Many moons ago, I created numerous music files using the PC version of Logic Audio Platinum (Version 3.5, 1998). Is there some way to open these files with a Mac version of Logic, or Mac third party software?
The latest PC version is 5.5.1. All more or less recent Mac versions (read: 6, 7, 8 and 9) will open songs created (or re-saved) in that version. Unfortunately, no others but the internal plugins will load automatically.
Songs created in earlier versions need to be opened and re-saved in either Logic 5, 6 or 7 to be compatible with 8 or 9.
Unfortunately, you won't be able to purchase any older versions straight from Apple anymore, and you'll probably also have a tough time finding them 2nd hand. So it's probably the best idea to find some person(s) who would help you out and re-save a few songs for you. If you want, feel free to drop me a line, I still have version 5 installed on a PC, so I could perhaps "convert" a few of your songs.
And if I purchase a Mac and a Mac version of Logic 7, how do I access files located on a disk formatted for PC, or a PC hard drive?
From what I know, this is what Steinberg is doing. In order to open Cubase VST (and older versions) songs in Cubase 5 they need to be opened and re-saved in SX, so that's what they're giving away for free to Cubase 5 users (of course you still need the dongle to run it). Quite a good move, if you ask me.
