The Hub

The open source MIDI thru hub is the first PIRATE MIDI Gizmo to be released into the wild. When you purchase this kit, you'll receive a completely assembled circuit board with 10 3.5mm TRS jacks, 9v DC plug, and USB type-c (power only) ready to plug and play. You'll also receive fasteners and acrylic plates to assemble it into the pictured configuration. The package also contains an Allen key for assembly. The top acrylic plate arrives with laser etched markings for the connectors as well as the dipswitch configuration legend.


The MIDI Thru Hub has 8 dipswitches which you can configure to set each of the 8 configurable outputs to TRS MIDI

  • Type A
  • Type B
  • Tip Active
  • Ring Active

There is also a dedicated MIDI out/thru for a total of 9 MIDI outs on the board. MIDI is input via the dedicated 3.5mm TRS jack.

A standard 2.1mm DC barrel jack is provided for center negative power, or you can power via the USB type-C connector. The USB is not used for MIDI or any kind of data - it is intended for power only.

Open Source

This means you can access all the files, schematics, and bill of materials on our public PIRATE MIDI Gizmos Github repository. You're free to do whatever you like with the design and files. If you want to modify the device and make the new changes available for other people, go for it! If you want to manufacture them yourselves and leave us out of it - that's fine too.

If you have any interesting changes or design files (enclosures, PCB changes, mods etc) make sure to submit a pull request on the Github repository so we can make your contribution available to everyone.


We have the parts ready to go to build these, so we just need some orders so we can get them sent out to you. They won't be shipped immediately, but it won't be a long wait. If you want to ask us how it's going, the best place is in our PIRATE MIDI Facebook Group. Or you can email us at support@piratemidi.com
