I'm afraid your problem might be with win8 drivers - you probably do need to conatact roland.  I don't think I can be of any help with that - I'm still on win7.

Thanks Beagle, I'm going to continue with the last of the Windows updates but, the UA-4FX was being recognized in MC-6 ASIO setting at first. It isn't any longer. It won't allow me to un-install or re-install the drivers and gives me an error message. I have made an email inquiry at Roland. And, I hope I won't have this issue with the VS-100's Win 8 64 drivers. I have downloaded them and read the instructions. There's also a firmware 1.5 update for the VS-100. I hope both Cakewalk and/or Roland will be proactive with supporting their products integration. I've already hit the wall with trying to use the UA-FX. It's in Advanced driver mode as indicated in the readme file. I'll keep you and the forum posted. Thanks again,

I was able to find this document. It seems to be loading the drivers. Tech support sent me a boilerplate reply and sent me down the worm-hole. I hope this helps all who make the jump... http://www.rolandus.com/s...dge_base/view/23719573 UA-4FX: SYMPTOM: Driver Will Not Install (Windows) Knowledge Base Id: 23719573 Tags: driver, install, problems, windows The following steps will guide you through an alternative driver installation process in the event that you are receiving an error message or the driver will not install properly on your computer.
