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.

The Noise Swash is a chaotic random noise-maker and CV generator, generating its own sounds or working as an audio processor. As a stand-alone device it generates unpredictable continuously morphing oscillations on the Audio Output jack, and random CV fluctuations out the dual-direction "Mood CV" jack. A second CV input jack controls the Swash and Noisegate sections with positive and negative CV voltage. An audio input jack allows for distorting an audio signal beyond recognition, or using audio to trigger and modulate the chaos. The Swash knob is a 10-turn Bourns pot for adjusting minor variations. Each Swash has its own peculiarly unique sound.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module.

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)
