Twin waves

Voltage-controlled Dual VCO/LFO
  • Two oscillators independently set as 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
    • 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
  • 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
  • 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 by playing an audio file via the front panel
Firmware 1.11 main additions
  • Audio algorithms selection by CV
  • Quantizer's base note settable + CV control
  • Relative/Absolute modes in Self-Sync algorithms
  • Enriched LED feedback
Firmware 1.13 main additions
  • New scales in the quantizers
  • Quantizer's scales full names in the scrolling help
Firmware 1.16 main additions
  • New CV mode: BZX FM - Bipolar thru-zero crossing FM

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.

I'm so glad I got this...it's an absolute gem.
Man this thing looks so nice, great features for a very reasonable price.
It's a monster (a dual monster).
The price/performance/features/HP ratio is just fantastic, IMHO.

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.
