Question about midi output 3.3v/5v

[Effraktor]

just wondering if the 3.3v/5v pin on the midi output on the megadrum actually provides voltage? im not familiar with the midi standard and how typical it is to have it output power.

Need to know since i just ordered a "widi master" https://www.cme-pro.com/widi-master-wha ... o-for-you/

that seems like it should work well with my old zendrum i built using a megadrum brain in order to make it wireless. Just need to check if the megadrum cricuit outputs midi power already or if i will need to wire power to it myself.

MIDI communication works as current loop for signalling without any power pins/source.
