Quadra

Cherry Audio Quadra brings the character of the 1978 ARP Quadra into a flexible virtual synthesizer. Its four sections—bass, strings, poly synth and lead—can be split across the keyboard or layered for full, textured sounds. Build punchy monophonic bass lines, lush 70s string ensembles, warm chords and expressive dual-oscillator leads, with a Drift control adding analog-style movement to the poly section. A modeled phaser, stereo chorus/flanger, tempo-syncable echo and reverb provide individually routable sound shaping. More than 400 presets offer starting points for retro electronic tracks, synth-pop and cinematic arrangements. Tempo-synced arpeggiation, aftertouch support and full DAW automation help bring performances to life, while the multi-output version lets you process each section separately. Quadra suits producers and keyboard players who want vintage synth textures with modern layering and workflow options.
