Klavis Quadigy as an expressive ADSR

Published on Oct 18, 2019 Martin Doudoroff

"An exhaustive exploration of the ADSR features and behavior of Klavis Quadigy Quad Programmable Envelope Generator for Eurorack modular synthesizers.

Addenda:
• I didn’t realize until after the video was done that the PUNCH parameter is considered part of ATTACK for the purposes of the FULL ATTACK mode; so, with FULL ATTACK turned on, you’ll get at minimum the full attack and punch of the envelope; good to know
• I should have clarified that the time value of the HOLD parameter is relative to gate/trigger on, not relative to the end of DECAY
• I should have clarified that the HOLD parameter can be used in conjunction with gates as well as with triggers; with gates, the HOLD parameter effectively sets the minimum duration of the envelope (not including RELEASE)"

"The Quadigy is a complex envelope generator focused on live play. The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage. This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

Quad 7-stage envelopes
Pre-delay
Hold
Attack
Punch
Decay
Sustain
Release
Continuous curve shape setting
Inversion
Independent output level
Cycle capability with auto fit-to-clock
Elastic time stretching
5 internal clocks with tap tempo
External clock control
Multiply/divide and offset
Individual cycle ext. control
32 presets with naming
External preset control via CV/Trig
Simultaneous 156-point CV matrix
Morphing on presets and CV Matrix
Multi-editing for polyphonic uses
Live mode for easier/safer control
Graphical display
Real-time envelope stages LED indication
Current state retained over power cycle
Easy firmware update via an audio file
Skiff-friendly and compact module

Klavis Twin Waves Dual Oscillator

Published on Aug 24, 2017 Perfect Circuit Audio

"For this patch, the Malekko Voltage Block is the main pitch sequencing brain, with the QCD as the main rhythmic sequencing brain. Two QCD clocks are being sent to trigger both channels of Maths, which then control the volumes of Oscillator 1 and 2 of the Twin Waves via Tangle Quartet. The Parameter CV inputs for both Oscillator 1 and 2 are coming from independently LFOs produced by two Intellijel DixieII+s. Oscillator 1 is providing the melody, with Oscillator 2 providing the bassline. There is an extra kick, made by the Doepfer Thru-Zero VCO, and a Snare, made by Mutable Instruments Braids. The whole mix is then split and sent as an FX send through the Belgrad filter from XAOC, and the Alright Devices Chronoblob delay. In the third patch, the bassline is sent through the MiniMod VCF to demonstrate how filters can respond to its high harmonic content.

Eurorack demo: Klavis Twin Waves & Vermona twinVCFilter

Published on Jul 12, 2017 Nick Herman

"A compilation of short demos showing off some of the characteristics of the Klavis Twin Waves (actually just oscillator 1 and it's sub oscillator!) through various parameters and modulation of the new Vermona twinVCFilter, which is one of the most glorious and flexible filters I've come across. With all the cv inputs, you start to approach ADDAC filterbank territory..but it's smoother, and cheaper."

TWIN WAVES by KLAVIS - dual oscillator review (ENGLISH VERSION)

Published on Mar 6, 2017 Marcin Staniszewski

"This is a review of TWIN WAVES dual oscillator module - made by KLAVIS (www.klavis.com). The review also appears in April 2017 issue of "Estrada i Studio" - biggest Polish monthly magazine devoted to music production and studio equipment."

"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 oscillator
Sub-octave output
Linear FM at audio rate
Hard & soft synchronization
Quantizer with various scales
Algorithm-based synthesis to choose among:
> 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
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"
