4.6 VOLT

VOLT is essentially the expanded, multi-layer version of VOLT mini. It consists of two identical layers called Part 1 and Part 2. Each part contains two identical oscillators (OSC A and OSC B). Because the controls for each oscillator and each part are the same, the following descriptions apply to all of them.

Top bar controls

• Simple / Advanced: Toggles between the basic view and deep modulation view.
• Global Solo: Restricts the instrument to playing one note at a time (monophonic).
• Glide: Adjusts the time it takes for the pitch to slide between notes.
• Part 1 / Part 2 Buttons: Switches the entire interface to show the settings for the first or second sound layer.
• OSCMIX: A slider that sets the volume balance between Part 1 and Part 2.
• Mixing Modes: Determines how the two Parts interact: 
  • A + B: Standard mixing where both sounds are added together. 
  • A x B: Multiplies the signals (Ring Modulation) to create metallic, clashing tones. 
  • A ^ B: Forces Oscillator B to hard-sync to Oscillator A for aggressive, "tearing" sounds.

OSC A & OSC B (Simple View) 

• Waveform Icons: Selects the fundamental sound shape: Sine, Triangle, Sawtooth, Square, or Noise.
• Octave: Moves the pitch up or down in 12-semitone jumps.
• Coarse: Moves the pitch up or down in semitone steps.
• Shape: Morphs the geometry of the waveform. For example, on a Sine wave, increasing this makes the sound more like a Sawtooth wave.
• Quality: Adjusts the spectral detail and digital clarity of the oscillator.
• Unison: Layers multiple internal copies of the sound to create a thicker effect.
• Detune: Changes the pitch distance between the layered unison voices.
• Stereo: Spreads the unison voices across the left and right speakers.
• Mix: Sets the output volume level of the oscillator.
• Waveform Window: Displays a real-time visual of the resulting audio wave shape.

OSC A & OSC B (Advanced View) 

• Oscillator Sliders: This section features the same controls found in the Simple view (Octave, Coarse, Shape, Quality, Unison, Detune, Stereo, Mix), but represents them as sliders for more precise adjustment.
• Fine: Adjusts the pitch in micro-increments (Cents) for very subtle tuning.
• Gain: Sets the level the oscillator signal.
• Pan: Positions the oscillator sound specifically to the left or right in the stereo field.
• Envelope Graph: A visual ADSR (Attack, Decay, Sustain, Release) window used to shape how the filter brightness moves over time. You can change the shape by dragging the dots directly on the graph, or by clicking and dragging up/down on the millisecond (ms) and decimal numbers below the graph for more precise control.
• Modulation Sliders (Pitch, Shape, Detune, Level): These four sliders determine how much the Envelope Graph moves those specific parameters.
• Velocity Slider: Sets how sensitive the envelope modulation is to the force used when playing a MIDI note.
• Oscillator LFO Section: A Low Frequency Oscillator that adds steady, pulsing movement to the sound.
  • LFO Mode: Sets behavior to Free (runs constantly), Retrigger (restarts on every new note), or Oneshot (plays through its cycle only once).
  • LFO Waveforms: Selects the movement shape (Sine, Triangle, Square, Sawtooth, or Random).
  • Rate / Amp / Delay: Controls the speed of the wobble, the intensity of the wobble, and the time before the wobble starts.
  • Targets (Pitch, Shape, Gain, Pan): Four sliders that set exactly how much the LFO wobbles those specific oscillator settings.

FILTER Tab 

• Filter Type Dropdown: Selects the specific filter architecture to shape the sound.
  • LPF12 / LPF24: Low Pass Filter. Passes frequencies below the cutoff point. The 24 version provides a steeper slope for a more aggressive cut. 
  • HPF12 / HPF24: High Pass Filter. Passes frequencies above the cutoff point. 
  • BPF12 / BPF24: Band Pass Filter. Passes a narrow range of frequencies centered on the cutoff point. 
  • Noise: Routes a noise generator through the filter circuit.
• FC (Filter Cutoff): Sets the frequency where the filter starts cutting the sound.
• Q (Resonance): Emphasizes the frequencies at the cutoff point, creating a sharp tonal peak.
• Drive: Adds harmonic warmth and analog-style saturation to the filter.
• Filter LFO Section: A dedicated Low Frequency Oscillator for automatic movement of the filter brightness. --
  • LFO Mode: Sets the cycle behavior to FREE (runs constantly), RETRIGGER (restarts on every new note), or ONESHOT (plays its cycle only once). 
  • LFO Waveforms: Selects the movement shape (Sine, Triangle, Square, Sawtooth, or Random). 
  • RATE: Adjusts the speed of the filter wobble. 
  • AMP: Adjusts the intensity of the effect. 
  • DELAY: Sets the time elapsed before the modulation begins. 
• Filter Envelope: Provides time-based automation for the Filter Cutoff frequency. 
  • Envelope Graph: A visual ADSR (Attack, Decay, Sustain, Release) window used to shape how the filter brightness moves over time. You can change the shape by dragging the dots directly on the graph, or by clicking and dragging up/down on the millisecond (ms) and decimal numbers below the graph for more precise control. 
  • LEVEL: Adjusts the intensity of the envelope's effect on the cutoff frequency. 
  • VELOCITY: Determines how much the key strike force influences the filter movement.

AMP Tab 

• Level Slider: Sets the master output volume for the currently selected Part.
• Amplitude LFO Section: Adds pulsing volume movement to the instrument.
  • LFO Mode: Sets behavior to FREE, RETRIGGER, or ONESHOT.
  • LFO Waveforms: Selects the volume wobble shape.
  • RATE / AMP / DELAY: Adjusts the speed, intensity, and timing of the volume modulation.
• Amplitude Envelope: Shapes the final volume (loudness) evolution of the sound. 
  • Envelope Graph: A visual ADSR (Attack, Decay, Sustain, Release) window used to shape how the filter brightness moves over time. You can change the shape by dragging the dots directly on the graph, or by clicking and dragging up/down on the millisecond (ms) and decimal numbers below the graph for more precise control.
  • LEVEL: Adjusts the intensity of the volume envelope. 
  • VELOCITY: Determines how much the key strike force affects the final volume.
