiss the stock patches as robotic, shrill, or like 'Super Mario Bros' and 'elevator jazz,' with some saying only 5-6 of dozens are genuinely usable. Others found real emotional and ambient value once they dug into reprogramming with the Blender randomizer or Tone Studio software, describing shimmery pads, soundscapes, and Fripp/Vangelis-style textures achievable with patience and effects like reverb, delay, and volume pedals.

The $700 price tag draws frequent pushback relative to perceived value. Commenters repeatedly question whether the sound quality justifies the cost, with some saying similar tones are cheaper on a keyboard or comparing it unfavorably to cheaper Boss/Korg multi-effects units from decades past. Others counter that for $450-700 the versatility, patch-saving, and live-performance convenience beat assembling several boutique pedals, calling it a worthwhile investment for gigging musicians who want one flexible box.
