Just to chip in, I have O&C (I'm also running the original firmware), and as I far as I know, what you want to do isn't possible - asking O&C to re-trigger itself.
Actually, it's one of the oddest things about O&C. It's, as some say, the Swiss army knife of modular, but some of the most obvious things you'd love it to do .... it doesn't! You can freeze sequences, alter them on the fly either yourself or via algorithms, and more. Yet to have a simple possibility to clock or trigger itself, and in some of the modes a possibility to stop or start, it doesn't do. However, it's a brilliant module, and as you already said 'diving down the rabbit hole of O&C is much fun, and often very productive.
