The mercury 6 Black Friday deal takes 50% off Cherry Audio's synth plugin, so it costs $29 until Dec 1, 2026. Mercury-6 is a recreation of the Roland Jupiter-6, the analog polysynth that first shipped in 1983.
The Jupiter-6 has long been called a sleeper. It sits between the Jupiter-4 and Jupiter-8 in name only, and its dark, complex character has made it a coveted classic.
Mercury-6 is a Jupiter-6 VST built for the DAW. Cherry Audio designed Mercury-6 to preserve the qualities that made the original synth stand out, while adding features suited to a modern production workflow.
The original was a six-voice, mono-output machine. Its filter gave it a more aggressive sound than earlier Jupiters, and it made a name in techno, electro, big beat and house.
Cherry Audio extended the polyphony to 16 notes and added velocity sensitivity. It also improved the split mode and added a layer mode that stacks two sounds, with per-layer stereo panning, detuning and sustain.
The arpeggiator keeps the original's hidden Up/Down modes and gains a Random mode and MIDI tempo sync. The LFOs get retrigger options and can sync to MIDI tempo too.
Mercury-6 offers two layers, each with 16 voices, which you can play side by side as a split or layered together as a stack. Every voice has a pair of VCOs covering triangle, ramp saw, noise and square or variable pulse shapes. The filter section is multimode, with 24 dB/oct lowpass and highpass slopes alongside a 12 dB/oct bandpass option. Further tools include FM cross-modulation from VCO-2 into VCO-1, portamento and glissando, solo and polyphonic unison, single-key chord memory, independent drift for oscillators and filter cutoff on each layer, and a built-in browser holding over 500 presets.
Mercury-6 packs its effects section with distortion, a phaser you can set to 4, 8 or 12 stages, a flanger and chorus, tempo-syncable delays in three flavors, plus a choice of four reverbs. Settings can be global or per layer.
A panel control switches between layers. Its utility functions copy or swap settings between the lower and upper layers, or between presets.
Every control responds to MIDI and DAW automation, with MIDI learn and mapping at preset and global level. You also get Cherry Audio's Focus zoom, standard UI zoom and drag-to-resize.
The maker says the code is optimized for a low CPU load, with multithreaded processing for Split and Layer presets. An oversampling control is user-adjustable.
On Mac it needs macOS 10.13 or above, 64-bit, with native Apple M1 support. It comes as AU, VST, VST3 and AAX. A 3.4 GHz quad-core or M1 CPU with 8GB of RAM is recommended.
On Windows it needs Windows 7 or above, 64-bit, in VST, VST3 and AAX. A quad-core computer with 8GB of RAM is recommended.
An internet connection is required to activate the plugin. Documentation is available online from the instrument or as a PDF.

The original had six voices and mono output. Mercury-6 extends polyphony to 16 notes and adds velocity sensitivity and a layer mode. It also adds a Random arpeggiator mode, MIDI tempo sync, retriggerable LFOs and a built-in effects panel.
The effects panel has distortion, a 4/8/12 stage phaser, flanger/chorus, three delay types with sync and four reverb types. Settings can be global or per layer, so each of the two layers gets its own effects.
