4ms - Meta Module

available

The MetaModule puts real knobs and jacks on virtual software modules. Step back from the computer and make music with hardware, while keeping the flexibility and expandability of software.THIS PRODUCT IS ASSEMBLED AND NO DIY!The MetaModule comes with over 160 built-in modules from 4ms Company, Befaco, HetrickCV, NonlinearCircuits, and Scanner Darkly, plus clones of popular classics such as the Mutable Instruments Eurorack modules, fun physical modeling algorithms, and lots of handy utilities.All of the included modules are also available on the computer using the free program VCV Rack. Whether you make patches on VCV Rack and transfer them to the MetaModule, or if you just create patches directly on the MetaModule, there are plenty of creative modules to inspire new ways to make music.MetaModule PluginsIf the 160+ built-in module aren’t enough, you can load more modules as plugins. Already there are over 200 modules in third-party plugins from Bogaudio, Valley, ChowDSP, NANO Modular, and the list is growing. We have an SDK available to make it easy for VCV Rack plugin developers to convert their plugin to a MetaModule plugin. Our licensing terms are non-restrictive: developers are welcome to distribute their plugin in any way they wish, commercially or not.Mapping Knobs and JacksThe MetaModule has 12 knobs that can be mapped to virtual knobs. Each knob can be mapped to up eight virtual knobs, and each mapping can have a different range and offset. You also can save a group of mappings as a Knob Set and switch between Knob Sets with the encoder. You also can map the 8 inputs and 8 outputs to virtual module jacks. Also, the MetaModule is a USB MIDI host, so you also can map MIDI CC, note, gate, and other parameters to knobs and jacks.ExpandersThere are lots of ways to customize your MetaModule. A Wifi expander allows you to wirelessly transfer patches from your computer. Add eight more knobs with the Knob expander, or buttons with the Button expander. A CV/Audio expander adds more high-resolution inputs and outputs, and the Gate In/Out expander adds not only gate jacks but also TRS MIDI and I2C.Under the HoodThere are six CV/Audio inputs, two gate inputs, and six CV/Audio outputs. The CV/Audio jacks are all 24-bit, 48kHz DC-coupled, -10V to +10V. A USB-C jack accepts MIDI devices and thumb drives. Patches and plugins can be loaded via a USB drive or microSD Card, and internal flash memory lets you save patches you always want to come back to.The processor is more advanced than anything 4ms has used in the past, and is among the most powerful processors found in Eurorack. Startup time and latency are blazingly fast.Features:Patches• Patches are loaded from microSD Card, USB drive, or via the Wifi expander• Patches can be optionally saved onto internal flash memory• Create patches using VCV Rack or directly on MetaModule• Patches can be given a name and descriptionMappings• Map each physical knob to up to 8 virtual knobs• Set range and offset for each mapping, including inverted control• Knob mappings are grouped into Knob Sets, and changing Knob Sets can be done quickly without menu-diving• Map physical jacks to virtual jacks, seamlessly making splits/mults• Add or edit modules, cables, and mappings in real-time while the patch is playing• Create alias names for mappings like "Kick Drum Level"Interface• Simple, intuitive graphical interface lets you zoom in on details, or zoom out to get a big picture• Patch View displays the patch as faceplates and cables, with knobs, buttons, and lights animating in real-time• Knob Set View simplifies the display, showing only the mapped knobs for the current Knob Set• Module View shows just one module and lists the names of each jack, knob, and control legibly• Mapping View lets you adjust details of a knob mapping• Adjust styles and visual preferences to your liking• Save, rename, duplicate, and delete patches• Firmware updater and plugin loader read from microSD Card or USB driveHardware• 12 Knobs• 8 CV/Audio outputs, 24-bit 48kHz, -10V to +10V, DC-coupled• 6 CV/Audio inputs, 24-bit 48kHz, -10V to +10V, DC-coupled• 2 Gate inputs• USB-C jack: MIDI Host or MSC (External drive) Host• microSD Card slot• Internal Flash RAM for additional patch storage• Dual-core 800MHz Cortex-A7 plus Cortex-M4 co-processor• 512MB DDR3 533MHz RAM• Bare-metal operation for fast startup and low latencyDIY-Kit-Type:Assembled unit.

ADDAC System - 203 CV Mapping

available

This is a new revision of one of our first modules, back from 2010. Now more compact in 6 HP and with an Offset CV input.The incoming signal amplitude is controlled by a [GAIN] attenuverter circuit allowing to attenuate the signal as well as invert its phase. A back jumper can set the maximum gain amount to either x1 (unity gain) or x10. DIY modifications can be made by changing its resistors. After the Gain an offset can be added to the signal, displacing the signal up or down (-5V to +5V) this can be adjusted using the [OFFSET] knob and CV input.When using no input using the [OFFSET] knob and CV input will generate an output between -5V and +5V.DIY-Kit-Type:SMD-Kit-1.

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.

Stereo Strip takes the idea of a channel strip and makes it modular.

Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.This module is designed in collaboration with Ben Wilson aka Divkid.Features:• 3 band EQ• Panning (manual and voltage controlled)• VCA level control (manual or voltage controlled)• 3 way performance muting (on-off-momentary)• Soft clipping limiter (distortion!)• Line level input and/or output adjustmentDIY-Kit-Type:SMD-Kit-1.
