4ms - Percussion Interface & Expander

available

The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source.Converting microphone, instrument, line and modular signals into CV and clock/gate signals, the PI and PI Expander are suited for synchronizing sequencers or other modules to the rhythm of an audio track or live percussion. The modules can simultaneously be used as a pre-amp for microphones or line-level signals, while generating inverted envelopes useful for side-chaining. The PI module contains all the core functionality and can be used without the Expander to conserve space. The Expander requires the main PI modules and adds three gain stage options, a modular-level audio output jack, a 1/4" (6.35mm) input jack, and envelope attenuation capabilities. The two modules are only sold together, they are not available separately.Features:• Sensitivity knob, Low/Medium/High gain switch, and clipping LED• Sustain control to prevent misfires, increase gate length, and control the envelope• Envelope decay control• Non-inverted and inverted envelope outputs, useful for side chaining• Four envelope outputs: two attenuated with independent attenuators, and two non-attenuated• Envelope following or generation modes• Gate output for clocking sequencers or any unit with a clock or trigger input• Compatibility with drums, pads, samplers, microphones, piezos, drum machines, etc.• 1/8" or 1/4" input jack (6.35mm)

ADDAC System - 214 VC Rotator

available

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 as 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, 4:42. routes all inputs to an offset of 1: 2:1, 3:2, 4:3, 1:43. routes all inputs to an offset of 2: 3:1, 4:2, 1:3, 2:44. routes all inputs to an offset of 3: 4:1, 1:2, 2:3, 3:4Direction 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.Features:• 4 Inputs• 4 Outputs• Direction Switch• CV Rotate with Attenuverter• Clock and Reset Inputs• 4 Monitor LedsDIY-Kit-Type:SMD-Kit-2.

ADDAC System - 216 Sum & Difference

available

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 allows for 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.DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 306 VC Transitions

only 1 left

ADDAC306 is a 5 channel multi-directional CV generator.You can think of it as a "sweet spot" controller, or a hands-on way of transiting from one state to another.Each of the five channels has MINIMUM, SPAN and DIRECTION controls, a common CV IN and a common TRANSITION CONTROLLER slider.MINIMUM sets the minimum channel voltage.SPAN sets the voltage range of the channel.It essentially sets the maximum voltage that can be output from the channel, relative to what the current channel MINIMUM is. For a given SPAN value, if the MINIMUM voltage is changed then the maximum voltage output from that channel will also change respectively.DIRECTION sets whether the voltage transition for each channel goes from MINIMUM to maximum, or maximum to MINIMUM.The TRANSITION CONTROLLER slider controls the transition from the minimum value (A) to the maximum value (B) or vice versa, according to the settings of each independent channel.Moving this slider generates 5 different voltages with 5 different ranges and directions. The transition can also be operated from a CV source at the CV IN, in which case the slider position acts as an attenuator for the incoming voltage.The maximum range of each channel can be set to either 5 or 10 volts, by 5 jumpers in the back of the module. Only positive voltages are generated at the output.Using the CV IN you can use two ADDAC306 modules to expand your control options to 9 voltage outputs under one common slider control.Use the VC Transitions to multiply the polyphony of a single CV sequencer by passing its outputs through the ADDAC207.VC Transitions makes for an awesome state transition controller. Plug its outputs to various CV controller parameters of your audio effects modules. Set the slider to position A, and set the minimum values for each channel. Then move the slider to position B and set the SPAN settings for each channel. Use the TRANSITION CONTROLLER slider to morph from state A to state B and backwards. Flip the DIRECTION switches to change the direction of the transition for each channel. Use the CV IN to automate the transition using LFOs, ADSRs or sequencers.Plug the output of your ADSR envelope to the CV IN and set the channels differently to get 5 different ADSRs from one common source.This module's development was based on an initial idea by Konstantine Fioretos.DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 710 Balanced Outputs

available

ADDAC710 is a dual channel Isolated DI box and is all about keeping the sound coming from your Modular free from any undesired noisy interferences, making sure that what you’re getting from your outputs is what your Modular is actually producing. It provides galvanic electrical isolation between the Modular system and external sources preventing impedance mismatch and ground loop induced hum.ADDAC’s 710 circuit is designed around a unity 1:1 type Audio Transformer operating in the 20 Hz to 20 KHz range, this impedance matching transformer provides two fully balanced outputs (via XLR connectors).ADDAC710 is an alternative to our ADDAC800X High-End Outputs module, we redesigned the original circuit using a smaller transformer that also reduced it’s depth allowing it to fit shallow Eurorack cases.The LIFT/FLOAT/GND 3-way switch lets you choose between lift, ground or floating ground.In the LIFT position (left) the module circuit will be “lifted” to ground through a 100R resistor and a 10nF capacitor.In the FLOAT position (middle) Ground will not be shared leaving ins and outs grounds completely apart from each other fully isolating both signals.in the GND position (right) Ground will be shared between inputs and outputs, here no isolation is used.Any of these three positions may be the best form of avoiding ground loops or any other undesired interference occurring between your modular and the sound system you’re plugging it into.Try out which one of these options will work best in any given situation.DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 714 Vintage Clip

available

ADDAC714 is a dual channel soft clipping module.Diode based passive clipping acts as a “brick wall” limiter with a fixed knee given by the inherent diode physics. A passive RC low pass circuit adds a 3,3KHz -3db low pass filter which sculpts the overall tone while also adding further character to the effect.At the top an On/Off [BYPASS] switch routes the signal into the Effect (Up: Active) or to the bottom output gain stage (Down: Bypassed).The amount of clipping is set by the [GAIN] control, it mostly works as a threshold control for how much clipping will be applied. As more clipping is applied the signal’s amplitude will also decrease, to compensate for this we set up a gain compensation stage to keep the output amplitude balanced across the Gain range.Symmetry chooses between bipolar clipping or positive clipping, this relates to the harmonics generated, bipolar for odd and even harmonics (up position) and unipolar for odd harmonics only (down position).At the second stage, an op-amp based x2 output gain with a clipping led, which monitors the clipping at the output, and an [Output] control to set the output volume.Having the top and middle gain stages provides flexibility allowing the user to completely distort the signal on the top stage and tame it’s output level with the second stage.At the bottom, Input jacks for both channels (Left input is normalled into Right input) and output jacksDIY-Kit-Type:SMD-Kit-1.

ADDAC System - 805 VC Signal Router V2

available

Inspired by our ADDAC701 VCO waveform mixing section, our new VC Signal Router also updates our legacy X-Fade/Panner to a stereo configuration that also allows 4 quadrant mixing.Featuring two dedicated X-faders and a stereo VCA that can also be used as a third X-Fader. All controls have their own CV inputs and dedicated Attenuverters for precision control.4 quadrant mixing is achieved by using the stereo Master as a X-fader between left and right channels, this way you can plug 4 audio sources and sweep/crossfade between each and any of them using the 3 x-faders. Plug any 4 sources (4 waveforms of a VCO, 4 LFOs, 4 envelopes...) and sweep through morph through or have them all mixed together.For other configuration types Left and Right X-fader channels can be routed through the Master stereo VCA or sent directly to the outputs. A stereo Direct input can also be routed through the Master VCA or sent straight to the outputs.The Mono Sum output always mix Left and Right outputs together allowing the possibility to use the module as a peculiar 6 channel mono mixer.It can be used for both Audio or CV Signals.Features:• 6 mono inputs• 2 dedicated X-faders with Control knob + CV Input and Attenuverter Each X-fader can be routed through the Master mix or straight into the outputs.• Master channel can be used as a stereo VCA or an X-fader• Stereo direct inputs can be routed through the Master mix or straight into the outputs.• Fully analog audio path with high quality/low noise VCAs.DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 900 Power Delay NEW - PDN

only 2 left

This small board was designed to bring some extra flexibility and customization regarding powering up a modular system.Whenever a modular system is turned on there's a current spike upon startup that will momentarily influence the PSU output and can take up to a couple seconds for the PSU to stabilize to it's stated specifications. PSUs can also have some delay between their power lines where one polarity is provided prior to the second one. They also commonly have a ramp like startup. All this is common and normally not a problem. While most modules are fine with this situation, there are others that can suffer from this and in a worst case scenario won't startup correctly. Some modules can also be sensitive to the timing of the ±12v, some may require both to arrive at the same time others won't start if -12v arrives prior to the +12v, etc.This small board allows to time the deployment of power to a specific module, it can delay each power line independently by 3 seconds, meaning that after powering up your modular it will wait for 3 seconds until it will provide power to the specific module connected to it. This delay time can also be customized by the user replacing a couple capacitors.Using this small board with more sensitive modules allow them to power up at a time past the initial spike and where the PSU is already stable and it will guarantee that the ±12V is delivered at exactly the same time.Besides this very technical use there are other creative and useful uses, for example plug it to those specific modules that "drive" your patch, like a sequencer or a clock and have them power up later so that other modules have time to start up and stabilize before starting up the clock. Go even deeper in this idea and have diferent 900PDs with diferent capacitors that will allow you to "program" a sequential module power up, useful for generative patches that run on a power timer in exhibitions and galleries.One more useful hack is to use it in those cases where your frame won't power up due to the initial current "spike", making it going over its limits and trip the protection mechanism failing to startup. The usual "hack" is to unplug one or two modules allowing it to power up and then connect the extra modules in. ***Warning*** power up issues like these simply means your PSU is close to its maximum and the pcb shouldn't be used as a permanent fix and we advise upgrading the PSU. However it will make it easier in that situation where you add one last minute module for that gig in a few hours and that extra module trips the psu protection, then as a temporary hack the pcb will make it easier for the frame to power up at the gig.There are 2 sets of jumpers to independently set the power line to be delayed, -12V, +12V or both.This pcb will be plugged onto your busboard and, in turn, allow a ribbon power cable to be connected to it.There are 2 models ADDAC901PDO for Old style Busboards and ADDAC901PDN for New style BusboardsDISCLAIMER: Both the ADDAC901PDO and the ADDAC901PDN are not to be used with modules that require external +5V supply.DIY-Kit-Type:SMD-Kit-1.
