Old Organ that has MIDI (5 pin out) how to connect to SQ7?

Old Organ that has MIDI (5 pin out) how to connect to SQ7? Thinking I just need a MIDI five pin to XLR 3, and use an AUX on the SQ7? All I want is audio, not MIDI control. As I understand it MIDI uses pins 3.4.5 to XLR, 1 and 3, and I can just pad them if the connection is unbalanced versus balanced. The organ is really old, actually surprised it even has MIDI. It has no other outs. And just placing a mic near it works… not great at all.

I’m confused. To my knowledge midi does not pass audio, only control signals. Is it possible that you only have a midi control surface and not an organ? Seems like this device is destined to plug into something other than a sound board.

I see you say that it produces sound locally (you can put a mic near it). If it doesn’t have any type of audio output then it looks like it was not designed to be interfaced with a sound board. Seems like you would need to continue using the mic or hard wire some sort of jack into whatever speaker is producing the sound you are hearing.

What looks like a MIDI connector to you is a so called DIN connector that was originally used mostly for home electronics and HiFi equipment before it was used as MIDI connector. It still can be found on old turntables, hifi amplifiers and alike.

pin 1: record left
pin 2: ground
pin 3: playback left
pin 4: record right
pin 5: Playback right

just be careful, as the numbering is not subsequent!
What you would need is a adapter from 5 pole to RCA + RCA-Jack adapters + 2x DI Box to connect it to your SQ

RS: Cool. I learned something new. Thank you
