Hello Andrew, I just read your post about the Tuner plug-in. I can confirm that the Tuner plug-in is in fact (still) working in Logic Pro 7.2 I tested it with OS X 10.4.5 <I've upgraded to the new 7.2 and noticed the Tuner plug-in no longer works. ,> <Anyone have an idea for a fix?> Some ideas to try; Try opening Logic without an Autoload if you have one setup. Repair permissions. Insert the Tuner plug-on as mono on an Aux and set it's output to outs 1-2 and it's input to input 1. Hope that helps :-) Best regards. John Hart
