Critic Reviews

Blast from the past: ARP Omni | MusicRadar

musicradar.com

The ARP Omni Polyphonic Analog Synthesizer is a blast from the past, offering a nostalgic glimpse into the 1970s' soundscape. While its hefty price tag and limited tweakable features might deter some, the Omni's paraphonic capabilities and rich, swirling textures made it a favorite among bands like Tangerine Dream and Kraftwerk. Despite not being truly polyphonic, its divide-down technology provided lush orchestral sounds that were indispensable for gigging musicians during its heyday. Though modern technology has surpassed its capabilities, the Omni still holds a place in the hearts of vintage synth enthusiasts.
