Klavis Twin Waves is an extremely fully-featured voltage-controlled dual VCO/LFO

The two oscillators can independently be set as either a VCO or LFO.

Features in VCO mode:

  • V/Oct tracking over 10 octaves
  • Through zero oscillator
  • Sub-octave output
  • Linear FM at audio rate
  • Hard & soft synchronization
  • Quantizer with various scales
  • 9 Algorithm-based synthesis types:
    • Wave shaping
    • Phase modulation
    • Phase positioning of multiple waves
    • 5 stacked oscillators in tunable unison
    • Self-sync with phantom oscillator
    • Additive synthesis (7 waves)
    • Variable bit reduction (bit-crushing)
    • Ring modulator with its own 2nd oscillator
    • Noise with LPF, BPF, or resonant filter

Features in LFO mode:

  • Simultaneous signal and trigger outputs
  • Wave synchronization
  • Clock controlled rate with multiplier and divider
  • CV and knob control of output level
  • Algorithm based wave engine with a selection of:
    • Wave shaping
    • Phase modulation
    • Random levels and vectors (also Brownian)
    • Randomly spaced triggers and waves

Other features include:

  • Display with contextual icons and instant reminder help text
  • LEDs indicating potentiometer vs. value matching, switch settings and output levels
  • Automatically saved settings for instant recall at power on
  • Firmware update via a simple audio file

Firmware 1.11 main additions

  • Audio algo selection by CV
  • Quantizer’s base note settable + CV control
  • Relative/Absolute modes in Self-Sync algorithms
  • Enriched LED feedback
