Critic Reviews

Roland System 500 Series Modules review | MusicRadar

musicradar.com

Roland's System-500 Series, crafted with Malekko, delivers high build quality and superb sound that nods to the original 100m modules. The standout 521 Dual VCF module offers rich, resonant tones, though some users might find the panel space limited, making patching a bit fiddly. Despite these quirks, the series captures vintage modular magic, albeit at a premium price. A worthy addition for those eager to expand their Eurorack setup with authentic Roland flair.
