simple. what you want to do is set up your OT midi so that it sends pg chang to a spare channel. for example 16. then set up the other machines to listen for pg change on that same channel.
should just change on its own while the arranger is running. also keep in mind that octa track has double to banks. when changing to bank I pattern 7 you will send the A4 and MD back to the first bank A pattern 7.
