Critic Reviews

Korg Delta | Vintage Synth Explorer

vintagesynth.com

The Korg Delta impresses as an analog semi-polyphonic synth/string machine, delivering high-quality retro synth strings and robust bass tones that are a joy for synth enthusiasts. Its dual-section design, with separate audio outputs and controls for Strings and Synth, offers versatility despite limited sound range compared to its peers. The intuitive joystick for modulation adds an extra layer of expressivity. However, it lacks modern conveniences like memory storage and MIDI, which may deter some users. Its solid build, designed for road use, ensures durability. Overall, the Korg Delta is a gem for those seeking vintage charm at an affordable price.
