Is it safe to say that a midi controller that can be powered through a 5 pin midi cable will not see power when the pitchfactor is added between the device and the power source?
It is safe to say …
Don't know which pins you are using -there is no standard for this sort of power connection. The MIDI 1.0 Specification says that pins 1 and 3 are unused and should not be connected.
Some products, including our Eclipse and early Orvilles, used a 7 pin connector with the extra pins available for power.
