GameChanger Audio PLASMA VOICE User Manual

Quick Links

The PLASMA Voice is a unique synthesizer module that creates sound by sending electrical current
between two electrodes in a xenon-filled gas tube. The high-voltage discharges are converted into analog
audio signal using a specially designed electromagnetic rectifier circuit. The resulting output is a diverse
range of electrifying tones that perfectly capture the character and intensity of the vibrant blue electrical
arc.
The PLASMA Voice utilizes a multitude of complex digital algorithms to modulate various discharge
parameters of the plasma tube and the high-voltage current transformer. These algorithms are organized
as 49 transformable SOUNDS across 7 stylistic BANKS, each offering a distinct character and a unique set
of electrical sound properties that can be further shaped and modulated with 6 performance sliders & CV
inputs.
The module's true power lies in its ability to profoundly modify each SOUND beyond recognition - shifting
across 7 octaves will deeply alter the character of each SOUND, not merely its pitch, and adjusting the
analog EQ & DRIVE section will make a radical change in the final output. There is a variety of powerful
accent modes that allow you to elevate a simple sequence into a dynamic performance with just a basic
trigger generator. Furthermore, the module's oscillator and looping trigger modes let you transform each
SOUND into a powerful high-voltage engine with a fully controllable analog VCA & VCF.

  • Page 1 The PLASMA Voice is a unique synthesizer module that creates sound by sending electrical current between two electrodes in a xenon-filled gas tube. The high-voltage discharges are converted into analog audio signal using a specially designed electromagnetic rectifier circuit. The resulting output is a diverse range of electrifying tones that perfectly capture the character and intensity of the vibrant blue electrical arc.
  • Page 2 The PLASMA tube's driver is controlled by a sophisticated LED ROWS & ENCODER DRIVE & EQ KNOBS digital engine. This engine consists of multiple one-shot Two 7:7 LED indicator rows Soft-clipping and tilt EQ section and looping waveforms, as well as envelopes that controlled by the ENCODER.
  • Page 3 Press TRIGGER and CLUTCH at the same time to enter the button and LED rows). SETTINGS mode (indicated by blinking SETTINGS To exit press ALT. Use the ENCODER to navigate the SETTINGS menu as indicated by SETTING the LED rows. Push the ENCODER to switch rows and turn the ENCODER to select values 1-7.
  • Page 4 MULTICV INPUT ASSIGN The MULTICV input can be assigned to any of the SLIDERS as an additional summed CV input or to SOUND / BANK selection. In case of SOUND/BANK selection incoming CV scans through SOUNDS spanning all BANKS. SOUND selection is quantized to the major scale - each white key corresponds to one SOUND, 1V input corresponds to 1 BANK. + FLUX / SLIDER is used as an attenuverter for MULTICV.
