I too have been having problems with the UAD card and have tried the work around using the IO plug in but it does not always work. Here is my question for you. When you assign the IO plug in to the audio or audio instrument track on which you wish to use a UAD plug in when you designate the input and output on the deactivated plugin what settings are you using. For example, say I want to use a pultec eq on audio instrument 1 (and I have put an exs24 instrument on audio track one with a kick drum in mono)> So I put a Logic IO helper in the top plug in slot, however, out of the available choices I do not know which input number to select. I usually select output 9 because 9 corresponds with my main analog out in my asio configuration. If you could point out what I am doing wrong it would be greatly appreciated. I am using the following gear: G4 450, OS 9.2.2, 512 megs ram, Logic Audio Platinum 6.0, Sound Diver, 3.04, UAD-1 card, Motu PCI-324 card, Waves Gold Bundle Native, Absynth, Virtual Guitarist, Unitor 8 II, AMT8. I am using the Motu PCI-324 console v. 2.4 which when installed placed asio driver version 2.1 in my Logic ASIO drivers folder, and placed PCI-324 Sound Manager Driver v. 1.2. in my extensions folder, and placed the PCI driver v. 1.5 in my extension folder as well. thanks daviscremar@...
