Critic Reviews

Pocket Operator Modular 400 - Teenage Engineering - Waveform Magazine

waveformmagazine.com

Teenage Engineering's Pocket Operator Modular 400 is a visually striking tabletop synth that offers a unique, albeit quirky, experience. While its design and playability are commendable, the frustratingly imprecise knobs and sequencer can hinder sound sculpting. The DIY assembly is easy for those with basic skills, but the modular aspect feels limited. Its onboard speaker is a nice touch, even if it's not particularly loud. Overall, the POM-400 is fun and engaging, especially for beginners, but seasoned synthesists may find its shortcomings a deal breaker.

Teenage Engineering PO Modular 400 review | MusicRadar

musicradar.com

Teenage Engineering's Pocket Operator Modular 400 presents a curious blend of fun and frustration. While it boasts an impressive array of modules and a striking design, the lengthy assembly process and imprecise controls can be off-putting. Users may find the tuning and control options less than reliable, leading to a less musical experience than expected. The quirky build, although engaging, doesn't always inspire confidence during use. This synth is more of a beginner's semi-modular than a true modular experience, which might leave seasoned players wanting more. In essence, it’s a captivating concept hampered by execution issues.
