Twin waves Klavis Eurorack

Dual VCO/LFO

The driving idea behind the Twin waves voltage-controlled dual oscillator/LFO is to offer two interesting oscillators in a skiff-friendly and compact size. To achieve that challenge, we built the product’s architecture on the concept of pre-defined algorithms, where the most useful configurations and their matching parameter are ready to use.

Two oscillators independently set as VCO or LFO
Features in VCO mode:
- V/Oct tracking over 10 octaves
- Through zero and linear FM
- Sub-octave output
- Hard & soft synchronization
- VCA control and CV algorithms selection
- Quantizer with various scales
- 20 algorithm-based synthesis to choose among:
  > Waveshaping
  > 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 CV-controlled multiplier and divider
- CV and knob control of output level
- Algorithm based wave engine with a selection of:
  > Waveshaping
  > Phase modulation
  > Random levels and vectors (also Brownian)
  > Randomly spaced triggers and stretched waves
Display with contextual icons and instant reminder help text
