ADDAC506 VC Stochastic Function Generator - Overview

Published on Apr 9, 2020 ADDAC System

"Inspired and officially licensed from Teia's Stochastic Function Generator which was introduced in 2013 but is no longer available. We used the concept of the early version but completely rebuilt and reprogrammed it's mcu to a fully featured 4 voice 2 stage envelope and slew generator.

DESCRIPTION
This new module + expansion is our take on a different envelope/slew generator. It's a fully featured Quad Analogue Core Envelope Generator and Slew Processor with digital control which also incorporates built in random generators to control the Rise and Fall times.
Covering the full range from short sharp notes to long slow sweeps of up to 6 minutes. Together with the random generators it excels when used for drone soundscapes.
Used as a Slew Processor the random generators act as dynamic modulation sources affecting the rise and fall slew speed.
Fully featured outputs act as encouragement to self-patching creating interdependent envelopes acting in sync.

FEATURES
Four independent Rise / Fall generators with individual timing controls.
Built in random generators for Rise and Fall Time each with Minimum and Maximum controls.
Three gate/trigger outputs per channel: End of Rise, End of Fall plus the standard Rise Gate output.
Two extra CV outputs with the Sum and the Average of all 4 voices cv outputs.
Four trigger inputs for the random engine.*
Four CV random outputs from the random engine.*
Dedicated attenuverters for amplitude and offset of each voice CV output. No more need for external attenuators, offsets and inverters.

* Available through the Expansion Module.

ADDAC217 Gate to Trigger - Overview

Published on Apr 8, 2020 ADDAC System

"Following our T-Networks series we came to realize how important it is to have the right input signal for firing drum modules or envelopes, Gates and Triggers are often looked at as similar signals but at times it really makes a difference and results will change drastically depending if a Gate or a Trigger is fed to the input of such modules.

This led us to develop this simple yet effective Gate to Trigger.
A four channel converter with bypass switch for each channel.

Any input Gate will be limited to a 1ms Trigger."

New ADDAC ADDAC216 Sum & Difference Eurorack Module

via ADDAC System

"There are two equal sections in this module labeled A and B.

This module is a peculiar type of mixer that instead of just summing two input signals (X & Y) it also allows the possibility to subtract the two signals.
It works both for audio and CV signals and hence the possibility to get the diference of two CVs or cancel the phase of two audio signals. The resulting signal, of sum or subtraction, is then routed through a switchable (on/off) full rectification circuit labeled: Absolute. After this the gain of the mixed signal goes through another attenuverter labeled: Amplitude to control the resulting signal gain which, being an attenuverter, also allows the possibility to invert the incoming signal. After the Amplitude comes an AC/DC coupling switch followed by an bipolar Offset knob.

Besides the normal output there’s also an inverted output for each of the A & B sections.
The outputs of section A & B are also summed and sent to the Average Output.

Using a single input, just the X or Y input, the module can also be used as a simple dual Attenuverter & Offset CV processor with full rectification and AC coupling options.

Features:

2 independent sections each with:
2 inputs with gain attenuverters
Amplitude attenuverter and bipolar Offset
Absolute/Bipolar and AC/DC switches
Output and inverted output
2 leds monitor the Output polarities and gain.

Average mix output of both sections"

ADDAC603 VC Triple Bandpass Filter - Step Through

Published on Dec 4, 2019 ADDAC System

"Here's the Overview video for ADDAC603 VC Triple Bandpass Filter

At ADDAC we’ve been in love with Bandpass Filters for a long time! We use them in several different ways but mostly as dynamic equalisers at the end of an audio chain for ever-changing timbral qualities with slow modulations on frequency and volume. Slightly or drastically changing the character of the incoming sound just by controlling a few parameters and adjusting the modulation speed. And while this method is a personal preference of ours while developing such module we soon realised that some features would give it other aural qualities and so we started by adding a dedicated feedback control so that each filter could self-oscillate while making this control independent from the Bandwidth control. Also added an amplifier x3 or x100 at each of the inputs in order to create soft or hard distortions turning it into a controllable 3 band distortion!"

ADDAC215 Dual S&H+ Sample Rate Reducer

Published on Nov 28, 2019 ADDAC System

"This new module should not be judged by it’s size, at 6hp it’s packed with features.

At it’s core it features a noise source and two precision Sample & Holds with 0.01% of maximum deviation from the Input which allows for quantized signals to be sent through without any noticeable detuning or the typical voltage drops over time.

The Sample & Hold sections can also be used as a Track & Hold meaning it holds the incoming input while the Trigger input is ON and lets the input flow to the output when the Trigger input is OFF.
Each section also features it’s own slew processor with a single control over attack and decay and an ON/OFF switch.

The noise signal is normalled to both sections inputs, meaning that without a jack plugged into the Input the sample and hold function will act upon the incoming noise signal generating random CV values.

The [Trigger A Alternate] switch allows to Link both sections so that any trigger input in Trigger A will alternate between triggering the A and B section.

Besides each section outputs there’s also 4 extra outputs: Noise, Difference, Average and Sum. The [Noise] output is coming from the noise source, the [Difference] output is the subtraction of section A minus section B, the [Average] output is the sum of both A plus B and then divided by 2 and finally the [Sum] output is the sum of both A plus B sections.

This module will also be available as a full DIY kit."

You can find an overview and details on ADDAC System's new ADDAC105 4 Voice Cluster here.

Introducing the ADDAC105 4 Voice Cluster - First Audio Preview

Published on Nov 20, 2019 ADDAC System

"Following our ADDAC103 T-Networks this new module is inspired by it’s simplicity. This is a 4 voice Square Oscillator with VCA, FM switch and a slew decay for the incoming Trigger IN. All voices are then sent through a Multimode Filter.

Each voice has it’s own VCA input where any input is accepted (Trigger, Gate, CV) The [DECAY] controls the slew decay applied to the incoming signal, if [DECAY] is fully anti-clockwise then it works as a Mute. The [FM ON] switches activate/deactivate the FM input coming from the previous voice: Voice 1 FM comes from voice 4, voice 2 FM comes from voice 1, and so on, so you can FM all of them in a FM loop.

All 4 voices are summed and sent through a filter with controls over [CUTOFF] with an Attenuverter for the CV input and [RESO- NANCE]. Three filter outputs are provided [LOWPASS], [BANDPASS] and [HIGHPASS]

The [EXTERNAL IN] input can be routed through a jumper on the back of the module allowing the incoming signal to go to:
1. the filter input for processing an external audio source.
2. all of the 4 voices Frequency control allowing for some experi- mental CV control over pitch of all 4 voices at the same time (due to the specificities of the circuit and to keep the module at a low price these inputs are not callibrated to 1v/octave).

This module will also be available as a full DIY kit.

ADDAC104 VC T-Networks

"Following our ADDAC103 T-Networks this new module is also inspired by Twin T-Networks circuits used in many lengendary drum machines. A simple 4 voice module with frequency controls for each of the voices. This new module also features CV inputs with attenuverters for each voice Frequency. Due to the specificities of the circuit and to keep the module at a low price these inputs are not callibrated to 1v/octave.

At each voice input there’s a gate to trigger converter so any input source is possible.
Audio inputs can also be used as an input, in this case and due to the nature of the gate to trigger converter, each voice can be used as very destructive filters.

Features;
4 Voices each with:
Frequency control with CV input and attenuverter Frequency Range Switch, Low/Mod/High
Trigger Input
Audio Output

Summing Mix output with Volume control

This module will also be available as a full DIY kit."

New ADDAC System 103 T-Networks

Published on Jun 20, 2019 DivKidVideo

"Here we have the vintage, analog / analogue T bridge, twin T (it get called multiple things) circuits that make up some classic circuits in well known drum machine and electronic percussion of yesteryear. This circuit has been tweaked and modded and brought into Eurorack as a simple 4 voice percussion module as the T-Networks from ADDAC System. It can be punchy yet soft clean percussion, or ripe for percussion and FX, kicks, toms, claves, short rimshot like snaps and more. You can audio rate trigger/input for some interesting destructive filtering too.

5 new Eurorack modules from ADDAC System // Superbooth 2019

Published on May 27, 2019 DivKidVideo

"I've had the pleasure of checking out some of these new modules already including the Heart Sensing (video link below) and the Triple Band Pass. The new oscillator looks great, I like the on board mixing and 3 controls for pitch! Having coarse, octave and fine will make it super quick and easy to tune and play. The quad T-Network with the 4 basic twin T percussion sounds I think is going to be really powerful in not much space for kicks, toms, tablas and clave like sounds. Finally the Tube Filter ... OOOOH that Tube filter! It's a licensed remake of the Gotharman TubaZ with loads of added extras."

HEART RATE PWM // Modulation from your heart with the ADDAC 307

Published on May 6, 2019 DivKidVideo

"Control your modular with your heart rate LITERALLY and get some heart rate PWM / Pulse Width Modulation in your life. Literally like a direct heart to Nick Batt module in Eurorack.

The ADDAC 307 Heart Sensing module comes with a heart rate monitor you can connect to your finger or earlobe and you get your heart rate as a gate signal on the trigger output. You also get an envelop follower and inverted envelope follower style output which generates a slew/lag version of the gate. You can adjust rise and fall times, adjust amplitude and offsets and take the inverted and normal version outs around your system."

"The Intuitive Quantizer is perhaps the most powerful quantizer module in Eurorack. With four independent inputs and outputs for melodies there is plenty of pitch locking for your voices. The intuitive name comes from the ease of programming as you are supplied with a keyboard represented in push buttons on the panel. Each channel has a trigger in and out and presets can be saved for your favorite scales! This module is in great shape with little to no rack rash."

ADDAC System 306 VC Transitions - Performance orientated macro control for Eurorack

Published on Feb 5, 2019 DivKidVideo

"So here we have the absolutely lovely little ADDAC System 306 VC Transitions Eurorack module. It creates "macro controller" type performance orientated control with some simple patching and set up. There's 5 offset voltage outputs that can have a minimum (or starting) voltage and then a range of voltage added on top. Want to move from 1V to 3.5V or from 10V back to 7V? Then this does that easily and it does it with 5 individual outputs all scaled and trimmed to suit their sources controlled by a slider on the bottom of the module. That slider is also CV controllable turning the module into a 1 CV to 5 CV output with each of the 5 CVs related in movement but individual in their ranges and movement. It works right up to audio rates too.

New ADDAC 812 Meter Eurorack Modules

Published on Feb 4, 2018 ADDAC System

ADDAC812A

Stereo/dual audio meter with buffered thru outputs for each channel. 11 pairs of LED indicate the audio levels up to 10V.

Green lights go up to 5V, yellow almost reach 10V and 10V is red, indicating peaking.

Since modulars use Voltages we decided to use Volts and not dBs as a measurement that makes more sense for our favorite system!

ADDAC812V

Dual voltage meter with buffered thru outputs for each input.

11 pairs of LED indicate the voltage levels from -5V to +5V.

A quick and easy way to check your voltage levels and to add a small pseudo-oscilloscope in your system.

ADDAC812VU

Stereo/dual VU metering module with buffered thru outputs for each channel.

An additional switch turns the beautiful lamps behind the VU meters off, in case your rack is running low on power!

A couple trimmers on the back of the module allows the user to define the VU range of each channel independently.
