Let's hope you never have to do this, but if (like me) you do, here's how to go about it. Thanks to Markus at Awave for the vital clues about the Mac file system, and for actually answering tech support emails! As a [former] cross platform developer, it's hard to believe that EMagic aren't familiar with these issues, but if they are, they've kept mum about it--I've been trying to get answers from EMagic on this since october, with no success. Markus at Awave took about 24 hours to clarify the whole situation. Hopefully someone else will benefit from this someday. Keywords LAW LAM Sound Designer filetype conversion LSO SD2 SDII resource fork This post explains how to open up a Logic project created in Logic on a Mac, and saved to a Mac format CD, in LAW. It requires two additional PC programs, MacOpener and Awave (or equivalents.) MacOpener allows a PC to open and read a Mac-format CD. Awave will batch-convert files from SD2 or aiff to WAV. When a mac disk is opened on a PC using MacOpener, the information in the resource fork (other than filetype and creator) of the files is lost. In the case of SDII files, this means the sample rate and the number of channels. Normally the sample rate will be the same as the song, so this is easy enough to ascertain. But the information about the number of channels is lost. Logic assumes it is 1. If the file is stereo, it will sound like it is playing back at half speed. Apparently this is why LAM doesn't support SDII files--the header data in it is lost when it is moved off a Mac. (Of course, your Logic song knows how many channels the file is SUPPOSED to have, so you'd think it could make an educated guess! But it doesn't.) Fetchit has a means of moving this data out of the resource fork, and into the file, where AWAVE can use it in the conversion, but MacOpener doesn't support this. So here is the process I have figured out to open such songs: 1. Add a new SDII filetype in MacOpener. Type is Sd2f, Creator is "any". This is done in MacOpener Driver prefs. 2. Set SDII extension to be blank. (It will need to be changed to .SD2 for Awave to work, but that comes later--if you let macopener rename the files now, Logic won't recognise them.) 3. Set up LSO filetype in MacOpener. Type is EM3F, Creater is EMAG. Now you should see extensions on your files. If this doesn't work, you may need to click on maclic.exe in the macOpener program files folder, and/or eject and remount the CD. Sometimes you have to restart. 4. Copy all audio songfiles from the CD onto the internal drive. 5. Open up your logic song. Mono files will play back correctly in Logic, even though SD2 is not supported. That's because there is nothing but audio data left in the file. Move all the mono files to your hard drive. Close Logic. 6. Go to MacOpener preferences, and set the SDII filetype extension to .SD2. Now your files should have an extension added. If not, see #3 above. 7. Open Awave. Use the "add directory" feature to add all the files with the .SD2 extension in the song folder on the CD. Remove any that you moved in step 5 from the list. On the next page of the wizard, click on "more options" and set the number of channels for SDII files to 2. You should now be able to go back to the Awave file page, and hear the stereo files play back correctly. 8. Convert the files to .wav files in Awave. Set # of channels to 2, and specify the sample rate if the default is not correct (default is 44100.) 9. Open up Logic. It cannot automatically recognise the .wav files when it opens, so you will have to select each one of them manually. Alternatively, It might work to remove the .wav extensions from all the files in the finder, so logic sees them. 10. Play your song, and hope it sounds right. If you mistook a mono file for stereo, it will play back an octave too high. If this happens, go to "more options" in the AWAVE and change the number of SDII channels back to 1. Run the .wav conversion on the original CD file again. Now if you find it in logic, it will say "mono/stereo conflict", so you will have to reopen your song from the CD, and go through manually finding all the stereo files again. It will also ask for the converted mono file. This time it won't complain. Hope this helps somebody someday.
