SOLD: Access Virus C Desktop. This unit is in fantastic shape for its age. We've done some restoration work, but overall, it was very clean to begin with. There are a few cosmetic issues, but otherwise this iconic 32-voice polyphonic, 16-part multitimbral synthesizer is ready to elevate your productions to the next level. Read more about this powerful synth below:

All 35 tacts are nice and snappy. They sound and feel new. Everything is very responsive :) No need to replace any of them.
Replaced 2 wobbly (but working) pots (volume and delay time). All now feel nice and smooth.
The power supply filter capacitor in this unit was a high quality Nippon Chemi-Con, but we went ahead and replaced it with a new Nichicon UHE1E101MED (100µF/25V, low-ESR) capacitor to be safe. Nichicon, a top-tier Japanese brand, is renowned for its low impedance and long lifespan, providing cleaner and more stable power to all downstream components. Its high ripple current handling and low ESR minimize heat, ensuring exceptional reliability and performance for this beautiful C Desktop.
Put a new Energizer Lithium 2032 in it, so you shouldn't need to replace the battery for the next 10-15 years.
Includes a quality power supply that runs at 12v 1.5 amps (more than enough, meaning it will run cool). This is quality power supply, and we see no need to replace it.
The power adapter inlet shaft and contact have been properly cleaned. This, in conjunction with the new Nichicon cap, means this unit does not reset when you wiggle the cord. You may still get a reset if you really go nuts (these units are known for resetting if the cord is wiggled), but you won't have any issues here.
The synth as a whole has been properly cleaned from top to bottom, inside and out. Even the knobs are all nice and clean. No gross white/funky build-up like you see on most Viruses of this era.
The black sides have been touched up with restaining. The sides on the C are tougher to restore than the B, as they have a "rubberized" coating. There are a few marks / dents on these, but nothing too bad.
This unit has the 4 original rubber feet.
The screen is nice and bright w/ good contrast. Note, the C screens don't photograph as well because they can be adjusted from red on black to black on red. We have left as red on black (the default look). We have no concerns about it. Down the road, if needed, recommend replacing with a red LUX PMVA.
This unit is running OS 6.5, which is the latest OS for a Virus C
The user RAM banks A and B have NOT been reset to factory settings. This synth seems very lightly used, but it's possible the previous owner used a software VST to control parameters. Regardless, it's possible the patches in there are quite a bit more interesting than the factory sounds, which btw, are of course still available in the ROM banks. Who knows what treasures (or tragedies) you may find :)
There are a handful of minor cosmetic imperfections. Please examine the photos carefully, as we've done our best to capture everything. That said, this synth really is in phenomenal condition for its age.

As always, we have a deep love for all things Virus, and we’ve poured our hearts into this one. It is for sure one of the nicest C Desktops available for sale on the web. Considering its excellent condition when it came in + the rest of the work done, it's well-prepared for a second life with its new owner.

Sale includes the synth and a quality power supply.

Synthesis Type: Virtual analog with subtractive synthesis, frequency modulation (FM), and phase distortion for a versatile sonic palette.
Polyphony: 32-voice polyphony for complex, layered sounds; 16-part multitimbrality for sequencing and live performance setups.
Oscillators: 3 per voice (2 main + 1 sub-oscillator):
- Waveforms: Sawtooth, variable pulse (with PWM), sine, triangle, 62 spectral waveforms.
- Oscillator sync and 5 FM modes for dynamic, evolving textures.
- Sub-oscillator: Square or triangle waveforms for enhanced low-end depth.
- Oscillator 3: Can function as an independent oscillator (via Oscillator 2 Edit) with waveform, level, and tuning control, sharing modulation capabilities.
Filters: 2 independent resonant filters per voice, up to 36dB/octave (6-pole):
- Modes: Lowpass, highpass, bandpass, band reject; serial or parallel routing.
- Overdrive/saturation between filters for gritty, aggressive textures.
- Filter envelope: Modulates filters, Oscillator 2 pitch, or FM amount for expressive sound design.
Effects: Up to 98 simultaneous DSP effects (6 per multitimbral part):
- Reverb: MIDI-syncable pre-delay, improved algorithms over Virus B.
- Delay: MIDI-syncable with variable feedback and polyrhythmic preset patterns, pre-reverb in signal path.
- Chorus/Flanger: Lush modulation effects for depth and movement.
- Retro Phaser: 6-stage stereo phaser with 24 filter poles for vintage and modern tones.
- Distortion: Light, hard, digital types, plus additional distortion types unique to Virus C.
- 32-Band Vocoder: Programmable, uses oscillators/noise as carrier, auto-sense frees polyphony.
- Ring Modulator: For metallic, bell-like tones.
- Analog Boost: Enhances bass and warmth for vintage analog character.
- 3-Band EQ: For precise tonal shaping, new in Virus C.
Modulation:
- Modulation Matrix: 6 sources, 9 destinations (e.g., mod wheel to filter cutoff, resonance, or FM amount).
- 3 LFOs per voice: 68 waveforms (triangle, saw, square, S&H, S&G, 64 digital).
- LFO 1/2: Modulate pitch, pulse width, resonance, filter gain (tremolo/distortion).
- LFO 3: Dedicated to oscillator pitch for subtle drift or vibrato effects.
- Envelope Mode: LFOs can function as one-shot envelopes for percussive effects.
- Key Follow: Adjusts LFO speed based on key position.
- 2 ADSTR Envelopes: Filter (modulates filters, pitch, or FM) and amplifier (snappy to ambient decays).
- Velocity Control: Modulates oscillator shape, PWM, FM, filter envelope, resonance, amplitude, panorama.
Memory: 1024 programs (256 user, 768 ROM, 128 multi); additional soundsets available via OS updates.
Arpeggiator: 16 independent arpeggiators (one per part) with 64 preset patterns, adjustable modes (Up, Down, Up&Down, As-Played, Random, Chord), octave range (1-4), swing, note length, and hold function; no user-programmable patterns on hardware.
Control & Interface: 32 knobs, 35 buttons, 69 LEDs, backlit LCD; Adaptive Parameter Smoothing for seamless MIDI and knob transitions; Undo/Redo and Random functions.

Additional Features:
- Unison Mode: Stacks voices for thick basses and leads, enhanced by Analog Boost (reduces polyphony to 4–8 voices).
- Twin Mode: 2 voices per note with detune/panorama spread (16-voice polyphony).
- OS 6.5: Adds enhanced effects, improved vocoder, additional modulation options (free downloadable upgrade).
- Sound Character: Warm analog emulation to sharp digital tones, ideal for trance, techno, and electronic genres (used by artists like Depeche Mode, The Crystal Method).
