My (perhaps simplistic) understanding of this is that once you have entered a song, it has to be "generated" to play (the process where the program creates all the instrument parts). Once you've done this, if you press "play", the program does not create all the parts again, it just plays what it has previously created - thus saving you the few seconds the computer takes to create all the parts. However, if you press "generate and play", the program again creates all the parts (and it will be slightly different from what was produced before).

So if you've got a song already created (lets call this version 1), and then you enter some changes (like turning off the ending - thus creating version 2). Now if you press "play" the program is going to still play version 1. You've got to press "generate and play" to produce (and hear) version 2. Now once you've produced (or generated) version 2 of your song, you can use "play" to hear it again...

Hope that helps some. Good luck!
