Cherry Audio has announced the release of the highly anticipated reimagining of one of the quirkiest, rarest, and most curiosity-inspiring vintage synthesizers of all time, the 1978 ARP Quadra.

Quadra is a super-accurate and immensely improved emulation of the rare and coveted “unicorn” instrument in the synthesizer world.

Each of its four sections is independently assignable to any region of the keyboard for endless splitting and layering flexibility. The awkward patch storage has been replaced with Cherry Audio’s extensive, unlimited patch browsing system. The overall sound quality has been improved for a richer and fatter tone.

And not only did Cherry Audio make a killer emulation of the aforementioned onboard phaser effect, but they also added a stereo chorus/flanger, a syncable echo, and studio-quality reverb – all individually routable for unprecedented effects flexibility.

Quadra features

  • Over 450 presets, programmed by industry veterans.
  • All four sections superbly recreated.
  • Poly Synthesizer includes Drift control for increased analog realism.
  • Independent key range assignment for all four instrument sections.
  • Precisely replicated phase shifter with multiple mod sources.
  • Tempo-syncable LFO.
  • Multi-out instance allows separate processing of each instrument section.
  • Improved arpeggiator section w/tempo sync.
  • Accurately emulated “Touch Sensor” aftertouch section.
