Has anyone got the Garritan Personal Orchestra 4 working in Logic Express? I cannot get GPO 4 to appear in my Logic Express no matter how I try. I have followed instructions for setting it up in Logic Pro (from You Tube) and all goes well until I click the grey area under the I/O box. This is where I should find the 'All instruments - Garritan - GPO 4' links to open up the GPO 4 Aria player but there is no sign of these links at all, I have tried clicking various boxes but all to no avail. The Logic instruments play properly so its nothing to do with my set up and the GPO 4 plays in my Sibelius software so it must be installed correctly. I am using a Mac OS X, I would be grateful for a possible solution. Thanks.
