    • 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:

      • 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.

  • width: 8HP
  • depth: 21mm
  • power: +12V @52mA, -12V@17mA, +5V@0mA

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.
