Quadra Synthesizer Plug-In Download

The Cherry Audio Quadra plug-in is a super-accurate and immensely improved emulation of the ARP Quadra synthesizer, originally released in 1978. This rare and coveted “unicorn” synthesizer is reproduced for the first time as a virtual instrument. Quadra introduces improvements throughout every section, bringing out the full potential of the original ARP design and each instrument section can now be layered anywhere across the keyboard, with increased transposition ranges for most sections. The paraphonic Poly Synthesizer section has been beefed up with an additional octave, optional oscillator drift, velocity control, enhanced 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. Quadra's rudimentary LFO has been turned into a full-featured, multi-waveform, tempo-syncable LFO and a deeply flexible bender section has been added that allows pitch bend wheel data to independently bend pitches and modulate filter cutoff for each instrument section. Cherry Audio 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.
