Check out this thread. Some sweet Rytm ambient pieces there.
I’ve had the Rytm twice and despite failing to make it work for my music I still would like to have another go with it. Having said that, many if not most of the Rytm tracks that I’ve found great have been mostly or entirely sample-based. So like you said, someone hijacking Rytm and using it like an OT. For me personally OT, MD and A4 have proven to be better drum machines. Maybe look for a used Rytm mk1 to try it out? 1300 for a black mk2 doesn’t sound like a once in a lifetime deal.
