New ADDAC215 Dual S&H+ & ADDAC104 VC T-Networks Eurorack Modules

ADDAC215 Dual S&H+

"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."

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.

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."
