I apologize, I got the name wrong. EDIT: ah, I see you figured it out, but I’ll leave this for posterity. It’s the circled button (hold FUNC first before pressing obvs) and then you tick the MOut. For each track. Fortunately it’s a quick operation because you can change tracks quickly and it stays on this menu option. Also easy enough to copy patterns with it already set up.
Yeah, you’d think, right? I can’t figure out why it was implemented this way. I guess you can have some patterns/tracks with MIDI turned on and some not, but I can’t think of a strong reason for that. Great machines otherwise.
