The Cherry Audio Quadra is a super-accurate and immensely improved emulation of the ARP Quadra synthesizer originally released in 1978 - a rare and coveted “unicorn” instrument in the synthesizer world reproduced for the first time as a virtual instrument. We've addressed the original Quadra's shortcomings and wildly expanded it for an experience that blows away the real thing in every conceivable way. 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 we make a killer emulation of the aforementioned onboard phaser effect we added a stereo chorus/flanger a syncable echo and studio-quality reverb - all individually routable for unprecedented effects flexibility.
