Gamechanger Audio Plasma Voice

The PLASMA Voice is a monophonic Eurorack synthesizer module that produces sounds by controlling high-voltage electrical discharges between two electrodes in a custom xenon-filled gas tube. These discharges are converted to analog audio signal using a specially designed rectifier circuit. The result is a diverse range of electrifying tones that vividly capture the character and intensity of a vibrant blue electrical arc.

PLASMA VOICE engine

• Proprietary plasma tube driver and electromagnetic discharge detector
• 49 transformable SOUNDS across 7 BANKS
• SOUNDS are complex digital synth engines that modulate the PLASMA tube driver to achieve various sounds. The engine building blocks are tube driver pulse width and frequency modulation, sample pitch modulation, envelope time stretch, wavefold, crossmod, suboctave modulation

Analog signal path

• Soft clipping DRIVE circuit
• BASS and TREBLE frequency boost/cut EQ section
• Analog state variable VCF (selectable 12dB/Oct LP or HP) with resonance amplifier
• Analog output VCA
• VCF and VCA are digitally controlled with internal analog control voltages
• Audio output level +/-8V max

Controls

• 6 center Indent SLIDER potentiometers 
• PITCH +/- 1 oct (fine tune and octave settings are also available)
• TIME – envelope time stretch
• MOD – pitch modulation effect
• HARM – harmonic content effect
• FLUX – electric artefact effect
• FILTER – cutoff with and without envelope modulation
• 5 center indent ATTENUVERTERS for CV inputs
• ALT button for accessing the alternative SLIDER functions for FINE TUNE, ACCENT parameters and FILTER RESONANCE
• Manual TRIGGER / GATE button
• CLUTCH button for temporary parameter editing buffer
• Push & turn ENCODER and a 7:7 LED indicator for SOUND & BANK selection, octave select and navigating the settings menu

CV & TRIGG

• 7 CV inputs. One for each SLIDE and 1 assignable MULTI CV input as an additional CV for any of the SLIDERS or BANK & SOUND selection
• Pitch CV 1V/Oct, +/-10V range
• Parameter CV, +/-5V range
• TRIGGER and ACCENT inputs: 2V minimum, rising and falling edge detect.
• 5 TRIGGER input modes: TRIG, GATE, LOOP, OSC, ON/OFF
• 7 ACCENT modes: ACC, DUCK, STARVE, CVFREEZE, JUMP, REVERSE, BURST

Settings options

• 5 TRIGGER modes
• (TRIG, GATE, LOOP, OSCILLATE, ON/OFF)
• 7 ACCENT modes
• (ACENT, DUCK, STARVE, CV FREEZE, PITCH JUMP, REVERSE, BURST)
• MULTICV assignment
• MIDI channel select
• Center pitch select
• Master octave offset
• FILTER mode select
• Auto save of all settings

MIDI

• 3.5mm MIDI IN jack, (DIN5 to 3.5mm adapter included)
• MIDI support: Notes, Velocity, CC panel control, PC BANK & SOUND change, PC settings change, Channel 10 General Percussion Key Map, Pitchwheel, Modwheel
• Potential firmware update via MIDI SysEx
• Proprietary plasma tube driver and electromagnetic discharge detector
