GX-80 Synthesizer

Cherry Audio's GX-80 represents a deliberate engineering choice to bridge two distinct lineages of analog synthesis rather than simply emulate a single instrument. The plugin combines the CS-80's renowned polyphonic architecture with the GX-1's proprietary filter design and dual-layer synth engine, creating a hybrid that outperforms either source instrument in isolation. Mark Barton's circuit modeling work is particularly evident in the filter section, which exhibits the GX-1's characteristic resonance behavior and harmonic coloration that CS-80 users have historically worked around rather than celebrated.

The dual-layer configuration allows parallel or split-keyboard operation, expanding beyond typical monophonic classic synth emulations. Integration of the GX-1's octave-up triangle wave and inverted filter envelope routing restores sonic possibilities that the original CS-80 design deliberately excluded. The polyphonic aftertouch simulation via monophonic controllers addresses a genuine workflow limitation for modern players without hardware pressure-sensitive keyboards.

The GX-80 is best suited for producers seeking warm, complex pad textures and expressive lead lines with the characteristic bell-like quality that defined 1980s film composition. Engineers working with orchestral synthesis or ambient production will find the filter behavior particularly useful for creating evolving timbres. However, the instrument's sweet spot remains somewhat narrow - users seeking stripped-down, straightforward subtractive synthesis may find the dual-layer interface unnecessarily complex, and aggressive bass synthesis remains outside its intended voice.

The plugin is competently executed, though its sonic character remains distinctly retro-focused rather than forward-looking.
