how do I make AIFF or Wav. files that will play on a basic Cd player ? The simplest way ...
the most simple way is to burn the CD from GB's Share menu
next is to create a playlist in iTunes, export the project(s) _uncompressed_ to iTunes, place them in that playlist, and use iTunes to burn that playlist to the CD.
either method will create an audio CD rather than a data CD (which will not play in most consumer level CD players)
