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.

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.

The paraphonic Poly Synthesizer section has been beefed up with an additional octave, optional oscillator drift, velocity control, new modulation capabilities (including pulse-width modulation), and additional waveforms. The Lead Synthesizer section has been enhanced with a more powerful arpeggiator, additional waveforms, adjustable note priority, and numerous other small improvements. We’ve turned the Quadra’s rudimentary LFO into a full-featured, multi-waveform, tempo-syncable LFO. We’ve added a deeply flexible bender section that allows pitch bend wheel data to independently bend pitches and modulate filter cutoff for each instrument section.

Highly Effective
We modeled the ARP Quadra’s 14-stage phaser, and added additional effects – chorus/flanger, echo, and reverb – that can also be turned on and off independently for each instrument section. Imagine strings bathed in reverb, a poly synth slowly phasing and flanging, and a lead synth with a slapback delay, all layered together to create a beautiful swirling pad. The sound design possibilities are endless!

Four Sides Live
Quadra includes a multiple out version for maximum flexibility. The standard “Quadra” instance mixes the four sections to a summed output. “Quadra Multi Out” includes five sets of outputs: a standard stereo mix, plus dry independent outputs for each section, as found on the original hardware.
