Cherry Audio releases ARP Quadra synthesizer emulation

mardi 23 novembre 2021, 20:51 , par MacOSX Audio
PRESS RELEASE — Oakhurst, California — Cherry Audio is capping off an incredible year of new products with the release of Quadra, their highly anticipated reimagining of one of the quirkiest, rarest, and most curiosity-inspiring vintage synthesizers of all time, the 1978 ARP Quadra.
Four On The Floor
During the late 1970s, ARP set out to create a new instrument that combined the best features of several of its existing synthesizers into a single do-everything keyboard. The Quadra merged a mono bass synthesizer, string synthesizer, paraphonic poly synthesizer, and a powerful duophonic lead synthesizer into a single instrument, with the various sections layered across an aftertouch-equipped five octave keyboard. While the individual synthesizer sections lacked some of the control associated with dedicated instruments, there were several surprisingly great features added, including a rudimentary arpeggiator, unique “trill” feature, dual portamento, rudimentary patch memory, and a fantastic 14-stage phaser. The layering of these sounds led to some wonderful possibilities, and many artists made great use of the Quadra, including Tony Banks of Genesis, John Carpenter, and Pink Floyd.
However, the ARP Quadra was not without issues. In the late 1970s, ARP was hurting financially, and there was a lot of pressure to build an instrument that could compete with the new Sequential Circuits Prophet-5. As a result, history records that the Quadra was rushed into production too early, and it’s full of odd design choices. It’s quite fragile and failure-prone. The five-octave keyboard protruded unprotected from the front of the chassis, leaving keys vulnerable to damage. The built-in patch storage only stores the state of a few dozen buttons (and none of the sliders), rendering patch storage nearly useless. All in all, it was poor competition for the innovative Prophet-5, and didn’t sell well as a result. For a long time, the Quadra was largely forgotten.
But oh, the sound… it sounded wonderful. Rich, deep, warm, smooth, and analog in all the right ways!

Behind The Lines
Over the decades, the ARP Quadra has inspired endless curiosity. While discussing vintage synthesizers last year at Cherry Audio, they realized that none of them had ever been in the same room with a working ARP Quadra, and they’d long been curious about this unicorn synthesizer. And if they were curious about it, others likely were as well! They set out to find the unfindable: A completely operational Quadra. $7,200 later, they had a fully working unit in the studio.
Fantastic Voyage
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 they’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. They’ve turned the Quadra’s rudimentary LFO into a full-featured, multi-waveform, tempo-syncable LFO. They’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.

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!
Finally, a team of six sound designers was assembled to create a wealth of presets for this instrument. Led by Cherry Audio’s lead sound designer James Terris, they enlisted the help of Katharine Fountain, Huston Singletary, Julie Kathryn, Dave Polich, and Brendan Dreaper, resulting in well over 400 stunning Quadra presets. Each sound designer brings their own style and character to the process, and the results are awe-inspiring.
Four Sides Live
Cherry Audio’s Quadra comes in two flavors. “Quadra” is the stereo version, and works like most other virtual synthesizers. “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.
Dina Pearlman, daughter of ARP founder Alan R. Pearlman, and Executive Director of the Alan R. Pearlman Foundation:
Cherry Audio continues to design quality ARP-inspired virtual instruments. Their latest offering captures the lush, exquisite essence and layout of the rare ARP Quadra. Emulating this unique hybrid instrument offers an experience to explore and create that will be welcomed by the synth community. We are grateful that companies continue to build on the pioneering engineering that Alan R. Pearlman inspired through his instrument designs.
Cherry Audio’s new Quadra Synthesizer is available now for the insanely low price of $39. It’s available in AU, VST, VST3, AAX, and standalone formats, and requires macOS 10.9 or later (including Monterey) on Intel or Apple Silicon. Quadra is also included with Cherry Audio’s new Synth Stack 2, a collection of ten virtual instruments normally priced at $249, but discounted to $199 during Cherry Audio’s 2021 Holiday Bonanza.
