A fellow TT-303 user! Nice to meet you. Check out Coz's local thread on the 303:
viewtopic.php?f=11&t=164910Not that I am glad you are having this issue, but at least it comfirms I am not alone.
But it brings up another question: how is it that it has not happened to more people? Setting up my hardware synths was literally the first thing I did with the Ren out of the box and I discovered the issue in about 5 seconds flat. Surely other people are using the Ren with outboard synths and drum machines...
Anyway, I did reinstall to fix it.* My trick was to install 1.0, go to the "sync" menu (which was on the tool bar in the first version) and check the boxes that I wanted to sync (they dropped the boxes by 1.3.1) and then install 1.3.1. Sounds crazy, but it felt as if the 1.3.1 update didn't acknowledge that I actually wanted to send clock and that doing it in the 1.0 updated a preference file someplace. But it could also all be in my mind. Anyway, please let us know how it turned out, as there seems to be a bug in the mix here.
*Note that my DAW was due for a clean OS reinstall, so I actually wiped the DAW and then reinstalled all of my apps and drivers fresh, starting w/ the Ren. This was a royal pain in the ass and perhaps overkill... but it did get me full clock out on two ports at least
(Akai: please add clock on all four ports! Signed - everyone who has more than two pieces of hardware in their rig).
