I have a couple of PS2 midi cables that I used with my Soundblaster Platinum back in the day. They are not Y cables but I wonder if I could use one instead of a Y cable? I would only need Midi out anyway, I do believe for syncing a looper. Thanks for the info.
I believe @neophytte have made a schematic for the pins.

Hope this helps.
