According to Cherry Audio, the new soft synth is the first reproduction of the original “unicorn instrument”, the ARP Quadra. The developer adds that it has “addressed the original Quadra’s shortcomings and wildly expanded it for an experience that blows away the real thing in every conceivable way.”
Such improvements include a streamlined patch browsing system, a “richer and fatter” tone, and an expanded effects section that boasts stereo chorus/flanger, echo, and reverb.
Quadra is centred around four synth engines: Bass, String, Poly and Lead. Each section is titled appropriately, with Bass being home to a gritty monophonic synth part; String reproducing the classic string ensemble sound of the original Quadra; the Poly section including saw, pulse, Spike and Hollow waveforms for synth chords and pads; and Lead being a dual-oscillator synth with a pleasing amount of modulation possibilities.
In our review, we say of the synth: “As you’d hope, the developer has expanded on some areas where the original synth had weaknesses, such as its patch storage system. Cherry has also added extra effects and various other performance enhancements.
