Hi - I have been searching high and low for some time now trying to find detailed specifications for the 7-pin DIN connector and especially information about pins 6 & 7 since pins 1-5 are as I understand it identical to the 5-pin DIN connector - please feel free to correct me if I am wrong. I am in the process of constructing a MIDI device with the intention of being powered and in turn passing power via the 7-pin DIN (female) connectors and need to ensure I have the right specs. Since there are a number of MIDI devices on the market utilizing 7-pin MIDI DIN connectors, where pins 6 & 7 carry the current (V) I assume a specification exists and would very much appreciate a hint of where I can get a copy.
Thank you very much in advance!

The 7-pin connector was chosen because it is compatible with 5-pin ones, so the first five pins indeed must be the same.
There is no official specification for power over MIDI cables.
The pinout that most (all?) devices use is shown here: http://wiki.fractalaudio.com/axefx2/index.php?title=FAMC_Liquid_Foot%2B#MIDI_IN%2E2FOUT_Pinout_Specs_for_5pin_and_7pin
Power could be anything: 9 V, 12 V, or maybe more, and DC or AC. So you probably need a voltage regulator and a bridge rectifier.
