The MKII version does everything the original Twin Waves did and more.
This is why all links to reviews, comments and videos of the original version are here.

Twin Waves MKII

Voltage-controlled Dual VCO/LFO/random
  • Two oscillators independently set as VCO, LFO, or random generator
  • 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 types among:
      • Wave shaping
      • Phase modulation
      • Phase positioning of multiple waves
      • Up to 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

    • External wave synchronization
    • Clock controlled rate with voltage controlled 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
  • Display with contextual icons and instant reminder help text
  • LEDs indicating potentiometer vs. value matching, switch settings and output signals
  • Automatically saved settings for instant recall at power on
  • Firmware update by playing an audio file via the front panel
  • Compact and skiff-friendly module

This MKII evolution brings a redesigned layout, additional knobs for more hands-on fun and semi-modular cross-patching between sections.
All of the original features are present: a top selection of synthesis techniques, each with their key parameter directly at hand, enriched by a full set of complementary features.
More than ever the Twin Waves is versatility at its best.


Version 1 vs. MKII

What is kept and what is new?
  • Same width (8hp)
  • Same price
  • All TW v1 capabilities and features retained
  • Three dedicated modulation gain pots
  • Semi-modular cross-section patching

Whereas the original Twin Waves required +/-5V signals to benefit from full scale modulation, the new version requires less and has gain knobs for all 3 modulation inputs.
These gain knobs are even more beneficial given that a normalling of the outputs to the other section's modulation input(s) allows creative results without requiring extra patching.
This offers an easy and creative access to "complex oscillator" fun and cross modulation craziness..

Using the outputs does not break their normalling; this avoids using a "multiple" when the output signal should go both inside and outside the module.

The dedicated Square1 output of the first oscillator is normalled to the global sync/clock input. This allows synchronizing the second oscillator both for audio and LFO/random purposes.


The Twin waves was mentioned in the following query-posts on Muffwiggler:
  • Standout modules of the last couple of years?
  • What is the most FUN module you own?
  • What are you using for LFOs?
  • Most unique digital VCO you've heard?
  • What's your favorite non-drum percussion module?
  • Must have VCO max 12HP
  • Must have VCO max 10HP

I'm not sure what development in the module contributes to this aspect, but it produces some of the fullest/fattest sounds I've heard from a digital oscillator, not to mention it's packed with features and very well thought out.
The FM between oscillators sounds different than everything else in my rig....sputtery and juicy when both are in audio range, and spazzy when LFO FM's audio rate.
Makes a chap wanna get a second one.
Best digital oscillator(s) I’ve ever used.
I love my Twin Waves!
From the first moment, it has become the definite go-to VCO in my rack, and if I feel the need to double up one particular vco module, it'll be that one.
I'm so glad I got this...it's an absolute gem.
It's a monster (a dual monster).
Man this thing looks so nice, great features for a very reasonable price.
The price/performance/features/HP ratio is just fantastic, IMHO.
I use mine in LFO mode so often that I sometimes forget how amazing the VCOs are.
Thank you, Klavis, for your excellent work; especially Twin Waves, which I think is worth its price and size for its LFOs alone.
I'm not really a fan of shared knobs on digital modules but the Twin Waves implements this between its two oscillators in a very fluid and ergonomic manner.
The symbols it uses for each waveform algorithm are also quite well designed; they're all pretty self-explanatory but after a single read through of the manual to be sure of the specifics I was good to go.
I own the Twin Waves and I'm super impressed with the build quality.

Biggest value module you own?

That's the question a Muff Wiggler post asked to the community.
Name your most valuable module whatever the type.
The Twin Waves was put in the spotlight several times.

Klavis Twin Waves for all of the function that it brings in a small space.
Clever thing.
+1 for Klavis Twin Waves.
It can do so much and it's 2 in 1.
Incredible value especially in reduced size racks and for melody use.
For oscillators... probably the Klavis Twin Waves.

Eric from Klavis interviewd by Max from Prognosis

Using a single Twin Waves as a complex oscillator.
In the various examples, the FM is not used.
Instead, synchronization, time reversal and wave shaping are done from osc2 to osc1.
If needed, perfect pitch relation without altering the timbre can be achieved by (internally) deriving the V/Oct for both osc from the osc1 input jack.

The video is quite old, with a now obsolete firmware.
In the meantime, several synthesis algorithms were added or improved.

A nice piece with the Twin Waves as the sole sound source.
Allow it a minute to start and wait for the bass line at 2:20 ;-)

Audio clips

Set as dual VCO in OFFSET mode + SUB out, all mixed and sent to a Korgasmatron (filter modulated with a LFO sync of a second Twin waves using browian vectors algo.
  • VCO1: Unison SAW (note = C), Quantizer = minor
  • VCO2: Additive Odd (note = F), Quantizer = minor, harmonic content modulated from a second Twin waves in LFO mode with Brownian vectors algo
Overall FX: Black hole DSP + Z-DSP

  • First section VCO: Supersaw with phase spread driven by second section's LFO
  • Second section as LFO: Sine in Sync mode with mult/div ratio manually tweaked. Sent to VCO param + Korga for filtering.
Modcan Dual LFO introduced in the second part.

Changing algo on the fly manually.
( CV control of Algos was not available initially! )

  • Beats (Analog Rythm) and bassline (Twin waves + SSF Pole ZERO)
  • Sound effects (Twin waves + SSF MMF)

Twin Waves going through a WMD MMF VCF, is doing the bass line duties on both of these.
It is using the Unison Saw algorithm.

First minute is Twin Waves' output A in detuned saw algo.
Output B appears about a minute later in the self-sync sine algo.
Then the sub out comes in for the last minute to beef things up a bit.
