The UAD Fairchild 670 VST Mono plug-in still exists. How to update old sessions that use the UAD Fairchild 670 AU Mono plug-inīefore we get started, I want to point out two things:ġ) The regular version of the UAD Fairchild 670 AU plug-in does not use any additional DSP resources on your UAD card compared to the mono version.Ģ) Only the UAD Fairchild 670 AU Mono plug-in has been removed from the UAD 5.4.0 software. Next, and most importantly, Do Not Panic!! (Shout-out to Hawkwind fans.) The solution is very simple, so please read on, dear friends. When you get this message, do not save the session, or else the settings for your UAD Fairchild 670 AU Mono plug-in will be lost. So the question arises, What do I do if I have some old sessions/projects that use the Fairchild 670 AU Mono plug-in, and I’ve just installed UAD v5.4.0? First of all, if you try to load these sessions you will get a 'plug-in not found' error message. Some UAD users experienced problems using the UAD Fairchild 670 AU Mono plug-in, and so we decided to remove it from the new UAD v5.4.0 software to improve the performance and reliability of your UAD products. But, as the sun rises, so does it set, and thus we have the passing of an old friend: the UAD Fairchild 670 AU Mono plug-in. UAD version 5.4.0 hit the streets of a new world with many new features and plug-ins. Time flies, so we fast forward to July 29, 2009. Remember that mix, when you put that mono AU Fairchild 670 on the vocal track? Remember the smile you got when you heard the rich and silken sound? Ahh, good times, good times. Hiccup!') The world rejoiced! Now the sound of the Fairchild 670’s 14 transformers and 20 vacuum tubes would sing in many a DAW (huzzah!).

Actually, it was January 14, 2004, when Universal Audio released UAD version 3.4.0 and the birth cries of the new UAD Fairchild 670 plug-in could be heard.
