R_WARE - SPLINECURVE

Smooth Spline-Based Oscillator/LFO/Envelope Generator/Waveshaper!

A true powerhouse of a module! SplineCurve combines an intuitive way of drawing smooth, continuous waveforms with versatile phase and frequency manipulation.

Craft your own unique waveforms that provide the sonic foundation for your unique sound! Twist and bend the shape to your hearts content and your ears delight with the array of phase distortion options. And all of that with pristine sound quality with up to 8 times oversampling!

Use SplineCurve as a draw-able LFO that stays smooth even at the wildest shapes! Easily transform SplineCurve into a one-shot envelope that provides unique trigger-able modulation!

You can even use SplineCurve as a highly customizable waveshaper that shapes your signals with force and precision!

Manual

Controls

• PITCH CV

  • Pitch CV input for 1V/oct signals to tune the Oscillator/LFO/Envelope Generator frequency/timing (exponential response, adding 1V is doubling the frequency/halfing the time)

• OCT and FINE knobs (only available in FREE MODE)

  • Set the octave and fine tuning (in cents) of the oscillator
  • In Oscillator mode the base tuning is C2 (ca 65Hz)
  • In LFO/ENV mode the base tuning is C-5 (ca 0.5Hz)
  • In Waveshaper mode the whole pitch/frequency section is disabled

• RATIO TOP and BOTTOM knobs (only available in SYNC MODE when LFO or ENV is selected)

  • Set the frequency of the LFO/Envelope generator as a tempo-synced ratio

• OS FACTOR (only available in Oscillator/Waveshaper mode)

  • Set the oversampling factor to improve sound quality at the expense of increased CPU consumption

• SYNC MODE (only available in LFO/Envelope mode)

  • Choose between free or tempo-synced frequency settings
  • NOTE: in FREE mode the base tuning is C-5 (ca 0.5Hz). Use the TZFM knob to add to/subtract from that base frequency

• MODE

  • Set the current mode of operation
    • OSC - SplineCurve works as a versatile, high-quality, draw-your-own-waveform oscillator with extensive modulation and tone shaping options
    • LFO - All of the Oscillator goodies, but without the oversampling. Can be tempo-synced.
    • ENV - Similar to LFO mode but as a one-shot when triggered through the RETRIG button or RETRIG CV
    • SHAPER - Turns SplineCurve into a neat waveshaper! Draw your own distortion curves! Signal input is the PHASE CV. Pitch/Frequency controls/CV are disabled but all other shaping options are still available.

• FADE IN

  • Create a fade in window to smooth the onset of the curve

• FADE OUT

  • Create a fade out window to smooth the end of the curve

• LINK

  • Links the first and last node of the SPLINE to create a smooth curve
  • NOTE! It is recommended to have this enabled in Oscillator mode to mitigate aliasing!

• POINTS

  • Set the number of points used to create the SPLINE
  • More points yield more complex waveforms

• RAND

  • Generate a new random curve!

• RETRIG

  • Reset the phase to make the oscillator restart at its beginning (leftmost side in the display)

• PHASE

  • Phase Modulation to modulate the phase of SplineCurve
  • NOTE! In Waveshaper mode the PHASE CV is the signal input!

• PD X

  • Phase Distortion along the X Axis (horizontal phase distortion)

• PD Y

  • Phase Distortion along the Y Axis (vertical phase distortion)

• PD S

  • Phase Distortion Strech and Squeeze (phase distortion to move the waveform inwards/outwards)

• PD B

  • Phase Distotion Bend (distorts the phase with a power function)

• TZFM

  • Through-Zero Frequency Modulation modulates the frequency of the oscillator linearly and inverts the oscillator's direction for negative frequencies
