This is a great game.
It nice that someone went through the trouble of putting together an audio mixer, especially as a game, it's something that I could play for hours. You have some really nice sounds in there. Thanks, and keep up the good work. Oh, and you may want to mention to people that they can also use Audacity to save their tracks. To export it as mp3s though, they'll need to download the "dll" files, but it's all free.
