GX-80 Synthesizer

GX-80 is a transformative virtual synthesizer that combines the unparalleled sound and features of the fabled GX-1 “Dream Machine” and its renowned descendant the CS-80, to create a powerhouse hybrid. Featuring the carefully crafted and intensely circuit-modeled DSP designs of award-winning developer Mark Barton, Cherry Audio has replicated every subtlety of the classics to create the most authentic emulation of its kind.

More than a Replicant

GX-80 is not just another CS-80 emulation. GX-80 adeptly integrates the GX-1's distinctive feature set into the CS-80 architecture; most significantly, the massive dual-layer architecture that effectively made the GX-1 the equivalent of two CS-80s and then some. The GX-1's unique highpassed resonant pulse and bandpassed sawtooth waves, octave-up triangle wave, and filter envelope inversion are incorporated, opening up a new universe of sonic experimentation. Most notably, GX-80 includes an expert reproduction of the legendary GX-1 filter, delivering exquisite timbres that even the mighty CS-80 cannot produce.

GX-80 boasts an impressive, dual-layer voicing architecture outfitted with 16 polyphonic voices per layer. The instrument is capable of sounding two different CS-80 style sounds simultaneously, while panning each rank independently, to produce exquisitely rich stereo timbres and complex, layered sounds. For ultimate flexibility and expressive performance, GX-80 provides a split keyboard mode and a clever option to simulate polyphonic aftertouch with a monophonic aftertouch controller. What’s more, the GX-80 comes pre-loaded with over 1,000 expertly designed presets and equipped with studio-grade effects, meaning jaw-dropping sounds are no more than a few clicks away. 

GX-80 is more than a best-of-both-worlds interpretation of the past, and far more than a replicant. Cherry Audio's GX-80 is an unprecedented gateway to the sounds and music of an unrealized future.

GX-80 features:

• A best-in-class virtual instrument based on two monumental analog classics: the GX-1 and CS-80
• Integrates the extended features of the GX-1 with all of the functionality of its descendant, the CS-80, for an absolutely immense sound experience; essentially, two CS-80s and more!
• Massive dual-layer voicing architecture with 16 polyphonic voices per layer: two different CS-80 style sounds simultaneously playable, in either a keyboard split or stacked layer mode, with discrete controls for layer volume and panning
• All GX-1 and CS-80 voicing parameters reproduced, including the GX-1's unique oscillator-level filtered waveforms, octave-up triangle wave, and invert filter envelope control
• Precision recreation of both the legendary CS-80 and unmatched GX-1 filters
• Four polyphonic voice ranks, each with a voltage-controller oscillator, resonant highpass and lowpass filters, noise generator, sine wave, dual envelope generators, and a velocity-sensitive VCA
• Sub oscillator LFO for each layer with sine, sawtooth, ramp, square, sample and hold, and noise intended for modulation, with tempo sync
• Recreation of the memorable CS ring modulator that modulates the summed output of each pair of ranks with its own independent oscillator
• Coarse pitch range setting for each oscillator in traditional organ footage of 16', 8', 5 1/3', 4', 2 2/3' and 2', as well as the 3 1/5' and 2 2/7' footages exclusive to the GX-1
• Virtual pitch ribbon controller precisely modeled on the actual behavior of the original
• GX-1 specific controls clearly distinguished from standard CS-80 control parameters
• Independent rank panning and independent layer stereo effects chain for expansive and breathtaking stereo tones
• Tone Selector includes each of the original CS-80 factory presets plus user sound storage
• Panel Control for selecting layers, with a utility function for exchanging settings between ranks in a layer, the Lower and Upper sound layers, or even between presets
• Over 1,000 essential presets that make the most of every unique aspect of the GX-80, crafted by a talented and diverse group of sound design veterans
• Studio-quality integrated effects: chorus/rotary, flange/phaser, digital/tape delay with sync, and reverb, including our acclaimed "Galactic" reverb algorithm, with global or dual layer modes
• Expressive touch response worthy of the originals: velocity sensitive with support for both polyphonic and monophonic aftertouch, plus a unique "last-note priority" mode for simulated polyphonic aftertouch response
• Complete MIDI control and DAW automation for all controls, with easy-to-use MIDI learn and mapping (Preset and Global)
• Cherry Audio's popular Focus zoom-in feature, as well as standard UI zoom and resize with drag
• Highly optimized coding for optimal performance with ultra-low CPU load
• NEW! Highly optimized multithreaded processing for presets using Dual and Split Layer modes
• User-adjustable oversampling control
