From reading through, obviously we're all aware there are UAD issues in Reason. Not taking sides, but there is a clear (proven) explanation of what causes the issue and why it's not an issue in other DAWs in this post here viewtopic.php?p=351809#p351809.
Lets take that as what it is. No one from Propellerhead commented in this thread so no one knows what the future is, and whether or not there will ever be a fix. It's unfortunate that some purchased the upgrade to 9.5 specifically to use UAD plugins and ran into this issue. The 9.5 beta only ran here for a month, and the only way Propellerhead would have caught this beforehand is if they themselves had owned UAD plugins and hardware (it's very likely they didn't). Truth is at this point, there's nothing that can be done but to wait and see if there's ever a fix. Arguing about surely wont do anything.
Please keep this thread civil. I'll have to lock it otherwise.
