The Cherry Audio Quadra is a meticulously crafted virtual instrument that faithfully recreates the rare and iconic ARP Quadra synthesizer from 1978. This digital version brings the classic analog character into the modern era, delivering an authentic experience of a synthesizer long regarded as a unique and highly sought-after instrument. The Quadra emulation captures the essence of the original while introducing enhancements that expand its sonic capabilities beyond what was previously possible.

Each of the four instrument sections in the Quadra can now be assigned independently across the keyboard with extended transposition ranges, allowing for complex layering and performance options. The polyphonic synthesizer section features additional octaves, oscillator drift for analog warmth, enhanced modulation options including pulse-width modulation, and velocity sensitivity. The lead section benefits from a more powerful arpeggiator and new waveforms, while the LFO has been upgraded to a full-featured, tempo-syncable unit with multiple wave shapes. A flexible pitch bend system independently controls pitch and filter modulation, adding expressive depth to the sound.

The Quadra also includes an accurately modeled 14-stage phaser alongside chorus, flanger, echo, and reverb effects that can be applied separately to each section, enabling rich and immersive soundscapes. Multiple output modes provide workflow flexibility, including separate dry outputs for each section to facilitate custom mixing and processing. With over 450 presets crafted by experienced sound designers, the Quadra offers a vast palette of inspiring sounds for any production style. Compatible with major plugin formats, it delivers high performance with low CPU usage, making it a powerful addition to modern studios.
