H9 modification for MIDI power

Some product, for example, those from MIDI Solutions, rely on power being supplied by the connected MIDI Output socket.

H9's before Serial 16329 did not supply this power, but a simple modification can be made to remedy this.

Instructions are attached (ignore first page) - soldering is required, but it should only take 5 minutes for a skilled person.

This only applies to H9 - 'Factors do not have this issue.

Would it be practical to send power out the unused pins of the MIDI ~INPUT~?

Cuz I could get behind self-powered MIDI controllers.
