Cherry Audio's Pro Soloist resurrects the 1972 ARP preset synthesizer as a fully programmable virtual instrument, radically expanding its sonic vocabulary while preserving the expressive touch-sensor immediacy that defined the original hardware. The emulation captures the character of ARP's vintage analog circuitry, particularly the interaction between the resonant filter and voltage-controlled oscillators, which produces those characteristic warm, slightly nasal lead textures that defined early 70s prog rock.
What distinguishes this plugin from a straightforward emulation is its modernization for contemporary production. The addition of polyphonic voicing, layering, and splitting transforms a monophonic preset device into a flexible synthesis workstation. The integrated mod matrix enables complex modulation routing beyond the original's limited architecture, while the included studio-quality effects address the limitations of standalone hardware from that era. The 30 classic presets provide historical reference points and sonic inspiration, though the programmable controls invite deep exploration of the Pro Soloist's DSP model.
The plugin's touch-sensor aftertouch parameters - originally controlling vibrato, pitch bend, and filter modulation - translate naturally to modern MIDI controllers, making expressive real-time performance accessible. The sonic character skews toward aggressive, cutting tones rather than ambient textures, making it particularly effective for lead synthesis, stabbing strings, and brass emulation where definition matters in mixed contexts.
The Pro Soloist appeals to producers seeking vintage character with modern flexibility, particularly those valuing hands-on sound design over preset-dependent workflows. It occupies a specific niche between period-accurate emulation and contemporary synthesis tools.
