I had no problems at all installing and getting set up with the Universal Audio UAD-1 Project Pak. I had no compatibility issues at all, but it did take a few minutes to install the DSP board. However, once this is installed it doesn't need to be touched again and will be ready whenever you need it. The interface of the plug-ins in general is easy to follow, as they are all laid out smartly, with everything easy to find. The manual for the Universal Audio UAD-1 Project Pak is thorough and complete, and is definitely good to have around while you are installing and using this powerful plug-in bundle.
Out of all the plug-ins in the Universal Audio UAD-1 Project Pak, I would say that I use the CS-1 Channel Strip and the Pultec EQP-1A the most, but just about all of the plug-ins in the Project Pak and good sounding and useful. The thing that astounds me the most is the wide variety of plug-ins that are available within this suite, ranging from just about every type of signal processing you can think of.
I've been using the Universal Audio UAD-1 Project Pak plug-in suite for about two years and have found it to be one of the best deals on the market in terms of plug-in bundles. The DSP board makes for not only a top notch sound quality, but the plug-ins also run extremely fast. The price is probably the best part as it is extremely cheap, which makes it perfect for home studio owners. All in all, the Universal Audio UAD-1 Project Pak is an awesome plug-in pack that is great for all types of studio owners and engineers.
