ADDAC 103 - T-Networks

Inspired by Twin T-Networks circuits used in many lengendary drum machines we developed a simple and straight forward 4 voice percussion module with frequency controls for each of its voices. 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. Here is a DivKid video about it on YouTube.

 

Features:
4 Voices each with: Frequency control, Frequency Range Switch, Low/Mod/High, Trigger Input, Audio Output, Summing Mix output with Volume control
 
Technical details:
6HP, 2.5 cm deep
40mA +12V / 40mA -12V

Panel color: black

 

This is a Do-It-Yourself kit, not an assembled module. Building instructions can be found here.

DIY level: easy/medium. Most SMT parts are pre-populated, THT parts and bigger SMT parts to be soldered.

ADDAC 200PI - Pedal Integrator

This small utility is the pedal's lover best friend, it allows 2 diferent chains of pedals to be independently connected to your synth. The Send channels attenuate the synth level to instrument level. The Return channels amplify the signal from instrument to synth level. Here's a demo video about the module.

ADDAC 213a - Eurorack Bridge

The first modules from our Eurorack Bridge system! A pair of ADDAC213As acts as a simple one-cable bridge between different cases. By itself the ADDAC213As can send/receive 8 CV or audio signals between your cases, but can be expanded to bridge two cases for up to 24 signals at the same time. Use a pair of ADDAC213As to send & receive 8 CV or audio signals between distant points in your case, between two separate cases, or between your case and a friend's case.

 Less clutter, less spaghetti, faster connection!

 There’s nothing better than being able to connect that controller skiff with just one cable to your main system. At a gig, in the studio, when jamming with a friend, give yourself a gift by grabbing a pair of ADDAC213As.

 The modules can be installed in normal position or a 180 degree position to fit any need and any case design. Here's a video about ADDAC213A & B.

 

Expansion possible by the ADDAC213Bs:



Each ADDAC213A module can be connected through a ribbon cable connection on its backside with up to two ADDAC213Bs. Each ADDAC213B module added expands the channels options of the ADDAC213A by adding 8 more channels.

With two 2 ADDAC213Bs connected to each ADDAC213A module, you’ll have a total of 24 channels going between your cases with a simple one-cable bridge.

Between the ADDAC213A pair and the ADDAC213B, your cases never looked so elegantly connected together!



 

The ADDAC213As are always sold as a pair of 2 modules and an included 50cm ribbon cable.

Width: 6 HP

Depth: 2,4 cm

ADDAC 213b - Eurorack Bridge Expansion

The ADDAC213B is the second pair of modules from our Eurorack Bridge system!

 A pair of ADDAC213Bs can be used in standalone to send/receive 8 CV or audio signals between different points inside the same case or as an expansion to the main pair of Eurorack Bridge modules, the ADDAC213As.Here's a video about ADDAC213A & B.

 

Standalone use

: Two ADDAC213B modules can be connected to each other with the use of a single ribbon cable and then used inside a case to carry signals between distant points without the need for long cables. Less clatter, less spaghetti, more space of your fingers on those knobs! A single pair can send & receive up to 8 CV or audio signals between different points in your case at the same time. The modules can be installed in normal position or a 180 degree position to fit any need. 

Do you have modules that you often use together in different areas of your case? Would you prefer that each row’s cables don’t mingle with cables from other rows? Grab yourself a pair of ADDAC213s.

 


As an Expansion to an ADDAC213A

: Each ADDAC213B connected to the backside of an ADDAC213A adds 8 more channels to the main bridging functionality of the ADDAC213A.

 Up to 2 ADDAC213B can be connected to an ADDAC213A module, expanding the bridging between two difference cases to a total of 24 channels. If you’re looking for a simple one-cable bridge between your various cases, then look no further than the ADDAC213A.

 Between the ADDAC213A pair and the ADDAC213B, your cases never looked so elegantly connected together!

 

ADDAC213Bs always come in pairs. Price is for a pair of modules (2 modules) including two 50cm ribbon cables. Only one is used to connect the two ADDAC213B together but two are necessary when connecting the two ADDAC213B to two ADDAC213A.

ADDAC 214 - VC Rotator

This is our VC Rotator, a stepped routing module for any type of signal (audio, cv, gate, trigger...). Similar to a VC switcher but in this case there's the same number of inputs than outputs so, instead of 4 to 1 or 1 to 4, this module is always 4 to 4 but it can be patched for 2 to 2 and 3 to 3 step actions. All four inputs get routed to the four outputs depending on the CV and Clock controls and are divided into 4 routing steps:

1. routes all inputs to the same number output: 1:1, 2:2, 3:3, 4:4

2. routes all inputs to an offset of 1: 2:1, 3:2, 4:3, 1:4

3. routes all inputs to an offset of 2: 3:1, 4:2, 1:3, 2:4

4. routes all inputs to an offset of 3: 4:1, 1:2, 2:3, 3:4

Direction determines if the clock input goes forward or backwards.

Going forward it can be set to 2-3 or 4 steps using the Rotate knob offset, going backwards always sync to 4 steps even if offseted by the Rotate knob. For 2 & 3 step action input 1 is normalled to input 3 and input 2 is normalled to input 4. Reset resets the internal clock to the first step. Pendulum, external sequencing or any complex CV actions can be achieved using the CV input and dedicated attenuverter. 4 leds monitor which input is routed to output 1.

4 Inputs

4 Outputs

Direction Switch

CV Rotate with Attenuverter

ADDAC 304 - Manual Gates

With the ADDAC304 Manual Gates you'll be getting 8 manual gates (0 +5v) in a nifty package - a perfect way to perform on and control your modular system. The ADDAC304 comes with an interesting twist: 4 out of the 8 available gates can act as momentary switches, outputting the signals in their respective inputs when each gate’s button is pressed. Here's a video about the module.

 

FAQ:

Q: Are the buttons momentary? Will the module send a gate-high signal for as long as the button is held down?

 A: Yes! The ADDAC304 uses momentary switches (check the ADDAC305 if you want toggle switches instead). The module will output a +5v signal for as long as the button is held down, and when released it will output 0v.

 

Q: Will the module output gates when nothing is connected at the inputs?

 A: If a jack is plugged in an channel which has an input, then when you press the button the incoming signal will be output instead. If there is no input then the channel behaves like all other channels, firing +5v when pressed and 0v when not pressed.

ADDAC 703 - Discrete Mixer

Here's the second module of our 700's Heritage Series. Inspired by Moog CP3 mixer, this is a totally discrete analog mixer and it's not, by any means, your standard breakfast mixer, although it can behave like one. This is a wolf in sheep's clothing. Despite its harmless looks there's a dark snarly soul behind that panel that wants to take your sounds into a realm of gritty gnarly growls. Here are 2 videos about the module: video 1 and video 2.

 

Features:

4 Independent channels with input jack and volume knob

1 Feedback/gate knob

Master output volume knob

6 Front panel trimmers allows user to adjust the Input resistor trimmer for each channel, feedback and master output

1 Front panel trimmer allows to adjust the mix Bias
