@d-healey thanx for your fast response as always
found the issue , akai daw have 2 ways to set / re scan your plug-ins, 1 is in preference and the other is in the plug-in manager, there was the confusion, so I went to the preference / plug-in folder/ and select my Mac hd/laudio/vst and also AU FOLDER, it seems akai route the search by default to its own plug in folder (VST3/au) in its own directory, you need to add other locations manually, PROBLEM SOLVED,thanx
