WIDI Master gets its power from the MIDI OUT or THRU port of the MIDI device you connect it to. Always make sure that the large main adapter is connected to the MIDI OUT or THRU port. This process is explained in the quick start guide.
The standard MIDI OUT or THRU port supplies 3.3v or 5v via the 5-pin DIN MIDI connector. It is a standard as proposed by the International MIDI Association.
If your WIDI Master does not start up, first check that no LED indicator is visible. Once you’re sure you’ve plugged it in correctly, you can do a number of things.
Option 1: Check out the open source compatibility list to see if your device is listed and validated by the community.
Option 2:Â Create your own DIY power solution

Option 3:Â Ground your WIDI Master
When WIDI Master is not getting power from the instrument, it is usually a problem of missing ground on the instrument side. The midi specification mentions ground should be connected to midi out din pin 2 but it is not mandatory.
What you can try is to add a wire between the WIDI Master DIN shield (in or out) and the instrument ground. If your instrument has a metal case it should be connected to its ground, so you can use a screw to connect the wire.
Option 4:Â Get yourself WIDI Jack + 5-PIN DIN cable option
If your WIDI Master is not powered by the MIDI device you attach it to, please go to the WIDI Jack product page and order WIDI Jack + 5-PIN DIN bundle. Add an external power supply via USB-C (this is NOT a MIDI USB port).
