Vintage Synthesis, To The Fourth Power

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. 

Quadra-matic

Cherry Audio's Quadra introduces improvements throughout every section, bringing out the full potential of the original ARP design. Each instrument section can now be layered anywhere across the keyboard, and we've increased transposition ranges for most sections. 

Quadra includes over 450 presets from a diverse, all-star team of sound designers:

Led by veteran sound designer James Terris, we enlisted the help of Julie Kathryn, Huston Singletary, Katharine Fountain, Dave Polich, and Brendan Dreaper to create over 450 stunning Quadra presets. Each sound designer brings their own style and character to the process, and the results are awe-inspiring.
