Midiphy - nexusMIDI (Assembled)

Product information "Midiphy - nexusMIDI (Assembled)"

nexusMIDI is a 6HP Eurorack phybus expander that adds four classic DIN MIDI ports to connected midiphy modules such as zetaSID. With two MIDI inputs and two MIDI outputs in standard 5-pin DIN format, it makes it easy to connect external keyboards, controllers, sequencers, DAWs and MIDI hardware to a phybus-based modular setup.

Designed as the central MIDI gateway for zetaSID and other phybus instruments, nexusMIDI enables polyphonic MIDI keyboard control, MIDI clock synchronization, modulation via pitch bend and mod wheel, velocity-sensitive dynamics, SysEx patch transfer and ASID SID-file playback. In combination with multiple zetaSID modules, it turns a phybus instrument cluster into a classic MIDI-controlled polyphonic synthesizer with up to six stereo voices.

The module uses reliable standard MIDI circuitry for stable communication, even with longer MIDI cables. MIDI data can be routed through the phybus network using virtual patching, reducing cable clutter while keeping connected modules flexible and recallable. Status LEDs provide clear visual feedback for MIDI activity and available ports, making nexusMIDI practical in both studio and live setups.

With its high-quality milled aluminium front panel, compact 30mm depth and standard Eurorack power connection, nexusMIDI is a focused expansion module for musicians who want to integrate zetaSID and phybus systems with traditional MIDI workflows.

Product Safety Information

Please read this safety guide before installation or use.

Important Notice & Intended Use
• This kit is intended for adult users experienced in electronics and modular synthesis.
• Assembly, including soldering, is required.
• Proper testing and installation are essential to ensure safe and functional operation.
• The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
• Use outside this scope may result in malfunction, damage, or safety risks.

General Warnings

Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.

Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.

Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.

Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.

Compatibility:
• This module is designed specifically for Eurorack-compatible systems. Connecting it to non-compatible systems may result in damage or malfunction.

Assembly Requirements
• Soldering skills are required to complete the module.
• Ensure a clean, well-lit and ventilated workspace free of flammable materials during assembly.
• Use appropriate tools and safety equipment, such as eye protection.

Testing
• Test the module thoroughly for shorts or incorrect assembly before powering it in your Eurorack system. When the unit has malfunctions due to incorrect assembly, the entire Eurorack system might be damaged. It's a good idea to test it in a separate case with only that single module.
• Use a multimeter or other appropriate tools to confirm proper functionality.

Installation and Use
• Mount securely in a Eurorack case using the provided screws.
• Use only the included or manufacturer-recommended power cable.
• Connect only when the power is off.
• Follow the module's user guide for instructions on operation. Do not exceed the input/output limits specified.

Responsibility
Users are solely responsible for proper assembly and testing. Contact manufacturer support for assistance if needed.

Environmental Safety
• Dispose of the module, its components, and packaging in accordance with local electronic waste regulations.

Liability Disclaimer
• The manufacturer or distributor is not responsible for any injury, damage, or malfunction resulting from improper installation, use, or modification of this product.
