Logic for Sound Design

TWO BITS

Dual logic processor with chaining and CV functions
Two dual-input logic processors
15 different functions
Simultaneously available normal and inverted outputs
LEDs on all outputs
Chaining optionally inverted by dedicated button with LEDs
Chaining does not waste any input or output; an additional virtual input is created in the second section
Functions with duration, voltage, percentage, and ratio are user editable.
User settings are stored automatically
Random pass, voltage comparator, clock mult/div and delay line functions allow CV control
White LEDs next to the pots confirm the matching of knob position and function
The outputs can be Ored by simple shorting in a multiple
Firmware upgradeable by playing an audio file
Low consumption, skiff-friendly & compact module
Complements Klavis’ Logica XT with a varied feature set

Note: the focus drifted on me while I recording—so frustrating!—so it gets a bit soft, but I think it’s probably still watchable."

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

Koma Komplex Skip Step Demo II (a different setting)

Published on Apr 6, 2018 Martin Doudoroff

"At the risk of redundancy and confusion, here’s a different experiment using the skip step jack to advance the phasing between two simple sequences. In this version, the first Mode setting on sequencer B is enabled so that phasing advances are not temporary—this is a more typical phasing arrangement than in the previous demo. (I got confused by the documentation, which gets the settings backwards.)

Sequencers A and B are connected to basic VCO/VCF voices; this time, I’m lazily using Sequencer C for a simple bass line (gate only—pitch is recycled from Sequencer A). Everything is clocked by a Gatestorm. The Gatestorm is also generating the gate to trigger the skip step."

CONTROL Demystifying Maths 101 Set for February 23 in New York

via CONTROL

"Control is pleased to present "Demystifying Maths 101," an introductory intensive on the Make Noise Maths lead by Martin Doudoroff.Are you baffled by or afraid of Maths? Is Maths just sitting in your rack, neglected? Or are you just curious what the fuss is about? We’ll straighten all that out for you in this introductory workshop on one of the most versatile tools in Eurorack. Choose Session A (5-6:30pm) or Session B (6:30-8pm). Feel free to B.Y.O. Maths, but it is not required. The class will look at the basic topology and functionality of Maths with a focus on: simply understanding/demystifying the discrete components of Maths; bread-and-butter usage (envelopes, slew, mixing/attenuation/offset); and if time allows, getting into some Serge-style patch programming.The class will take place on Friday, February 23rd at Control, Brooklyn, NY. Please choose one of the two sessions A or B. Due to the desire to keep this workshop seminar-like in nature, seating is limited. For this reason, you will be asked to pay a refundable $5 deposit in order to reserve a seat. The charge will be refunded upon arrival. No refunds will be issued for no-shows."
